Abbot is a framework for testing Java GUIs. It lets you launch an application or GUI component, play back user actions on it, and examine its state. Tests may be coded or scripted. The editor supports recording user actions into a script, exploring the component hierarchy, running the script, and other features you'd expect from a script editor. Test scripts are JUnit extensions.
Coverlipse is an Eclipse 3.x plugin for code coverage visualization of JUnit Tests. Supported coverages include block coverage and all-uses coverage (Data Flow Analysis). Configuration is done in the Eclipse way. Result feedback is given in specialized Views and directly in the Java Editor.
MoMEUnit is an instance of the xUnit architecture for unit testing of J2ME applications. It is derived from the JUnit framework. It is only CLDC 1.1 compliant. It overcomes the lack of a reflection API in the J2ME MIDP API and supports main features of the JUnit framework such as ease of development and running of tests, sharing of fixtures among different tests, the ability to perform simultaneous test runs, and much more. The results of tests are displayed with a progress bar, statistics, and lists of failures or errors with detailed messages for each test.
