CHAPTER 1
Installation
1.1 Introduction
Selenium Python bindings provides a simple API to write functional/acceptance tests using Selenium WebDriver.
Through Selenium Python API you can access all functionalities of Selenium WebDriver in an intuitive way.
Selenium Python bindings provide a convenient API to access Selenium WebDrivers like Firefox, Ie, Chrome, Remote
etc. The current supported Python versions are 2.7, 3.5 and above.
This documentation explains Selenium 2 WebDriver API. Selenium 1 / Selenium RC API is not covered here.
1.2 Downloading Python bindings for Selenium
You can download Python bindings for Selenium from the PyPI page for selenium package. However, a better ap-
proach would be to use pip to install the selenium package. Python 3.6 has pip available in the standard library. Using
pip, you can install selenium like this:
pip install selenium
You may consider using virtualenv to create isolated Python environments. Python 3.6 has pyvenv which is almost the
same as virtualenv.
1.3 Drivers
Selenium requires a driver to interface with the chosen browser. Firefox, for example, requires geckodriver, which
needs to be installed before the below examples can be run. Make sure it’s in your PATH, e. g., place it in /usr/bin or
/usr/local/bin.
Failure to observe this step will give you an error selenium.common.exceptions.WebDriverException: Message: ‘geck-
odriver’ executable needs to be in PATH.
3

Other supported browsers will have their own drivers available. Links to some of the more popular browser drivers
follow.
Chrome: https://sites.google.com/a/chromium.org/chromedriver/downloads
Edge: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
Firefox: https://github.com/mozilla/geckodriver/releases
Safari: https://webkit.org/blog/6900/webdriver-support-in-safari-10/
1.4 Detailed instructions for Windows users
Note: You should have an internet connection to perform this installation.
1. Install Python 3.6 using the MSI available in python.org download page.
2. Start a command prompt using the cmd.exe program and run the pip command as given below to install
selenium.
C:Python35Scriptspip.exe install selenium
Now you can run your test scripts using Python. For example, if you have created a Selenium based script and saved
it inside C:my_selenium_script.py, you can run it like this:
C:Python35python.exe C:my_selenium_script.py
1.5 Downloading Selenium server
Note: The Selenium server is only required if you want to use the remote WebDriver. See the Using Selenium
with remote WebDriver section for more details. If you are a beginner learning Selenium, you can skip this section
and proceed with next chapter.
Selenium server is a Java program. Java Runtime Environment (JRE) 1.6 or newer version is recommended to run
Selenium server.
You can download Selenium server 2.x from the download page of selenium website. The ﬁle name should be some-
thing like this: selenium-server-standalone-2.x.x.jar. You can always download the latest 2.x version
of Selenium server.
If Java Runtime Environment (JRE) is not installed in your system, you can download the JRE from the Oracle website.
If you are using a GNU/Linux system and have root access in your system, you can also use your operating system
instructions to install JRE.
If java command is available in the PATH (environment variable), you can start the Selenium server using this com-
mand:
java -jar selenium-server-standalone-2.x.x.jar
Replace 2.x.x with the actual version of Selenium server you downloaded from the site.
4 Chapter 1. Installation

If JRE is installed as a non-root user and/or if it is not available in the PATH (environment variable), you can type
the relative or absolute path to the java command. Similarly, you can provide a relative or absolute path to Selenium
server jar ﬁle. Then, the command will look something like this:
/path/to/java -jar /path/to/selenium-server-standalone-2.x.x.jar

CHAPTER 2
Getting Started
2.1 Simple Usage
If you have installed Selenium Python bindings, you can start using it from Python like this.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()
The above script can be saved into a ﬁle (eg:- python_org_search.py), then it can be run like this:
python python_org_search.py
The python which you are running should have the selenium module installed.
2.2 Example Explained
The selenium.webdriver module provides all the WebDriver implementations. Currently supported WebDriver imple-
mentations are Firefox, Chrome, IE and Remote. The Keys class provide keys in the keyboard like RETURN, F1, ALT
etc.
7

Next, the instance of Firefox WebDriver is created.
The driver.get method will navigate to a page given by the URL. WebDriver will wait until the page has fully loaded
(that is, the “onload” event has fired) before returning control to your test or script. It’s worth noting that if your page
uses a lot of AJAX on load then WebDriver may not know when it has completely loaded.:
The next line is an assertion to confirm that title has “Python” word in it:
assert "Python" in driver.title
WebDriver offers a number of ways to find elements using one of the find_element_by_* methods. For example, the
input text element can be located by its name attribute using find_element_by_name method. A detailed explanation
of finding elements is available in the Locating Elements chapter:
Next, we are sending keys, this is similar to entering keys using your keyboard. Special keys can be sent using Keys
class imported from selenium.webdriver.common.keys. To be safe, we’ll first clear any pre-populated text in the input
field (e.g. “Search”) so it doesn’t affect our search results:
elem.clear()
After submission of the page, you should get the result if there is any. To ensure that some results are found, make an
assertion:
Finally, the browser window is closed. You can also call quit method instead of close. The quit will exit entire browser
whereas close‘ will close one tab, but if just one tab was open, by default most browser will exit entirely.:
driver.close()
2.3 Using Selenium to write tests
Selenium is mostly used for writing test cases. The selenium package itself doesn’t provide a testing tool/framework.
You can write test cases using Python’s unittest module. The other options for a tool/framework are py.test and nose.
In this chapter, we use unittest as the framework of choice. Here is the modified example which uses unittest module.
This is a test for python.org search functionality:
import unittest
class PythonOrgSearch(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Firefox()
(continues on next page)
8 Chapter 2. Getting Started

