I have a project with nearly 500 individual tests in around 200 test classes. Some of these tests don't do a great job of tearing down their own state after they're finished, and in Eclipse this results in some tests failing. The tests all pass when running the test suite from the command line via Ant.
Can I enable 'test isolation' somehow in Eclipse? I don't mind if it takes longer to run.
Long term, I will clean up the misbehaving tests, but in the short term I'd like to get the tests working.
Run-> Run Configurations -> JUnit, select your run configuration, then you have an arguments tab to specify JVM or program arguments. You can then duplicate this run configuration to use for other tests.
Once parallel test execution property is enabled, the JUnit Jupiter engine will execute tests in parallel according to the provided configuration with declared synchronization mechanisms.
If you use Ant in Eclipse, you can set the JUnit task to fork a new JVM process for each test, providing isolation.
