About JaCoCo
JaCoCo is a code coverage library for Java, and EclEmma is the Eclipse plugin built on it. Together they show which Java code your tests run.
What it does
EclEmma adds a Coverage launch mode to Eclipse, so JUnit, TestNG and other launches can collect coverage data. Results appear in a Coverage view with summaries that drill down to method level, and covered lines are highlighted in the Java source editor. The plugin does not require changes to your projects or any other setup.
