             Summary: Misleading documentation on forkCount with JUnit provider
                 Key: SUREFIRE-1171
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-1171
             Project: Maven Surefire
          Issue Type: Bug
            Reporter: Bruno Bieth


On this page https://maven.apache.org/surefire/maven-surefire-plugin/examples/fork-options-and-parallel-execution.html I can read the following:

{quote}
As reuseForks=false creates a new JVM process for each test class, using parallel=classes would have no effect. You can still use parallel=methods, though.

When using reuseForks=true and a forkCount value larger than one, test classes are handed over to the forked process one-by-one. Thus, parallel=classes would not change anything.
{quote}

However in my experience only the junit47 provider manages forked VM. The junit4 provider simply ignores the forkCount setting.
As stated in the documentation on JUnit : http://maven.apache.org/surefire/maven-surefire-plugin/examples/junit.html in order to activate the junit47 provider one must set the parallel attribute.

So on one hand the doc says that the parallel attribute is useless with forkCount but on the other hand if it's not specified, the old junit4 provider is used and forkCount isn't applied.
