[jira] (SUREFIRE-799) Allow test parallelisation when forkMode=always

["Kristian Rosenvold (JIRA)" <ji...@codehaus.org>]

    [ https://jira.codehaus.org/browse/SUREFIRE-799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=285537#comment-285537 ] 

Kristian Rosenvold commented on SUREFIRE-799:
---------------------------------------------

This is a cool patch;) It needs a few minor modifications; I think the regular "threadCount" parameter should be used, and the forkMode should be "perthread".

It also needs an integration test, you should be able to modify (or make a new project based on)
surefire-integration-tests/src/test/resources/runorder-parallel and a test implementation in XmlReporterRunTimeIT.

(I think you can just modify the existing to accept forkMode as a -D parameter instead of hard-coding)

I will be releasing 2.11.1 soon, but I'll schedule this patch for 2.12 if you fix this stuff.

> Surefire already allows:
> - forking
> - parallelization within a JVM
> Mixing both features would mean forking multiple JVM instead of only one.
> It would allow to parallelize tests that need to be executed in a separate JVM (i.e.: with forkMode=always). Usually these tests take longer than the simple ones. In our case, 40% of the tests are executed in 4 minutes, the other 60% need two hours. So it's obviously more interesting to parallelize the former, but these ones need to fork.
