ITestNGListenerFactory is broken and never invoked

[RiJo]

TestNG Version

7.10.2

Worked as expected in 7.8.0

Expected behavior

When a ITestNGListenerFactory implementation is registered via @Listeners annotation, ITestNGListenerFactory#createListener should be invoked before any @Test annotated methods are invoked.

Actual behavior

ITestNGListenerFactory#createListener is never invoked.

Is the issue reproducible on runner?

Test case sample

1. Factory is part of test class:

   @Listeners(FactoryListenerTest.class)
   public class FactoryListenerTest implements ITestNGListener, ITestNGListenerFactory {
   
   @Override
   public ITestNGListener createListener(Class<? extends ITestNGListener> listenerClass) {
       // Never invoked
       System.out.println("FactoryListenerTest.createListener");
       return null;
   }
   
   @Test
   public void test() {
       System.out.println("FactoryListenerTest.test");
   }
   }

2. Independent factory

   
   public class CustomFactory implements ITestNGListener, ITestNGListenerFactory {
   
   @Override
   public ITestNGListener createListener(Class<? extends ITestNGListener> aClass) {
       // Never invoked
       System.out.println("CustomFactory.createListener");
       return null;
   }
   }

@Listeners(CustomFactory.class) public class FactoryListenerTest {

@Test
public void test() {
    System.out.println("FactoryListenerTest.test");
}

}

@RiJo - Until this issue is fixed, can you please try adding

<properties>
   <property>
      <name>listenerfactory</name>
      <value>your.fully.qualified.classname.goes.here</value>
  </property>
</properties>

This should ensure that your listener factory gets invoked when you run your tests using maven.

For running tests via intellij you can set this configurmation via the Test runner params

Thanks for the quick response!

It is not possible for me to add custom parameters and/or properties as the TestNG tests are part of a larger system. I will stay on version 7.8.0 until the issue has been addressed. Thanks!
