Re: Skipping test using unittest SkipTest and exit status

errors=1) 2. I find assert and raise RunTimeError also fitting my program ,please suggest whats best form unittest fixture point of view. if not self.scan: logging.error("Failed scanning ") assert False, "Class setup failed skipping test"

how to optimize the below code with a helper function

bject="baddr", offset="100", size="5", optype="set") (1) Any tips how I can optimize this i.e test case, should have a helper function that all test cases call. (2) Also note that failure.run_tool function can have variable number of argments how to handle this in the helper function? Thanks in advance Regards, Ganesh -- https://mail.python.org/mailman/listinfo/python-list
