EMMA is a Java-built code coverage tool that runs on the command line and is used to analyze a JAR’s or source code’s files through its main class.
EMMA does class, method, line, and block coverage types. This efficient testing of the code, verifies which functions and lines are being executed and which conditional ways are not being tested.
This plugin calls the EMMA tool via command line and passes the user-provided parameters.
