Description

Here is a simple testcase.

POM file:

			<plugin>
				<artifactId>maven-surefire-plugin</artifactId>
				<version>2.8.2-SNAPSHOT</version>
				<configuration>
					<includes>
						<include>**/TestSuite.java</include>
					</includes>
					<parallel>methods</parallel>
				</configuration>
			</plugin>
		</plugins>

TestSuite.java

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses(
{
	ParallelTest.class,
	ParallelTest2.class
})
public class TestSuite
{
}

ParallelTest.java

public class ParallelTest
{
	public ParallelTest()
	{
		System.out.println("ParallelTest.constructor");
	}
	
	@Before
	public void setUp()
	{
		System.out.println("ParallelTest.setUp");
	}

	@After
	public void tearDown()
	{
		System.out.println("ParallelTest.tearDown");
	}

	@Test
	public void first() throws InterruptedException
	{
		System.out.println("begin ParallelTest.first");
		Thread.sleep(1000);
		System.out.println("end ParallelTest.first");
	}

	@Test
	public void second() throws InterruptedException
	{
		System.out.println("begin ParallelTest.second");
		Thread.sleep(1000);
		System.out.println("end ParallelTest.second");
	}

	@Test
	public void third() throws InterruptedException
	{
		System.out.println("begin ParallelTest.third");
		Thread.sleep(1000);
		System.out.println("end ParallelTest.third");
	}
}

ParallelTest2.java is identical except that log output contains ParallelTest2 instead of ParallelTest.

Actual Output:

Concurrency config is parallel='methods', perCoreThreadCount=true, threadCount=2, useUnlimitedThreads=false
Running com.holdmyspot.health.server.ParallelTest
ParallelTest.constructor
ParallelTest.setUp
begin ParallelTest.first
end ParallelTest.first
ParallelTest.tearDown
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.014 sec
Running com.holdmyspot.health.server.ParallelTest2
ParallelTest2.constructor
ParallelTest2.setUp
begin ParallelTest2.first
end ParallelTest2.first
ParallelTest2.tearDown
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 1.014 sec

Results :

Tests run: 2, Failures: 0, Errors: 0, Skipped: 0

Problem: methods second() and third() are never run for either ParallelTest or ParallelTest2.
