How to Solve Nullpointer exception in TestNG with dependsOnGroups

Question

I am planning to implement dependsOnGroups and Groups concept of testNG in my POM selenium framework. So I have created a POC with simple code and found nullpointer exception while run.

Code:

public class TestNGDependsOnMethodsExample {

@BeforeMethod (alwaysRun = true)
public void before(){
    System.out.println("Before Method ");
}


@Test(priority=0 , groups={"a"})
public void firstTest() 
{

    Assert.assertEquals("1","1");
    System.out.println("firstTest");
}

@Test(priority=1 , groups={"b"})
public void secondTest() 
{
    Assert.assertEquals("Pass","Pass1111");
    System.out.println("secondTest");
}

@Test(priority=2 , dependsOnGroups={"a","b"} ) 
public void thirdTest() {
    System.out.println("thirdTest");
}

@Test(priority=3, groups={"c"},alwaysRun = true)
public void fourthTest() {
    System.out.println("fourthTest");
}

}

Exception :

java.lang.NullPointerException at org.testng.remote.strprotocol.TestResultMessage.(TestResultMessage.java:127) at org.testng.remote.strprotocol.TestResultMessage.(TestResultMessage.java:148) at org.testng.remote.strprotocol.RemoteTestListener1.onTestSkipped(RemoteTestListener1.java:78) at org.testng.internal.Invoker.runTestListeners(Invoker.java:1788) at org.testng.internal.Invoker.runTestListeners(Invoker.java:1780) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1103) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:125) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:109) at org.testng.TestRunner.runWorkers(TestRunner.java:1147) at org.testng.TestRunner.privateRun(TestRunner.java:749) at org.testng.TestRunner.run(TestRunner.java:600) at org.testng.SuiteRunner.runTest(SuiteRunner.java:317) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:312) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:274) at org.testng.SuiteRunner.run(SuiteRunner.java:223) at org.testng.SuiteRunnerWorker.runSuite(SuiteRunnerWorker.java:52) at org.testng.SuiteRunnerWorker.run(SuiteRunnerWorker.java:86) at org.testng.TestNG.runSuitesSequentially(TestNG.java:1039) at org.testng.TestNG.runSuitesLocally(TestNG.java:964) at org.testng.TestNG.run(TestNG.java:900) at org.testng.remote.AbstractRemoteTestNG.run(AbstractRemoteTestNG.java:132) at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:230) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:76)

@DhavalAtri What version of TestNG are you working on? – Krishnan Mahadevan Aug 24 '18 at 04:10 — Krishnan Mahadevan, Aug 24 '18 at 04:10

By making a new project same code works fine without no NullPointerException. TestNg 6.9 & 6.9.9 having some issue i.e. testng-failur.xml is not generated properly. Or testng-failur.xml contains pass test methods.
