During JavaOne 2007, I attended Chris Richardson’s talk on Minimalist Testing Techniques for Enterprise Java Technology-Based Applications. Beyond the usual JUnit and CruiseControl, he mentioned a few new interesting names: JMock, EasyMock, and Selenium. Both JMock and EasyMock are object mock-up frameworks that allow a developer to focus on unit test a module independent from others. In order to use this, a team needs to agree on interfaces among modules before creating such mock-ups. Seleium is a web application testing tool that focus on browser compatibility and functional testing. It runs within a browser and has its own IDE for test development. These are certainly interesting testing tools.
