ITestResult missing exception message + stack when tests get skipped during the Before hooks

[Ish Abbi]

Hi,

I'm using TestNG with  Selenium for executing tests. I've noticed that in case my tests fail inside the @Before hooks the tests get marked as "skipped" but I don't get any throwable object in the ITestResult instance of my @After hooks (It fails with a null pointer).

The full stacktrace + exception message is however present in the resulting testng-results.xml.

Can someone please help me with what could be the reason for this behavior? And what can be done to obtain the throwable in case my tests get skipped?

Thanks,

Ish

What version of TestNG are you working with? Can you please make sure you are using the latest released version ( 7.4.0 as of today) and try again ?

If the problem persists, please help share a sample that can be used to recreate the problem.

Thanks & Regards

Hi Krishnan,

Thank you for reaching out. I'm using the latest versions of TestNG. The issue I'm facing was present in the earlier versions as well.

I've shared the code used as a gist @ https://gist.github.com/rookieInTraining/8fae4d459514a299925d06a59090c832

Couple of things.

1. You need to use TestNG 7.4.0 (latest released)

2. You are trying to retrieve the Throwable object for a test method that was skipped, which explains why you are seeing a Null Value.

The Throwable object for a ITestResult would be populated ONLY if the test method failed. In your case your "@BeforeMethod" introduced a failure, which caused the test method to be skipped.

Thanks Krishnan for clarifying the above.

Is there any provision using which I can get the Throwable objects of the @Before hooks ?

[⇜Krishnan Mahadevan⇝]

You can try leveraging TestNG listeners instead of using "@BeforeMethod and @AfterMethod".

For e.g., IInvokedMethodListener using which you should be able to intercept the failure reasons of both test and configuration methods by inspecting the test result and if failure then querying the throwable object.

For methods that were skipped, you should be able to find out the upstream methods that caused a particular method to be skipped by checking ITestResult.getSkipCausedBy()