(continued from previous page)
def test_search_in_python_org(self):
driver = self.driver
self.assertIn("Python", driver.title)
def tearDown(self):
self.driver.close()
if __name__ == "__main__":
unittest.main()
You can run the above test case from a shell like this:
python test_python_org_search.py
.
----------------------------------------------------------------------
Ran 1 test in 15.566s
OK
The above result shows that the test has been successfully completed.
2.4 Walk through of the example
Initially, all the basic modules required are imported. The unittest module is a built-in Python based on Java’s JUnit.
This module provides the framework for organizing the test cases. The selenium.webdriver module provides all the
WebDriver implementations. Currently supported WebDriver implementations are Firefox, Chrome, Ie and Remote.
The Keys class provide keys in the keyboard like RETURN, F1, ALT etc.
import unittest
The test case class is inherited from unittest.TestCase. Inheriting from TestCase class is the way to tell unittest module
that this is a test case:
The setUp is part of initialization, this method will get called before every test function which you are going to write
in this test case class. Here you are creating the instance of Firefox WebDriver.
def setUp(self):
This is the test case method. The test case method should always start with characters test. The ﬁrst line inside this
method create a local reference to the driver object created in setUp method.
driver = self.driver
2.4. Walk through of the example 9

The driver.get method will navigate to a page given by the URL. WebDriver will wait until the page has fully loaded
(that is, the “onload” event has fired) before returning control to your test or script. It’s worth noting that if your page
uses a lot of AJAX on load then WebDriver may not know when it has completely loaded.:
The next line is an assertion to confirm that title has “Python” word in it:
self.assertIn("Python", driver.title)
WebDriver offers a number of ways to find elements using one of the find_element_by_* methods. For example, the
input text element can be located by its name attribute using find_element_by_name method. Detailed explanation of
finding elements is available in the Locating Elements chapter:
Next, we are sending keys, this is similar to entering keys using your keyboard. Special keys can be send using Keys
class imported from selenium.webdriver.common.keys:
After submission of the page, you should get the result as per search if there is any. To ensure that some results are
found, make an assertion:
The tearDown method will get called after every test method. This is a place to do all cleanup actions. In the current
method, the browser window is closed. You can also call quit method instead of close. The quit will exit the entire
browser, whereas close will close a tab, but if it is the only tab opened, by default most browser will exit entirely.:
def tearDown(self):
self.driver.close()
Final lines are some boiler plate code to run the test suite:
if __name__ == "__main__":
unittest.main()
2.5 Using Selenium with remote WebDriver
To use the remote WebDriver, you should have Selenium server running. To run the server, use this command:
java -jar selenium-server-standalone-2.x.x.jar
While running the Selenium server, you could see a message looking like this:
15:43:07.541 INFO - RemoteWebDriver instances should connect to: http://127.0.0.
˓→1:4444/wd/hub
The above line says that you can use this URL for connecting to remote WebDriver. Here are some examples:
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

driver = webdriver.Remote(
command_executor='http://127.0.0.1:4444/wd/hub',
desired_capabilities=DesiredCapabilities.CHROME)
desired_capabilities=DesiredCapabilities.OPERA)
desired_capabilities=DesiredCapabilities.HTMLUNITWITHJS)
The desired capabilities is a dictionary, so instead of using the default dictionaries, you can specify the values explic-
itly:
desired_capabilities={'browserName': 'htmlunit',
'version': '2',
'javascriptEnabled': True})
2.5. Using Selenium with remote WebDriver 11

CHAPTER 3
Navigating
The first thing you’ll want to do with WebDriver is navigate to a link. The normal way to do this is by calling get
method:
driver.get("http://www.google.com")
WebDriver will wait until the page has fully loaded (that is, the onload event has fired) before returning control to
your test or script. It’s worth noting that if your page uses a lot of AJAX on load then WebDriver may not know when
it has completely loaded. If you need to ensure such pages are fully loaded then you can use waits.
3.1 Interacting with the page
Just being able to go to places isn’t terribly useful. What we’d really like to do is to interact with the pages, or, more
specifically, the HTML elements within a page. First of all, we need to find one. WebDriver offers a number of ways
to find elements. For example, given an element defined as:
<input type="text" name="passwd" id="passwd-id" />
you could find it using any of:
element = driver.find_element_by_id("passwd-id")
element = driver.find_element_by_name("passwd")
element = driver.find_element_by_xpath("//input[@id='passwd-id']")
You can also look for a link by its text, but be careful! The text must be an exact match! You should also be careful
when using XPATH in WebDriver. If there’s more than one element that matches the query, then only the first will be
returned. If nothing can be found, a NoSuchElementException will be raised.
WebDriver has an “Object-based” API; we represent all types of elements using the same interface. This means
that although you may see a lot of possible methods you could invoke when you hit your IDE’s auto-complete key
combination, not all of them will make sense or be valid. Don’t worry! WebDriver will attempt to do the Right Thing,
and if you call a method that makes no sense (“setSelected()” on a “meta” tag, for example) an exception will be
raised.
13

