Developers usually make do with manually testing their code as they're learning, but you can both save time and improve test accuracy by automating your tests. The most common tool for test automation is Simpletest, which we will cover in future videos. The less common, but more accessible tool is called Selenium IDE. Selenium is an incredibly useful tool you can use to automate browser activity in Firefox. It allows you to record your actions, modify them, and replay them. Because Selenium is browser-based, it allows you to test things like AJAX and javascript, among other things. You can then save these recordings and use them to test your module's functionality without having to test manually.

In this video, we will be demonstrating the power of Selenium to save time while developing, and to insure that as you add new functionality to your module, other things aren't breaking behind the scenes.
