Subject [jira] Created: (SUREFIRE-706) Global lock to serialize tests even if maven runs in parallel mode

Global lock to serialize tests even if maven runs in parallel mode

                 Key: SUREFIRE-706
             Project: Maven Surefire
          Issue Type: Improvement
          Components: Maven Surefire Plugin
         Environment: all
            Reporter: Frank Meilinger

It would be nice to serialize unit tests globally in the surefire plugin, even if maven 3
runs with parallel mode. I know that some test providers are able to do parallel testing itself
(e.g. Junit47 provider) without running maven in parallel or not. These test provider parallel
mode can be configured with surefire plugin configuration. E.g. <parallel>none</parallel>
can be used to serialize unit tests even if using the JUnit47 provider. But when running maven
3 with -T <n> option, the tests are still running in parallel, depending on the parallel
decision of maven 3. For code which is not able to run in parallel (while unit tests are running,
this will happen), this is a problem. In this case the provider option <parallel>none</parallel>
won't help. I think it would be great (and maybe easy to implement) to have a global surefire
plugin option to globally lock the surefire plugin's execute() method to serialize all unit
tests over all parallel maven builds.
