Clover

Clover is a Java code coverage analysis application that includes historical reporting, control over the coverage gathering process, command line tools, and legacy integration. Additionally, it reduces testing time by running only tests that cover the application code that was modified since the previous build. This can lead to large reductions in the amount of time you spend waiting for automated tests to complete. This plugin uses Clover Command Line Tools, which provide a set of programs used for integration with legacy build systems such as Make and custom build scripts.
