Rider: when using TUnit, Test Explorer > Jump to Source does not work

the in-test context menu items for Unit Test are also disabled:

AI Unit Test generation does not support Microsoft.Testing.Platform (TUnit in my case) either:

 

Hello, JoyRider ,

Jump To Source and context menu options are already available in the latest Rider 2024.3 EAP build. Regarding the Create Unit Test feature, I have created a new feature request: RSRP-499140 Support creating TUnit tests via Create Unit Test feature. Kindly upvote the request to indicate your interest.

Ivan Skorikov I am using JetBrains Rider 2025.1.2 with TUnit and double click on unit tests or Jump to Source (F4) does not work. It won't do anything
 

Martind I've tried this in the latest Rider 2025.3.0.2 + TUnit 1.2.11, and it works well for me. Could you please try upgrading Rider and verify if the issue persists? 

Thanks,

Tom

Tom Luo I've just tried with 2025.3.0.2 and TUnit 1.2.3 and later upgraded to 1.2.11, same result, it doesn't work.
 

There are also issues with Rider and TUnit regarding how it displays tests, but I saw there was another bug reported for that. See youtrack.jetbrains.com/projects/RIDER/issues/RIDER-131600/TUnit-tests-not-grouped-by-namespace-in-test-explorer

I wouldn't be surprised if both are related due to Rider being unable to retrieve the correct path to jump onto, when tests are inside some nested namespace.

Here's a screencast Recording 2025-11-24 133028.mp4

I confirm the problem is with nested tests in TUnit. So it's probably related to the other bug I mentioned.

Try the following to reproduce it under a TUnit test Tom Luo 

This works well as expected

public class Tests
{
    [Test]
    public void StandardTest()
    {
        Console.WriteLine("This is a basic test"); 

    }
}

This will be discovered properly and executed, but it has issues showing hierarchy (the static class is not showing as a parent) and jumping to source (it won't open the test source code)

public static class Parent
{
    public class Tests
    {
        [Test]
        public void FunnyTest()
        {
            Console.WriteLine("This is a funny test that runs but cannot jump to source");
        }
    }
}

Martind Thank you so much for the repro steps of the issue. It's a great help to us in investigating this issue. I have successfully reproduce the issue. 

I haven't found a known issue for this. For better tracking, I have created a new issue on our issue tracker: RIDER-133029 Jump to Source does not work for TUnit tests in nested class. You can upvote and subscribe to receive updates. 

Thanks again for your efforts in reporting this issue to us.
