NullPointerException in ITestResult when failed @BeforeClass method

[Алексей Панащенко]

Hi!

I use TesNG and I created my Listener. In this Listener I implemented IInvokedMethodListener2 and @Override beforeInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult), afterInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult).

In afterInvocation() I catch exeption and i see problem, if my test failed in @Test method -  iTestResult.getThrowable() returned exeption, but if my test failed in @BeforeClass method - iTestResult = null and system freezes. Maybe, need change returned result when test filed in @BeforeClass method.

The afterInvocation() gets invoked both for @Test methods and also for configuration methods as well.

I don’t think the ITestResult object is NULL in this case. I believe that getThrowable() is returning a null and your code seems to be doing something with it.

Can you please try creating a simple example that can show this problem ?

Here's a simple example I tried :

package organized.chaos;

import org.testng.annotations.Listeners;

import org.testng.annotations.Test;

import org.testng.annotations.BeforeClass;

@Listeners({ MyMethodListener.class, MyConfigMethodListener.class })

public class MySampleTest {

    @Test

    public void f() {

        System.out.println("Hello world");

    }

    @BeforeClass

    public void beforeClass() {

        throw new RuntimeException("Hi am an exception");

    }

}

package organized.chaos;

import org.testng.IInvokedMethod;

import org.testng.IInvokedMethodListener;

import org.testng.ITestResult;

public class MyMethodListener implements IInvokedMethodListener {

    @Override

    public void beforeInvocation(IInvokedMethod method, ITestResult testResult) {

    }

    @Override

    public void afterInvocation(IInvokedMethod method, ITestResult testResult) {

        if (testResult.getThrowable() != null) {

            System.out.println(":::: " + testResult.getThrowable().getLocalizedMessage());

        }

    }

}

package organized.chaos;

import org.testng.IConfigurationListener;

import org.testng.ITestResult;

public class MyConfigMethodListener implements IConfigurationListener {

    @Override

    public void onConfigurationSuccess(ITestResult itr) {

    }

    @Override

    public void onConfigurationFailure(ITestResult itr) {

        System.out.println(">>>> " + itr.getThrowable().getLocalizedMessage());

    }

    @Override

    public void onConfigurationSkip(ITestResult itr) {

    }

}

Output :
