Is it safe to remove the TUnit ThrowListener from Trace.Listeners ?

[ssc218]

TUnit registers a ThrowListener implemented here as a TraceListener.
When calling for example Debug.Fail this listener throws a TUnit exception, which causes the test to fail.

I want to suppress this exception so that my test passes, even when Debug.Fail is called. One way to achieve this is to simply remove the ThrowListener from the global Trace.Listeners collection.
Can I do this without affecting other TUnit behavior, and is there a better way to customize the behavior of calls to the Debug class?

It was added because the default behaviour was calling Environment.Exit I believe and terminating the whole test session.

If you add your own throw listener that mitigates this then it should be fine

Thanks for the fast answer.

Just fyi: An instance of DefaultTraceListener is still registered in addition to the TUnit ThrowListener. This listener does basically nothing when running the tests 🤷‍♂️

EDIT:
The default listener is still registered and indeed causes the test exe to exit with an error code (like it is expected from Debug.Fail) which is treated as no test having been run at all. However, Visual Studio does not really show this in its UI except in the status bar at the bottom, which leads to the Visual Studio test explorer giving the impression that all tests ran.
