Web Testing
 The

possible web page features. A partial list
of them includes:
–

Text of different sizes, fonts, and colors (okay,
you can't see the colors in this book)
Graphics and photos
Hyperlinked text and graphics
Rotating advertisements
Text that has Drop-down selection boxes
Fields in which the users can enter data.

features that make the website
much more complex:

Customizable layout that allows users to change where
information is positioned onscreen
Customizable content that allows users to select what news
and information they want to see
Dynamic drop-down selection boxes
Dynamically changing text
Dynamic layout and optional information based on screen
resolution
Compatibility with different web browsers, browser versions,
and hardware and software platforms
Lots of hidden formatting, tagging, and embedded information
that enhances the web page's usability

Testing Web Page








The easiest place to start is by treating the web page
or the entire website as a black box.
When testing a website, you first should create a
state table
Treating each page as a different state with the
hyperlinks as the lines connecting them.
A completed state map will give a better view of the
overall task.

Web page text should be treated just like documentation
Check the audience level, the terminology, the content and subject matter,
the accuracy especially of information that can become outdated and
always, always check spelling.
Don't rely on spell checkers to be perfect, especially when they're used on
web page content. They might only check the regular text but not what's
contained in the graphics, scrolling marquees, forms, and so on.
If there is contact information such as email addresses, phone numbers, or
postal addresses, check them to make sure that they're correct.
Make sure that the copyright notices are correct and dated appropriately.
Test that each page has a correct title.
Overlooked type of text is called ALT text, for Alternate text
Not all browsers support display of the ALT text.

 Hyperlinks
–

–

Links can be tied to text or graphics. Each link
should be checked to make sure that it jumps to
the correct destination and opens in the correct
window.
Make sure that hyperlinks are obvious. Text links
are usually underlined, and the mouse pointer
should change (usually to a hand pointer) when
it's over any kind of hyperlink text or graphic.

Graphics

Do all graphics load and display properly?
If a graphic is missing or is incorrectly named, it won't load and the web
page will display an error where the graphic was to be placed
If text and graphics are intermixed on the page, make sure that the text
wraps properly around the graphics. Try resizing the browser's window to
see if strange wrapping occurs around the graphic.
How's the performance of loading the page?
Are there so many graphics on the page, resulting in a large amount of
data to be transferred and displayed, that the website's performance is too
slow?
What happens if you test on a slow dialup connection instead of your
company's fast local area network?

Forms

Forms are the text boxes, list boxes, and other fields for
entering or selecting information on a web page
Are the fields the correct size?
Do they accept the correct data and reject the wrong data?
Is there proper confirmation when you finally press Enter?
Are optional fields truly optional and the required ones truly
required?
What happens if you enter 99999999999999999999999?

Objects and Other Simple Miscellaneous
Functionality

Website may contain features such as a hit counter, scrolling marquee text,
changing advertisements, or internal site searches
When planning tests for a website, take care to identify all the features
present on each page.
Treat each unique feature as you would a feature in a regular program and
test it individually with the standard testing techniques.
Does it have its own states?
Does it handle data?
Could it have ranges or boundaries?
What test cases apply and how should they be equivalence classed?
A web page is just like any other software.

Hardware Platform. Is it a Mac, PC, PDA, MSNTV, or a WiFi wristwatch? Each
hardware device has its own operating system, screen layout, communications
software, and so on. Each can affect how the website appears onscreen.
Browser Software and Version. There are many different web browsers and
browser versions. Some run on only one type of hardware platform, others run
on multiple platforms. Some examples are AOL 9.0, Firefox 1.0, Internet
Explorer 5.0 and 6.0, Pocket IE, Netscape 7.2, and Opera 7.54.
Each browser and version supports a different set of features. A website
may look great under one browser and not display at all under another. How
would this impact your testing?
Browser Plug-Ins. Many browsers can accept plug-ins or extensions to gain
additional functionality. An example of this would be to play specific types of
audio or video files.
