Open Source Groovy Logging Software

A Gradle plugin for printing beautiful logs on the console while running tests. The plugin registers an extension called testlogger (all lowercase and one word) at project level as well as for each task of type Test. By default, the showExceptions flag is turned on. This shows why the tests failed including the location of the failure. Of course, you can switch off this slightly more verbose logging by setting showExceptions to false. Just like Gradle itself, by default only the last frame that matches the test class's name in a stack trace is printed. For vast majority of cases, that is sufficient. Sometimes, it is useful to remove this filtering in order to see the entirety of the stack trace.
