The Maven-Grester plugin is a Maven2 plugin for Jester, the JUnit tester tool. It enables Jester to be executed at any valid Maven lifecycle phase in a Maven Project. It saves developers from constructing cumbersome Java classpath entries on the commandline every time they need Jester to run against JUnit Tests in the project. It can also help to dispense with a suite of scripts that may have been written to handle complex Java classpath executions for Maven projects.
TRex is a tool to help maintain test suites written in the standardized Testing and Test Control Notation (TTCN-3). It provides IDE functionality for the TTCN-3 core notation and supports the assessment and automatic restructuring of TTCN-3 test suites by providing suitable metrics and refactorings.
jf-unittest is a C++ unit test framework modeled after the way the Python unittest module is used in the Confix test suites. It was written out of frustration with the existing unittest frameworks. As such, it contains no bloat: no GUI with colorful progress bars, no dependencies on any other packages.
The Google Singleton Detector, or GSD, is a tool which analyzes Java bytecode and detects the use of Singletons. It's not quite as simple as that, however. First, GSD doesn't only detect singletons; it detects four different types of global state, including singletons, hingletons, mingletons, and fingletons. Second, it outputs a graph with all these different types of static state highlighted, and shows all the classes that are directly dependent on them. The point of this tool is to allow you to see all of the uses of global state inside a project, as well as how they are all interrelated.
