This is mostly a place holder while we develop more content. Here are some useful links...

The Basics

Setting up Selenium IDE

1. Download/install Selenium IDE for Firefox

2. Open Selenium IDE from Firefox under the Tools pulldown menu

3. Once IDE is open, go to: Options > Options... > Locator Builders and reorder them to (from top down): id, name, link, css, ui, ...then everything else...

Ordering them like this makes for faster running tests, as finding unique elements (id, name, link) is faster (and easier to read) than hunting for them using another method. The fallback is using css selectors, as css selectors have proven to be faster than xPath.

Element Locators

A common way to find elements on a page using Selenium is xPath, however, we should use CSS selectors when possible, as the tests run faster - especially in IE. Here's some info:

Testing AJAX applications

The main things you'll need to test AJAX calls is the waitFor... commands. Here are a few of the most useful ones:

waitForCondition(script, timeout)

This is probably the most important one. Examples. Arguments:

  • script - the JavaScript snippet to run
  • timeout - a timeout in milliseconds, after which this command will return with an error

Runs the specified JavaScript snippet repeatedly until it evaluates to "true". The snippet may have multiple lines, but only the result of the last line will be considered.

Note that, by default, the snippet will be run in the runner's test window, not in the window of your application. To get the window of your application, you can use the JavaScript snippet selenium.browserbot.getCurrentWindow(), and then run your JavaScript in there

waitForVisible(locator)

Generated from isVisible(locator) Arguments:

  • locator - an element locator

Returns: true if the specified element is visible, false otherwise

Determines if the specified element is visible. An element can be rendered invisible by setting the CSS "visibility" property to "hidden", or the "display" property to "none", either for the element itself or one if its ancestors. This method will fail if the element is not present.
