using Maven surefire, I'm unable to fork parallel test execution. That is, each of my test cases hs to run in a serapate JVM, hence the forking. In addition, I want my test cases to run in parallel. the first part is working without problem: I'm able to run each test case in its own JVM. the second part, however is still a challene for me. I haven't managed to get the paralle execution of test cases working. Here is how my plugin declaration look like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.5</version>
<configuration>
<parallel>methods</parallel>
<forkMode>always</forkMode>
<argLine>-Xms512m -Xmx512m</argLine>
</configuration>
</plugin>
I've tried both methods and classes but haven't see any parallelization. My JUnit version is 4.7 as shown by the depency declaration:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.7</version>
<scope>compile</scope>
</dependency>
Any help would be much appricated.

I think that you are supposed to use the threadCount
parameter when using the parallel
mode:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.6</version>
<configuration>
<forkMode>always</forkMode>
<argLine>-Xms512m -Xmx512m</argLine>
<parallel>methods</parallel>
<threadCount>4</threadCount>
</configuration>
</plugin>
