die only when invoked directly
Review Request #1953 - Created March 20, 2015 and submitted
- die should die only when invoked directly
This was causing PythonEval to blow up with exit 1 when running
./pants test tests/python/pants_test/python::... there are other errors in there due to negative-test helpers (which IMO, should be inlined into their respective files), but this is a tactical fix.