So, you’ve got an element. What can you do with it? First of all, you may want to enter some text into a text field:
element.send_keys("some text")
You can simulate pressing the arrow keys by using the “Keys” class:
element.send_keys(" and some", Keys.ARROW_DOWN)
It is possible to call send_keys on any element, which makes it possible to test keyboard shortcuts such as those used
on GMail. A side-effect of this is that typing something into a text field won’t automatically clear it. Instead, what
you type will be appended to what’s already there. You can easily clear the contents of a text field or textarea with the
clear method:
element.clear()
3.2 Filling in forms
We’ve already seen how to enter text into a textarea or text field, but what about the other elements? You can “toggle”
the state of the drop down, and you can use “setSelected” to set something like an OPTION tag selected. Dealing with
SELECT tags isn’t too bad:
element = driver.find_element_by_xpath("//select[@name='name']")
all_options = element.find_elements_by_tag_name("option")
for option in all_options:
print("Value is: %s" % option.get_attribute("value"))
option.click()
This will find the first “SELECT” element on the page, and cycle through each of its OPTIONs in turn, printing out
their values, and selecting each in turn.
As you can see, this isn’t the most efficient way of dealing with SELECT elements. WebDriver’s support classes
include one called a “Select”, which provides useful methods for interacting with these:
from selenium.webdriver.support.ui import Select
select = Select(driver.find_element_by_name('name'))
select.select_by_index(index)
select.select_by_visible_text("text")
select.select_by_value(value)
WebDriver also provides features for deselecting all the selected options:
select = Select(driver.find_element_by_id('id'))
select.deselect_all()
This will deselect all OPTIONs from that particular SELECT on the page.
Suppose in a test, we need the list of all default selected options, Select class provides a property method that returns
a list:
select = Select(driver.find_element_by_xpath("//select[@name='name']"))
all_selected_options = select.all_selected_options
To get all available options:
options = select.options
14 Chapter 3. Navigating

Once you’ve finished filling out the form, you probably want to submit it. One way to do this would be to find the
“submit” button and click it:
# Assume the button has the ID "submit" :)
driver.find_element_by_id("submit").click()
Alternatively, WebDriver has the convenience method “submit” on every element. If you call this on an element within
a form, WebDriver will walk up the DOM until it finds the enclosing form and then calls submit on that. If the element
isn’t in a form, then the NoSuchElementException will be raised:
element.submit()
3.3 Drag and drop
You can use drag and drop, either moving an element by a certain amount, or on to another element:
element = driver.find_element_by_name("source")
target = driver.find_element_by_name("target")
from selenium.webdriver import ActionChains
action_chains = ActionChains(driver)
action_chains.drag_and_drop(element, target).perform()
3.4 Moving between windows and frames
It’s rare for a modern web application not to have any frames or to be constrained to a single window. WebDriver
supports moving between named windows using the “switch_to_window” method:
driver.switch_to_window("windowName")
All calls to driver will now be interpreted as being directed to the particular window. But how do you know the
window’s name? Take a look at the javascript or link that opened it:
<a href="somewhere.html" target="windowName">Click here to open a new window</a>
Alternatively, you can pass a “window handle” to the “switch_to_window()” method. Knowing this, it’s possible to
iterate over every open window like so:
for handle in driver.window_handles:
driver.switch_to_window(handle)
You can also swing from frame to frame (or into iframes):
driver.switch_to_frame("frameName")
It’s possible to access subframes by separating the path with a dot, and you can specify the frame by its index too.
That is:
driver.switch_to_frame("frameName.0.child")
would go to the frame named “child” of the first subframe of the frame called “frameName”. All frames are evaluated
as if from *top*.
3.3. Drag and drop 15

