Does anyone know where to find NUnit console exit codes meanings?

Question

I am getting error message from my MSBuild:

"nunit-console.exe" exited with code -100.

Where can the meaning of the NUnit console exit codes be found?

Answer 1

Error code -100 stands for UNEXPECTED_ERROR

static ConsoleUi() {     OK = 0;     INVALID_ARG = -1;     FILE_NOT_FOUND = -2;     FIXTURE_NOT_FOUND = -3;     TRANSFORM_ERROR = -4;     UNEXPECTED_ERROR = -100; } 

EDIT: Additional information from a thread on the NUnit-Discuss google group:

Additionally, positive values give a count of failed tests in the run.

The -100 return code is a catch-all, usually indicating an unhandled exception in your application or test. It should normally come with a stack trace.

Answer 2

A minor update as of NUnit v3, the TRANSFORM_ERROR code appears to have been removed.

The full list now stands as:

OK = 0; INVALID_ARG = -1; INVALID_ASSEMBLY = -2; FIXTURE_NOT_FOUND = -3;       //Reserved, but not in use since v3.0 INVALID_TEST_FIXTURE = -4;    //From v3.4 UNEXPECTED_ERROR = -100; 

The source for this is currently located here.

UPDATE: Five years on, we finally documented these. Hooray!
