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?

• Shell
• Maven
• Gradle
• Ant
• Eclipse
• IntelliJ
• NetBeans

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");
    }
}

Root cause of this issue was because of this PR #3060

@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!
