I was looking for a code viewer designed to test live Java applications, mostly web applications running inside an application container such as Tomcat. Of course, there are a number of decent tools for receiving automatic unit test coverage reports, but my goal is more like real-time learning that an unfamiliar Java application, for example. with a certain user interaction.
The Java Eclipse debugger (with JPDA for remote debugging) is really useful, but only if you are already familiar with the architecture of the application. And theoretically, I could take some coverage tool and set it up to automatically update static HTML coverage reports every two seconds, but this is far from optimal.
For Adobe Flex, FlexCover does exactly what I want by providing a coverage viewer tool that visualizes coverage in near real time and is relatively easy to set up, at least for those who know this stuff. So, is there a simple, easy to configure GUI tool, free or not free, for Java?
