Erlang Common Test Continuous Integration

Common Test is a well thought out integration testing framework for Erlang. If you
are not using it you probably should be. However, it has one fault. It
does not return non-negative exit status’ to the caller when the tests
fail. This is a major oversight, and it makes it difficult to use as
part of a continuous integration scheme or in a make based build
system.

The long term fix is for the OTP folks to resolve the issue in the
ct_run command. To that end I have filed a bug report with the
Erlang folks. In the short term, though, we need this behaving
correctly. After much twiddling around with different solutions and
conversions on the erlang-questions list. This solution finally popped
out of a conversation with Lukas Larsson. Basically, we use the old
unix standby of awk.

    ct_run -dir tests  ... | awk "/FAILED/{exit 1;}/failed/{exit 1;}/SKIPPED/{exit 1;}"

Where ... is replaced with your additional options. Its not the best
solution on the planet, but it is the simplest one that I found that
works consistently.