Once we are done with working on frames, we will have to come back to the parent frame which can be done using:
driver.switch_to_default_content()
3.5 Popup dialogs
Selenium WebDriver has built-in support for handling popup dialog boxes. After you’ve triggered action that would
open a popup, you can access the alert with the following:
alert = driver.switch_to_alert()
This will return the currently open alert object. With this object, you can now accept, dismiss, read its contents or even
type into a prompt. This interface works equally well on alerts, conﬁrms, prompts. Refer to the API documentation
for more information.
3.6 Navigation: history and location
Earlier, we covered navigating to a page using the “get” command ( driver.get("http://www.example.
com")) As you’ve seen, WebDriver has a number of smaller, task-focused interfaces, and navigation is a useful task.
To navigate to a page, you can use get method:
driver.get("http://www.example.com")
To move backward and forward in your browser’s history:
driver.forward()
driver.back()
Please be aware that this functionality depends entirely on the underlying driver. It’s just possible that something
unexpected may happen when you call these methods if you’re used to the behavior of one browser over another.
3.7 Cookies
Before we leave these next steps, you may be interested in understanding how to use cookies. First of all, you need to
be on the domain that the cookie will be valid for:
# Go to the correct domain
driver.get("http://www.example.com")
# Now set the cookie. This one's valid for the entire domain
cookie = {‘name’ : ‘foo’, ‘value’ : ‘bar’}
driver.add_cookie(cookie)
# And now output all the available cookies for the current URL
driver.get_cookies()

CHAPTER 4
Locating Elements
There are various strategies to locate elements in a page. You can use the most appropriate one for your case. Selenium
provides the following methods to locate elements in a page:
• find_element_by_id
• find_element_by_name
• find_element_by_xpath
• find_element_by_link_text
• find_element_by_partial_link_text
• find_element_by_tag_name
• find_element_by_class_name
• find_element_by_css_selector
To find multiple elements (these methods will return a list):
• find_elements_by_name
• find_elements_by_xpath
• find_elements_by_link_text
• find_elements_by_partial_link_text
• find_elements_by_tag_name
• find_elements_by_class_name
• find_elements_by_css_selector
Apart from the public methods given above, there are two private methods which might be useful with locators in page
objects. These are the two private methods: find_element and find_elements.
Example usage:
17

from selenium.webdriver.common.by import By
driver.find_element(By.XPATH, '//button[text()="Some text"]')
driver.find_elements(By.XPATH, '//button')
These are the attributes available for By class:
ID = "id"
XPATH = "xpath"
LINK_TEXT = "link text"
PARTIAL_LINK_TEXT = "partial link text"
NAME = "name"
TAG_NAME = "tag name"
CLASS_NAME = "class name"
CSS_SELECTOR = "css selector"
4.1 Locating by Id
Use this when you know id attribute of an element. With this strategy, the ﬁrst element with the id attribute value
matching the location will be returned. If no element has a matching id attribute, a NoSuchElementException
will be raised.
For instance, consider this page source:
<html>
<body>
<form id="loginForm">
<input name="username" type="text" />
<input name="password" type="password" />
<input name="continue" type="submit" value="Login" />
</form>
</body>
<html>
The form element can be located like this:
login_form = driver.find_element_by_id('loginForm')
4.2 Locating by Name
Use this when you know name attribute of an element. With this strategy, the ﬁrst element with the name attribute value
matching the location will be returned. If no element has a matching name attribute, a NoSuchElementException
will be raised.
<html>
<body>
18 Chapter 4. Locating Elements

<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
The username & password elements can be located like this:
username = driver.find_element_by_name('username')
password = driver.find_element_by_name('password')
This will give the “Login” button as it occurs before the “Clear” button:
continue = driver.find_element_by_name('continue')
4.3 Locating by XPath
XPath is the language used for locating nodes in an XML document. As HTML can be an implementation of XML
(XHTML), Selenium users can leverage this powerful language to target elements in their web applications. XPath
extends beyond (as well as supporting) the simple methods of locating by id or name attributes, and opens up all sorts
of new possibilities such as locating the third checkbox on the page.
One of the main reasons for using XPath is when you don’t have a suitable id or name attribute for the element you
wish to locate. You can use XPath to either locate the element in absolute terms (not advised), or relative to an element
that does have an id or name attribute. XPath locators can also be used to specify elements via attributes other than id
and name.
Absolute XPaths contain the location of all elements from the root (html) and as a result are likely to fail with only
the slightest adjustment to the application. By ﬁnding a nearby element with an id or name attribute (ideally a parent
element) you can locate your target element based on the relationship. This is much less likely to change and can make
your tests more robust.
<html>
<body>
<input name="continue" type="button" value="Clear" />
</form>
</body>
<html>
The form elements can be located like this:
login_form = driver.find_element_by_xpath("/html/body/form[1]")
login_form = driver.find_element_by_xpath("//form[1]")
login_form = driver.find_element_by_xpath("//form[@id='loginForm']")
1. Absolute path (would break if the HTML was changed only slightly)
2. First form element in the HTML
3. The form element with attribute named id and the value loginForm
4.3. Locating by XPath 19

