Run tests in parallel with surefire and testng

Question

I am experimenting how to run tests in parallel with maven surefire and testng. However, the configuration seems not very straightforward and I can't make it work. Below are my dummy tests.

@Log4j
public class DummyTest {
    @Test
    public void test_1() throws InterruptedException {
        log.info("test 1 started");
        Thread.sleep( 3000 );
        assertTrue(true);
        log.info("test 1 ended");
    }

    @Test
    public void test_2() throws InterruptedException {
        log.info("test 2 started");
        Thread.sleep( 5000 );
        assertTrue(true);
        log.info("test 2 ended");
    }
}

//------------------------------------
public class Dummy2Test {
    @Test
    public void test_1() throws InterruptedException {
        log.info("test 1 started");
        Thread.sleep( 3000 );
        assertTrue(true);
        log.info("test 1 ended");
    }

    @Test
    public void test_2() throws InterruptedException {
        log.info("test 2 started");
        Thread.sleep( 5000 );
        assertTrue(true);
        log.info("test 2 ended");
    }
}

And this is my surefire configuration:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.17</version>
            <configuration>
                <parallel>all</parallel>
                <threadCount>10</threadCount>
            </configuration>
        </plugin>

The tests are essentially running sequentially. Here are logs as evidence:

Results :

My intention is to run all tests (down to method level) in parallel. So, how can I achieve that?

I don't think all is an option for TestNG. Try with <parallel>methods<\paralell> if you want all to testcases to be executed in parallel.

I tried that. Unfortunately, it is not working very well. In any case, I have solved my problem by having a testng.xml where I specify parallel strategy. – JBT Oct 16 '14 at 17:46
So without a testng.xml , we cannot run the tests in parallel? I did try out the sample code and it worked fine for me without including a testng.xml file. I was able to run the test methods all in parallel. I tried with surefire 2.21.0 version and testng 6.8.21 – lostintranslation Apr 20 '18 at 11:27
