IInvokedMethodListener expects all config and testmethods to be on implementing class

[Tarun Kumar]

I am using IInvokedMethodListener of TestNG to carryout certain operations after execution of a test method -

public class MyListener implements IInvokedMethodListener {

@Override
public void beforeInvocation(IInvokedMethod method, ITestResult testResult) {
  // some magic here
}

@Override
public void afterInvocation(IInvokedMethod method, ITestResult testResult) {
  // some magic here  
}

But execution of tests using mvn test results in following errors -

java.lang.NoSuchMethodException: com.savingglobal.opsys.webui.util.MyListener.springTestContextPrepareTestInstance java.lang.NoSuchMethodException: com.savingglobal.opsys.webui.util.MyListener.springTestContextBeforeTestMethod()

and all of the configuration methods and my test methods. Am I using the listener wrong? I am on TestNG 6.9.10

Tarun,

Can you please share the complete stacktrace ? With the stubbed listener code that you shared, its difficult to guess what could be going wrong. But on the face of it, it looks like the problem is perhaps not from the TestNG listener as such but the code path that the TestNG listener is executing.

Just to confirm this, can you quickly stub out all the real code in your listener, add some sysouts and check if the sysouts are getting printed ?

Thanks & Regards

Some more debugging and found that error is from following line when I construct Method object

public void afterInvocation(IInvokedMethod method, ITestResult testResult) {

Method testMethod = getClass().getMethod(testResult.getName());
}

Since MyListener does not have springTestContextBeforeTestClass config method hence I get this error. but then 
how do I get reference of testMethod ?

The stacktrace for config method - springTestContextBeforeTestClass (and many similar stacktraces for each config method 
and eventually testMethod). 

java.lang.NoSuchMethodException: com.savingglobal.opsys.webui.util.MyListener.springTestContextBeforeTestClass()
	at java.lang.Class.getMethod(Class.java:1670)
	at com.savingglobal.opsys.webui.util.MyListener.afterInvocation(MyListener.java:34)

Tarun,

The line : Method testMethod = getClass().getMethod(testResult.getName());

is basically trying to search for a method name as returned by testResult.getName() in your listener [ getClass() within a listener would cause Java to refer to the listener class ]

If you basically want to figure out the testMethod that was invoked just before afterInvocation() was invoked you should be doing

Method method = testResult.getMethod().getConstructorOrMethod().getMethod(); //here testResult is of type ITestResult