The username element can be located like this:
username = driver.find_element_by_xpath("//form[input/@name='username']")
username = driver.find_element_by_xpath("//form[@id='loginForm']/input[1]")
username = driver.find_element_by_xpath("//input[@name='username']")
1. First form element with an input child element with attribute named name and the value username
2. First input child element of the form element with attribute named id and the value loginForm
3. First input element with attribute named ‘name’ and the value username
The “Clear” button element can be located like this:
clear_button = driver.find_element_by_xpath("//input[@name='continue'][@type='button']
˓→")
clear_button = driver.find_element_by_xpath("//form[@id='loginForm']/input[4]")
1. Input with attribute named name and the value continue and attribute named type and the value button
2. Fourth input child element of the form element with attribute named id and value loginForm
These examples cover some basics, but in order to learn more, the following references are recommended:
• W3Schools XPath Tutorial
• W3C XPath Recommendation
• XPath Tutorial - with interactive examples.
There are also a couple of very useful Add-ons that can assist in discovering the XPath of an element:
• XPath Checker - suggests XPath and can be used to test XPath results.
• Firebug - XPath suggestions are just one of the many powerful features of this very useful add-on.
• XPath Helper - for Google Chrome
4.4 Locating Hyperlinks by Link Text
Use this when you know link text used within an anchor tag. With this strategy, the ﬁrst element with the
link text value matching the location will be returned. If no element has a matching link text attribute, a
NoSuchElementException will be raised.
<html>
<body>
<p>Are you sure you want to do this?</p>
<a href="continue.html">Continue</a>
<a href="cancel.html">Cancel</a>
</body>
<html>
The continue.html link can be located like this:
continue_link = driver.find_element_by_link_text('Continue')
continue_link = driver.find_element_by_partial_link_text('Conti')

4.5 Locating Elements by Tag Name
Use this when you want to locate an element by tag name. With this strategy, the first element with the given tag name
will be returned. If no element has a matching tag name, a NoSuchElementException will be raised.
<html>
<body>
<h1>Welcome</h1>
<p>Site content goes here.</p>
</body>
<html>
The heading (h1) element can be located like this:
heading1 = driver.find_element_by_tag_name('h1')
4.6 Locating Elements by Class Name
Use this when you want to locate an element by class attribute name. With this strategy, the first element
with the matching class attribute name will be returned. If no element has a matching class attribute name, a
NoSuchElementException will be raised.
<html>
<body>
<p class="content">Site content goes here.</p>
</body>
<html>
The “p” element can be located like this:
content = driver.find_element_by_class_name('content')
4.7 Locating Elements by CSS Selectors
Use this when you want to locate an element by CSS selector syntax. With this strategy, the first element with the
matching CSS selector will be returned. If no element has a matching CSS selector, a NoSuchElementException
will be raised.
<html>
<body>
<p class="content">Site content goes here.</p>
</body>
<html>
The “p” element can be located like this:
4.5. Locating Elements by Tag Name 21

content = driver.find_element_by_css_selector('p.content')
Sauce Labs has good documentation on CSS selectors.

CHAPTER 5
Waits
These days most of the web apps are using AJAX techniques. When a page is loaded by the browser, the elements
within that page may load at different time intervals. This makes locating elements difﬁcult: if an element is not yet
present in the DOM, a locate function will raise an ElementNotVisibleException exception. Using waits, we can solve
this issue. Waiting provides some slack between actions performed - mostly locating an element or any other operation
with the element.
Selenium Webdriver provides two types of waits - implicit & explicit. An explicit wait makes WebDriver wait for a
certain condition to occur before proceeding further with execution. An implicit wait makes WebDriver poll the DOM
for a certain amount of time when trying to locate an element.
5.1 Explicit Waits
An explicit wait is a code you deﬁne to wait for a certain condition to occur before proceeding further in the code.
The extreme case of this is time.sleep(), which sets the condition to an exact time period to wait. There are some
convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in
combination with ExpectedCondition is one way this can be accomplished.
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver.get("http://somedomain/url_that_delays_loading")
try:
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "myDynamicElement"))
)
finally:
driver.quit()
23

This waits up to 10 seconds before throwing a TimeoutException unless it finds the element to return within 10 sec-
onds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A
successful return is for ExpectedCondition type is Boolean return true or not null return value for all other Expected-
Condition types.
Expected Conditions
There are some common conditions that are frequently of use when automating web browsers. Listed below are
the names of each. Selenium Python binding provides some convenience methods so you don’t have to code an
expected_condition class yourself or create your own utility package for them.
• title_is
• title_contains
• presence_of_element_located
• visibility_of_element_located
• visibility_of
• presence_of_all_elements_located
• text_to_be_present_in_element
• text_to_be_present_in_element_value
• frame_to_be_available_and_switch_to_it
• invisibility_of_element_located
• element_to_be_clickable
• staleness_of
• element_to_be_selected
• element_located_to_be_selected
• element_selection_state_to_be
• element_located_selection_state_to_be
• alert_is_present
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.ID, 'someid')))
The expected_conditions module contains a set of predefined conditions to use with WebDriverWait.
Custom Wait Conditions
You can also create custom wait conditions when none of the previous convenience methods fit your requirements.
A custom wait condition can be created using a class with __call__ method which returns False when the condition
doesn’t match.
class element_has_css_class(object):
"""An expectation for checking that an element has a particular css class.
locator - used to find the element
returns the WebElement once it has the particular css class
"""
def __init__(self, locator, css_class):
24 Chapter 5. Waits

