Parallelize test runs

[ncd7]

Could we add a feature for the runner to parallelize test execution (using an executor service based on the available core or whatever policy you deem appropriate)?

I've about 1000 parametrized tests in a single module and while intellij is showing me a total runtime of about 4s, in reality it takes more like 40-50s (i suspect the startup/shutdown harness work, class loading, etc, are at play). These are pure unit tests and do not access outside resources so they are definitely CPU bound and CPU utliziation is only about 30% while running. Suggestions very welcome. Thanks.

I found this https://github.com/MichaelTamm/junit-toolbox so now trying to figure out if i can use @Rule so i can make junitparams run with the parallel runner...

EDIT: the only reference to using rules I found is here https://github.com/Pragmatists/JUnitParams/wiki in an entry for Jun 14, 2011: Release 0.3.2 which refers to the docs, so going to try to dig in there.

Actually I just saw this: https://github.com/Pragmatists/JUnitParams/issues/13 .... not looking promising. :(

Any solutions on how to run parameterized tests in parallel? It takes me around 5 sec to run one iteration of test. Running many iterations is time consuming .

We were trying to implement it but with no luck. To be honest I think we'll not implement it. Any support on it from you, who are interested in solution, will be appreciated. Maybe together we will find some quite simple solution for it.

Hi,

I'm interested in working on this. Perhaps we can discuss if this is possible and what are the options.
