             Summary: Ensure that test methods in different test classes use different cluster addresses
                 Key: ISPN-1953
                 URL: https://issues.jboss.org/browse/ISPN-1953
             Project: Infinispan
          Issue Type: Task
          Components: Test Suite
    Affects Versions: 5.1.3.CR1
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 5.1.3.FINAL


TestNG will start a method has a {{@Test(timeout = x)}} annotation in a separate thread. Because of this, we don't have access to the test name and we have to rely on the method name only to provide a unique identifier for the cluster.

This approach breaks down when we have a test class extending another, as all the test methods in the parent class are now duplicated. E.g. StateTransferClassLoaderFunctionalTest extends StateTransferFunctionalTest, which leads to failures like this in the test suite:

{noformat}
Cache at address testSTWithWritingNonTxThread-55146 had 3 members; expecting 2. Members were (testSTWithWritingNonTxThread-55146, testSTWithWritingNonTxThread-61383, testSTWithWritingNonTxThread-7922)
{noformat}

The solution is to force the user to provide the name of the test, e.g. by calling a method {{backgroundTestStarted(this)}} at the start of each method with a {{@Test(timeout = x)}} annotation. As a bonus, this will make it easier to search for the logs of such test methods.
