Testing web applications is not only based on unit and functional tests for the server-side (PHP, Java) and client-side (JavaScript) components, but also on end-to-end tests like the ones performed with Selenium. Selenium is capable of driving a real browser like Firefox in the same way a user would do, letting you express a test with a series of page to load, element selections, clicks and typed characters. [...] In this tutorial, we'll experiment with the Android Driver and set up a couple of tests to run inside an Android virtual device.

He walks you through the basic setup of an Android environment (based on the Android SDK) and how to start up the Android driver installed from the Selenium site. An example test is included, showing how to make a request for a test page and checking its title as well as checking that the input from the "keyboard" is successful.

After trying out Selenium 2, it was natural for me to look for its support in PHP code; however, there isn't an official PHP Api distributed on Selenium's website. I tested all the PHP bindings I could find to see which is the best choice today.

He tried out a few different technologies:

• PHPUnit_Selenium
• Facebook's php-webdriver
• the php-webdriver-bindings project
• WebDriver-PHP

The finishes the post with a quick summary for each of the offerings including strengths each has and situations where you might want to use them.
