eCobertura is a free Eclipse plugin for Cobertura - a Java code coverage reporting tool.
eCobertura enables you to launch your applications or tests in Cobertura-covered mode directly from within Eclipse. View your source files colored according to the coverage results. Browse through the detailed coverage results in a tree view.
This plugin is based on Cobertura because Cobertura is able to measure branch coverage.
