I have a makefile for compiling a static library. This makefile has a rule for compiling a unit test suite associated with the static library. Once the test suite is compiled, a python script is invoked to run the tests and log the results. It looks like this:
unit:
$(MAKE) -C cXbase/unit
python $(TESTS_RUNNER) $(UNIT_TESTS_EXEC) $(UNIT_TESTS_LOG)
I use Python to make the tests invocation portable. Right now, everything works fine: the tests compile and the test runner is called and logs everything properly in Linux and Windows. Only, when a test fail, I would like to stop the whole make process and return an error. More precisely, I would like not to be able to make all or to make unit when a unit test fails (or many).
If a unit test fails, the Python script returns a specific exit code. I would like to be able to capture it in a portable way and have make fail if that exit code is captured.
Would you have any recommendations on how to do this? I have found nothing convincing or portable elsewhere.
Thanks
