I have a test project that runs locally without problem but it fails on our two build agents with the following message:
"Process exited with code -4 (Step: Run unit tests release MeasurementProgram(NUnit))"
What does "code -4" mean? Is it a TeamCity or NUnit error message? I have searched google for this particular error message but found nothing.
The build log for the failing build step looks like this:
