• Reliable GUI component lookup (by type, by name or custom search criteria)
• Support for all Swing components included in the JDK
• Compact and powerful API for creation and maintenance of functional GUI tests
• Supports Applet testing
• Ability to embed screenshots of failed GUI tests in HTML test reports

Why have I forked Fest Swing?

AssertJ Swing is a fork of FEST Swing, a great project I have used for five years and that Joel has contributed to during 3 years, so why have I forked it?

Well the main reason is, FEST Swing isn't really being continued. On 10th September, 2012 Alex announced that he stopped development and that Yvonne is going to continue FEST Swing. Unfortunately except February and March of 2013 there were no further commit activities on FEST Swing.

I think even if some developers declare Swing as dead, FEST Swing is still used a lot and the development should continue. Not only support for the next Java releases should be ensured. But there are also a lot of issues that would improve FEST Swing. Therefore we added AssertJ Swing to the AssertJ suite.

Thanks

AssertJ Swing has its roots in FEST Swing, a project I have used for 5 years, so thanks to Alex Ruiz FEST's creator!

This documentation is based on the large documentation of FEST Swing. So thanks a lot to all the original authors!