self.locator = locator
self.css_class = css_class
def __call__(self, driver):
element = driver.find_element(*self.locator) # Finding the referenced element
if self.css_class in element.get_attribute("class"):
return element
else:
return False
# Wait until an element with id='myNewInput' has class 'myCSSClass'
wait = WebDriverWait(driver, 10)
element = wait.until(element_has_css_class((By.ID, 'myNewInput'), "myCSSClass"))
5.2 Implicit Waits
An implicit wait tells WebDriver to poll the DOM for a certain amount of time when trying to ﬁnd any element (or
elements) not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the
WebDriver object.
driver.implicitly_wait(10) # seconds
driver.get("http://somedomain/url_that_delays_loading")
myDynamicElement = driver.find_element_by_id("myDynamicElement")

CHAPTER 6
Page Objects
This chapter is a tutorial introduction to page objects design pattern. A page object represents an area in the web
application user interface that your test is interacting.
Beneﬁts of using page object pattern:
• Creating reusable code that can be shared across multiple test cases
• Reducing the amount of duplicated code
• If the user interface changes, the ﬁx needs changes in only one place
6.1 Test case
Here is a test case which searches for a word in python.org website and ensure some results are found.
import unittest
import page
"""A sample test class to show how page object works"""
def setUp(self):
self.driver.get("http://www.python.org")
"""
Tests python.org search feature. Searches for the word "pycon" then verified
˓→that some results show up.
Note that it does not look for any particular text in search results page.
˓→This test verifies that
the results were not empty.
27

"""
#Load the main page. In this case the home page of Python.org.
main_page = page.MainPage(self.driver)
#Checks if the word "Python" is in title
assert main_page.is_title_matches(), "python.org title doesn't match."
#Sets the text of search textbox to "pycon"
main_page.search_text_element = "pycon"
main_page.click_go_button()
search_results_page = page.SearchResultsPage(self.driver)
#Verifies that the results page is not empty
assert search_results_page.is_results_found(), "No results found."
def tearDown(self):
self.driver.close()
if __name__ == "__main__":
unittest.main()
6.2 Page object classes
The page object pattern intends creating an object for each web page. By following this technique a layer of separation
between the test code and technical implementation is created.
The page.py will look like this:
from element import BasePageElement
from locators import MainPageLocators
class SearchTextElement(BasePageElement):
"""This class gets the search text from the specified locator"""
#The locator for search box where search string is entered
locator = 'q'
class BasePage(object):
"""Base class to initialize the base page that will be called from all pages"""
def __init__(self, driver):
self.driver = driver
class MainPage(BasePage):
"""Home page action methods come here. I.e. Python.org"""
#Declares a variable that will contain the retrieved text
search_text_element = SearchTextElement()
def is_title_matches(self):
"""Verifies that the hardcoded text "Python" appears in page title"""
return "Python" in self.driver.title
def click_go_button(self):
28 Chapter 6. Page Objects

"""Triggers the search"""
element = self.driver.find_element(*MainPageLocators.GO_BUTTON)
element.click()
class SearchResultsPage(BasePage):
"""Search results page action methods come here"""
def is_results_found(self):
# Probably should search for this text in the specific page
# element, but as for now it works fine
return "No results found." not in self.driver.page_source
6.3 Page elements
The element.py will look like this:
from selenium.webdriver.support.ui import WebDriverWait
class BasePageElement(object):
"""Base page class that is initialized on every page object class."""
def __set__(self, obj, value):
"""Sets the text to the value supplied"""
driver = obj.driver
WebDriverWait(driver, 100).until(
lambda driver: driver.find_element_by_name(self.locator))
driver.find_element_by_name(self.locator).clear()
driver.find_element_by_name(self.locator).send_keys(value)
def __get__(self, obj, owner):
"""Gets the text of the specified object"""
driver = obj.driver
WebDriverWait(driver, 100).until(
lambda driver: driver.find_element_by_name(self.locator))
element = driver.find_element_by_name(self.locator)
return element.get_attribute("value")
6.4 Locators
One of the practices is to separate the locator strings from the place where they are being used. In this example,
locators of the same page belong to same class.
The locators.py will look like this:
class MainPageLocators(object):
"""A class for main page locators. All main page locators should come here"""
GO_BUTTON = (By.ID, 'submit')
6.3. Page elements 29

class SearchResultsPageLocators(object):
"""A class for search results locators. All search results locators should come
˓→here"""
pass

32 Chapter 7. WebDriver API

exception selenium.common.exceptions.ElementNotVisibleException(msg=None,
screen=None,
stack-
trace=None)
Thrown when an element is present on the DOM, but it is not visible, and so is not able to be interacted with.
Most commonly encountered when trying to click or read text of an element that is hidden from view.
exception selenium.common.exceptions.ErrorInResponseException(response, msg)
Thrown when an error has occurred on the server side.
This may happen when communicating with the firefox extension or the remote driver server.

trace=None)
Thrown when activating an IME engine has failed.
exception selenium.common.exceptions.ImeNotAvailableException(msg=None,
screen=None,
stack-
trace=None)
Thrown when IME support is not available. This exception is thrown for every IME-related method call if IME
support is not available on the machine.
exception selenium.common.exceptions.InsecureCertificateException(msg=None,
screen=None,
stack-
trace=None)
Navigation caused the user agent to hit a certificate warning, which is usually the result of an expired or invalid
TLS certificate.

