I am new to Gitlab CI so excuses in advanced. I have a .NET Core Api application which has xUnit tests. I wanted to make a pipeline to have two stages:
Build: Where the code compiles and checks if there are any issues.
Test. If they pass, let me know or if they fail, I would like to see which ones failed.

I am able to achieve this. The build has green/red and Test has green or red depending upon if it builds successfully. But, next to Jobs there is a Tests column in the Pipeline of GitLab and that has 0 tests inside it. In the summary of the test it also says the following:

Summary
0 tests
0 failures
0 errors
0% success rate
0.00ms
Even though in the test job it says:

A total of 1 test files matched the specified pattern.
Results File: /TestResults/TestResults.xml
Passed!  - Failed:     0, Passed:     7, Skipped:     0, Total:     7, Duration: 1 s - Eic.Test.dll (net8.0)

What am I doing wrong?

I tried reading the documentation of Gitlab and the ci file is in line with what they mention should work.
