Re: Issue with running junit tests in parallel

[akhilhingane]

Hi Kristian,

I read in some other thread, that you also fixed some concurrency issues
with surefire-junit in 4.8.1. Could that be a reason for the same test class
to be picked simultaneously by two forked test runners.

Regards,
Akhil

Try; in this order:

A) Use mvn help:effective-pom and analyze your surefire configuration
and see if you have multiple executions

B) Run
mvn -X clean install
cd target/surefire
grep classnameyouthinkisbeingruntwice *

The folder you are in contains all the specifications used to start
the forks, if the same class has been run multiple times, it
will be repeated in multiple files. You should find the class at least once ;)

As you mentioned, the classes which are picked up twice are indeed present in
two files under target/surefire

Re: Issue with running junit tests in parallel

I ran 'mvn clean install'. But I still see that some test cases are being
picked up by more than one parallel runners. This occurs randomly. Can there
be some issue with the junit provider? 
The configuration for the provider

Issue with running junit tests in parallel

[akhilhingane]

Hi,

   I am using maven-surefire-plugin 2.12. I intend to run test classes in
parallel and fork per test class; for which the relevant settings are as
follows. 

forkModeperthread/forkMode
parallelclasses/parallel
threadCount2/threadCount
perCoreThreadCountfalse/perCoreThreadCount


I see that the same test class is picked twice. Is the combination of above
configuration properties incorrect?

Regards,
Akhil

The configuration looks correct; make sure you run mvn clean install;
maybe you have some earlier versions in target.