7.1. Exceptions 33

exception selenium.common.exceptions.InvalidCoordinatesException(msg=None,
screen=None,
stack-
trace=None)
The coordinates provided to an interactions operation are invalid.
exception selenium.common.exceptions.InvalidElementStateException(msg=None,
screen=None,
stack-
trace=None)
Thrown when a command could not be completed because the element is in an invalid state.
This can be caused by attempting to clear an element that isn’t both editable and resettable.
exception selenium.common.exceptions.InvalidSelectorException(msg=None,
screen=None,
stack-
trace=None)
Bases: selenium.common.exceptions.NoSuchElementException
Thrown when the selector which is used to ﬁnd an element does not return a WebElement. Currently this only
happens when the selector is an xpath expression and it is either syntactically invalid (i.e. it is not a xpath
expression) or the expression does not select WebElements (e.g. “count(//input)”).
exception selenium.common.exceptions.InvalidSessionIdException(msg=None,
screen=None,
stack-
trace=None)
Occurs if the given session id is not in the list of active sessions, meaning the session either does not exist or
that it’s not active.

screen=None, stack-
trace=None)
An error occurred while executing JavaScript supplied by the user.
exception selenium.common.exceptions.MoveTargetOutOfBoundsException(msg=None,
screen=None,
stack-
trace=None)
Thrown when the target provided to the ActionsChains move() method is invalid, i.e. out of document.
exception selenium.common.exceptions.NoAlertPresentException(msg=None,
screen=None,
stacktrace=None)

Thrown when switching to no presented alert.
This can be caused by calling an operation on the Alert() class when an alert is not yet on the screen.
exception selenium.common.exceptions.NoSuchAttributeException(msg=None,
screen=None,
stack-
trace=None)
Thrown when the attribute of element could not be found.
You may want to check if the attribute exists in the particular browser you are testing against. Some browsers
may have different property names for the same property. (IE8’s .innerText vs. Firefox .textContent)
exception selenium.common.exceptions.NoSuchCookieException(msg=None,
screen=None, stack-
trace=None)
No cookie matching the given path name was found amongst the associated cookies of the current browsing
context’s active document.
exception selenium.common.exceptions.NoSuchElementException(msg=None,
screen=None,
stacktrace=None)
Thrown when element could not be found.
If you encounter this exception, you may want to check the following:
• Check your selector used in your find_by...
• Element may not yet be on the screen at the time of the find operation, (webpage is still loading)
see selenium.webdriver.support.wait.WebDriverWait() for how to write a wait wrapper to wait for an
element to appear.
exception selenium.common.exceptions.NoSuchFrameException(msg=None,
screen=None, stack-
trace=None)

• You are no longer on the same page, or the page may have refreshed since the element was located.
• The element may have been removed and re-added to the screen, since it was located. Such as an
element being relocated. This can happen typically with a javascript framework when values are
updated and the node is rebuilt.
• Element may have been inside an iframe or another context which was refreshed.
exception selenium.common.exceptions.TimeoutException(msg=None, screen=None,

7.2 Action Chains
The ActionChains implementation,
class selenium.webdriver.common.action_chains.ActionChains(driver)
Bases: object
ActionChains are a way to automate low level interactions such as mouse movements, mouse button actions,
key press, and context menu interactions. This is useful for doing more complex actions like hover over and
drag and drop.
Generate user actions. When you call methods for actions on the ActionChains object, the actions are stored
in a queue in the ActionChains object. When you call perform(), the events are ﬁred in the order they are
queued up.
ActionChains can be used in a chain pattern:
menu = driver.find_element_by_css_selector(".nav")
hidden_submenu = driver.find_element_by_css_selector(".nav #submenu1")
ActionChains(driver).move_to_element(menu).click(hidden_submenu).perform()
Or actions can be queued up one by one, then performed.:
menu = driver.find_element_by_css_selector(".nav")
hidden_submenu = driver.find_element_by_css_selector(".nav #submenu1")
actions = ActionChains(driver)
actions.move_to_element(menu)
actions.click(hidden_submenu)
actions.perform()
Either way, the actions are performed in the order they are called, one after another.

