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.
