# We have a fake TEST_SUITE in tests/run_all_tests which runs Phan, and check if the exit code is non-zero and the standard output is non-empty.
# This is used instead of a unit test because Phan currently caches too much state for this to be run with other unit tests, and the configuration might end up different within a unit test.
# This was moved into a separate script to stop cluttering up .travis.yml
