Global lock to serialize tests even if maven runs in parallel mode
------------------------------------------------------------------
Key: SUREFIRE-706
URL: http://jira.codehaus.org/browse/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.
