Selenium with java
- 1. SELENIUM WITH JAVA GOUSALYA RAMACHANDRAN
- 2. WHY DO YOU NEED AUTOMATION? Automation helps to ease the repetitive tasks of Manual testers. Automation can cover many scenarios within a little time However automation does not replace manual testing. In fact, you have to test software manually before you run automated testing. Even though manual testing requires much effort, without it you cannot be sure that automation is possible.
- 3. WHAT IS SELENIUM? Selenium is an open source automation test suite of different tools focused to automate web application. Selenium consists of the following tools Selenium Integrated Development Environment (Selenium IDE) Selenium Remote Control (Selenium RC) Selenium WebDriver Selenium Grid
- 4. WHY WAS SELENIUM INTRODUCED? Repetitive testing JavaScriptExecutor As this is pure JS, requires to be placed within the application Selenium RC Allow the JavaScriptExecutor to be used by different applications Selenium IDE Firefox extension that can automate through a record-and- playback feature Selenium WebDriver Cross platform(not limited to JS) and control browser from OS level Selenium 2 Selenium 3 Improvements Selenium Grid Sending selenium commands to multiple machines
- 5. SELENIUM WEBDRIVER Unlike other selenium tools, WebDriver does not rely on JavaScript for Automation. It communicates directly to the browser Selenium WebDriver supports Java. C#, Ruby, Python, JS Like selenium , WebDriver can only support web based applications. Also, it cannot readily support new browsers
- 6. SELENIUM WEBDRIVER WITH JAVA - INSTALLATION 1. Install Java 2. Install Eclipse IDE 3. Download selenium client jar file from https://selenium.dev/downloads/ 4. Create a Java project 5. Import the downloaded jar files to your library
- 7. SELENIUM WEBDRIVER WITH JAVA - BASIC COMMANDS Getting a web page driver.get("www.javatpoint.com") driver.Navigate().to("https://javatpoint.com/selenium-tutorial"); <html> <head> </head> <body> <form method="post" action=""> <input type="text" id="Input1" name="Input tag 1" class="MyClass" value="This is the first input"/> </body> </html> Locating elements (Some of them are listed below) driver.findElement(By.id("id")) //Input1 driver.findElement(By.name("id")) //Input tag 1 driver.findElement(By.xpath("id")) // //input driver.findElement(By.cssSelector("id")) //input#Input1 driver.findElement(By.tagName("id")) // input driver.findElement(By.className("id")) // MyClass
- 8. SELENIUM WEBDRIVER WITH JAVA – BASIC COMMANDS Basic Input field commands driver.findElement(By.id("id")). sendKeys() clear() getText() click() Browser events (to use this we have to use driver.navigate().to("<url>")) driver.navigate().back(); driver.navigate().forward(); driver.navigate().refresh();
- 9. SELENIUM WEBDRIVER WITH JAVA – BASIC COMMANDS Closing the browser driver.close(); Close all the browser instances (windows) associated with the driver driver.quit(); Other commands Actions Switches getWindowHandles()/getWindowHandle() Handling alerts
- 10. SELENIUM WEBDRIVER WITH JAVA – WAIT COMMANDS Implicit wait Applied for the driver instance Wait before it throws a "No Such Element Exception". driver.manage().timeouts().implicitlyWait(<Time to wait>, TimeUnit.SECONDS); // Can be seconds, milliseconds, minutes etc. Explicit Wait Wait for certain conditions (Expected Conditions) to be ; True within the given time False when the given time exceeds Applied for specific element WebDriverWait wait = new WebDriverWait(<Webdriver variable name> ,<Time to wait in seconds>); WebElement elementName = wait.Until(ExpectedCondition.visibilityOfElementLocated(By.xpath("<xpath location>")));
- 11. SELENIUM WEBDRIVER WITH JAVA – WAIT COMMANDS Fluent Wait Wait for a condition, as well as the frequency with which we want to check the condition before throwing an exception Wait wait = new FluentWait(WebDriver reference) .withTimeout(timeout, SECONDS) .pollingEvery(timeout, SECONDS) .ignoring(Exception.class); Thread.sleep(<time in ms>) Helps to sleep / suspend the test execution for the given time. This is not recommended for code publishing. Can be used for debugging.
- 12. SELENIUM WEBDRIVER WITH JAVA – ASSERT AND VERIFY Both Assert and Verify commands are used to find whether a given input is present or not on the webpage. When an “assert” command fails, the test execution will be aborted. So when the Assertion fails, all the test steps after that line of code are skipped. When a “verify” command fails, the test will continue executing and logging the failure.
- 13. SELENIUM WEBDRIVER WITH JAVA – ASSERT AND VERIFY //ASSERTION Assert.assertEquals(ExpectedTitle, CurrentTitle); System.out.println("Step after assert") ; //Will not be executed if the above assert fails //To convert an assertion to verification, try{ Assert.assertEquals(ExpectedTitle, CurrentTitle); System.out.println("Verification passed"); }catch (Exception e){ System.out.println("Verification failed"); } System.out.println("Step after assert") ; //Will be executed if the above assert fails
- 14. SELENIUM WITH JAVA : SIMPLE CODE EXAMPLE Open Chrome browser Navigate to https://www.google.com Verify the Title Close the browser
- 15. SELENIUM WITH JAVA : SIMPLE CODE EXAMPLE import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class AS { public static void main(String[] args) { // The Path to your chrome driver System.setProperty("webdriver.chrome.driver", "G:chromedriver.exe"); // Creating the driver object WebDriver driver = new ChromeDriver(); String baseUrl = "http://www.google.com"; String expectedTitle = "Google"; String actualTitle = "";
- 16. SELENIUM WITH JAVA : SIMPLE CODE EXAMPLE // Navigate to the url using chrome driver.get(baseUrl); // get the actual value of the title actualTitle = driver.getTitle(); if (actualTitle.contentEquals(expectedTitle)) { System.out.println("Test Passed!"); } else { System.out.println("Test Failed"); } // close Chrome driver.close(); } }
