Parallelizing via Free Style Jobs Fails

[mfuchs]

When I parallelize via the free style jobs no exclusion files are created.
This leads to all tests running on all nodes.

I can reproduce this behaviour both on my private Jenkins instance and using the demo.

Steps to reproduce:

• Install the demo, following the docker steps described here
• Run the main
• After main finishes run it again.

Expected results:

• The second time main is started its 400 tests are split amongst executors, reducing the total execution time.

Actual result:

• All tests were run on the 5 started executors, leading to 2000 tests run in total.

I found the issue:
(!) You need to add a FileParameter to the child job.
For example given that you configured the parallel-test-executor to create a "myexclusions.txt" the you need to add a File Parameter "myexclusions.txt" to the job called by the parallel-test-executor plugin.

I think the WIKI description as well as the demo should be updated to reflect that.

Thanks @mfuchs !
I was struggling with this plugin for too long until I read your issue.

I agree, the current WIKI is misleading