If the optional port number is provided, only IPs that listen on the given port are considered.
Args

• port - Optional port number.
Returns A single IP address, as a string. If any IPv4 address is found, one is returned. Otherwise, if
any IPv6 address is found, one is returned. If neither, then None is returned.

vice_log_path=’geckodriver.log’,

Bases: selenium.webdriver.remote.webdriver.WebDriver

executable_path=’geckodriver’, options=None, service_log_path=’geckodriver.log’, fire-
fox_options=None, service_args=None, desired_capabilities=None, log_path=None,
keep_alive=True)
Starts a new local session of Firefox.
Based on the combination and specificity of the various keyword arguments, a capabilities dictionary will
be constructed that is passed to the remote end.
The keyword arguments given to this constructor are helpers to more easily allow Firefox WebDriver
sessions to be customised with different options. They are mapped on to a capabilities dictionary that is
passed on to the remote end.
As some of the options, such as firefox_profile and options.profile are mutually exclusive, precedence is
given from how specific the setting is. capabilities is the least specific keyword argument, followed by
options, followed by firefox_binary and firefox_profile.
In practice this means that if firefox_profile and options.profile are both set, the selected profile instance will
always come from the most specific variable. In this case that would be firefox_profile. This will result in
options.profile to be ignored because it is considered a less specific setting than the top-level firefox_profile
keyword argument. Similarily, if you had specified a capabilities[“moz:firefoxOptions”][“profile”]
Base64 string, this would rank below options.profile.
7.12. Firefox WebDriver 49

Parameters
• firefox_profile – Instance of FirefoxProfile object or a string. If undefined,
a fresh profile will be created in a temporary location on the system.
• firefox_binary – Instance of FirefoxBinary or full path to the Firefox binary.

Appendix: Frequently Asked Questions
Another FAQ: https://github.com/SeleniumHQ/selenium/wiki/Frequently-Asked-Questions
8.1 How to use ChromeDriver ?
Download the latest chromedriver from download page. Unzip the ﬁle:
unzip chromedriver_linux32_x.x.x.x.zip
You should see a chromedriver executable. Now you can create an instance of Chrome WebDriver like this:
driver = webdriver.Chrome(executable_path="/path/to/chromedriver")
The rest of the example should work as given in other documentation.
8.2 Does Selenium 2 support XPath 2.0 ?
Ref: http://seleniumhq.org/docs/03_webdriver.html#how-xpath-works-in-webdriver
Selenium delegates XPath queries down to the browser’s own XPath engine, so Selenium support XPath supports
whatever the browser supports. In browsers which don’t have native XPath engines (IE 6,7,8), Selenium supports
XPath 1.0 only.
8.3 How to scroll down to the bottom of a page ?
Ref: http://blog.varunin.com/2011/08/scrolling-on-pages-using-selenium.html
You can use the execute_script method to execute javascript on the loaded page. So, you can call the JavaScript API
to scroll to the bottom or any other position of a page.
95

Here is an example to scroll to the bottom of a page:
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
The window object in DOM has a scrollTo method to scroll to any position of an opened window. The scrollHeight
is a common property for all elements. The document.body.scrollHeight will give the height of the entire body of the
page.
8.4 How to auto save files using custom Firefox profile ?
Ref: http://stackoverflow.com/questions/1176348/access-to-file-download-dialog-in-firefox
Ref: http://blog.codecentric.de/en/2010/07/file-downloads-with-selenium-mission-impossible/
The first step is to identify the type of file you want to auto save.
To identify the content type you want to download automatically, you can use curl:
curl -I URL | grep "Content-Type"
Another way to find content type is using the requests module, you can use it like this:
import requests
content_type = requests.head('http://www.python.org').headers['content-type']
print(content_type)
Once the content type is identified, you can use it to set the firefox profile preference: browser.helperApps.
neverAsk.saveToDisk
Here is an example:
import os
fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList",2)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir", os.getcwd())
fp.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/octet-stream
˓→")
browser = webdriver.Firefox(firefox_profile=fp)
browser.get("http://pypi.python.org/pypi/selenium")
browser.find_element_by_partial_link_text("selenium-2").click()
In the above example, application/octet-stream is used as the content type.
The browser.download.dir option specify the directory where you want to download the files.
8.5 How to upload files into file inputs ?
Select the <input type="file"> element and call the send_keys() method passing the file path, either the
path relative to the test script, or an absolute path. Keep in mind the differences in path names between Windows and
Unix systems.
96 Chapter 8. Appendix: Frequently Asked Questions

8.6 How to use firebug with Firefox ?
First download the Firebug XPI file, later you call the add_extension method available for the firefox profile:
fp = webdriver.FirefoxProfile()
fp.add_extension(extension='firebug-1.8.4.xpi')
fp.set_preference("extensions.firebug.currentVersion", "1.8.4") #Avoid startup screen
browser = webdriver.Firefox(firefox_profile=fp)
8.7 How to take screenshot of the current window ?
Use the save_screenshot method provided by the webdriver:
driver.get('http://www.python.org/')
driver.save_screenshot('screenshot.png')
driver.quit()
