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.

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.
