I have a C# test project with an API integration test that only runs successfully when the Configuration Manager is set to “Release” and I execute the test in Release mode. The test fails to run in Debug mode. ( simply skip tests without any reason (1. picture) ).

Here are a few points I have checked already:

• Verified that there are no #if DEBUG preprocessor directives affecting the test.
• Checked that both configurations build without errors.
