Visual Studio 2017 - Test Runner - Debug Selected Tests - NUnit - Not Working

Question

When running Debug Selected Tests in Visual Studio 2017, debugger just starts briefly and shuts down with selected test turning blue icon with exclamation mark (inconclusive test).

Output window from Debug shows:

The program '[1852] testhost.x86.exe: Program Trace' has exited with code 0 (0x0).
The program '[1852] testhost.x86.exe' has exited with code 0 (0x0).

Similar happens when using Run Selected Tests command (naturally, without debugging session popping up).

Funnily, running Test -> Run -> All Tests or Test -> Debug -> All Tests works fine.

Unit tests in the project are written against NUnit 3.x framework.

Answer 1

Solution was to add missing Nuget package NUnit3TestAdapter to the unit-test project. After that both options Debug Selected Tests and Run Selected Tests started working as expected.

Install-Package NUnit3TestAdapter
