I'm using JUnit 4.4 and Maven and I have a large number of long-running integration tests.
When it comes to parallelizing test suites there are a few solutions that allow me to run each test method in a single test-class in parallel. But all of these require that I change the tests in one way or another.
I really think it would be a much cleaner solution to run X different test classes in X threads in parallel. I have hundreds of tests so I don't really care about threading individual test-classes.
Is there any way to do this?
Use maven plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.7.1</version>
<configuration>
<parallel>classes</parallel>
<threadCount>5</threadCount>
</configuration>
</plugin>
</plugins>
</build>
