You might need your JUnit tests to always pass for whatever reason (not naming any names :)) For this reason, just use the java agent that is produced by this project!
A JDK 1.7+ needs to be installed on your machine
This is Maven multi-module project that contains the agent module and a sample for testing it. The sample contains a JUnit test which under normal circumstances will always fail! However, when run with the agent, the tests always pass!
From the project root simply run:
$ ./mvnw package
The goal will create a java agent in ./agents/junit-agent.jar that is then used when running the tests for the sample.
The agent in then used when running the tests using the configuration than can be found sample/pom.xml
I came up with this simple project after checking out this awesome project!
