JaCoCo a coverage analysis tool. It runs as a JVM Agent and therefore does not require offline instrumentation.

JaCoCo is an EPL-licensed, open-source code coverage analysis tool. It runs as a JVM Agent and therefore does not require offline instrumentation.

Compared to Cobertura, it has lower runtime overhead but less precision. It is unable to record hit counts, it only records red/green, however it can show coverage on class, method, line, complexity, branch and instruction level. It also has the ability to merge the results of multiple analyses when generating a report.
