Try to use with parallel test execution (Junit 5)

(Note: This feature is not working when you are using JUnit 5.3.1 parallel test execution feature.)

Any update on when you might be able to have the parallel execution work as expected. It is a pretty big need to make this an effective retrier

Hey! I was investigating time to implement this feature - but I haven't already found a solution. All parallel execution behind the science (deep in JUnit core). I will try to research the solution else in February. Now I don't have free time.

Thanks! Someone else on my team came up with a solution that works, if you simply add the following annotation to all parallel tests it will run in parallel as expected!
@ResourceLock(value = SYSTEM_PROPERTIES, mode = READ_WRITE)

This does have some limitations as it means any repeated test will only run in serial, the upside is that any test that is not repeated or a normal parameterized test will run in parallel, so better than nothing however still a ways to go to get full parallelization.

This man implements parallel test execution. Will grab it or @foxfortune you can do it.

I pulled it down and tried testing it locally but I still see the tests not retrying and only running once when running in parallel. I sent Tofel an email to see if there is something I am missing...

Hi, did you manage to handle this issue? In my case, it works for parallel tests execution on version 2.1.3 but at some point, it stops and In case of fail I get 1 run in status skipped.
I don't have a clue why because nothing related to rerun or JUnit config was changed.
I try to debug Gradle build and looks like TestExecutionExceptionHandler is not invoked in case of failure.

This fork behaves the same for concurrent tests in my case. (only one run in case of failure in status skipped).

For both rerunner impl annotating class that contains @RepeatedIfExceptionsTest with :
@ResourceLock(value = SYSTEM_PROPERTIES, mode = READ_WRITE)
or
@execution(ExecutionMode.SAME_THREAD)
or setting properties
systemProperties['junit.jupiter.execution.parallel.mode.default'] = 'same_thread'
systemProperties['junit.jupiter.execution.parallel.mode.classes.default'] = 'concurrent'

helps to resolve, so you should force to run all tests within the class in the same thread.

The mentioned fork is not available anymore. Is there any chance that this library will support concurrent execution soon?

Is there any updates on this?
