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.

Does anyone know where NUnit console exit codes meanings can be found?

Answer 1

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!
