What numbers can you pass as verbosity in running Python Unit Test Suites?
Question:
The Python unittest framework has a concept of verbosity that I can’t seem to find defined anywhere. For instance, I’m running test cases like this (like in the documentation):
suite = unittest.TestLoader().loadTestsFromTestCase(MyAwesomeTest)
unittest.TextTestRunner(verbosity=2).run(suite)
The only number I’ve ever seen passed as verbosity is 2. What is this magic number, what does it mean, what what else can I pass?
Answers:
You only have 3 different levels:
- 0 (quiet): you just get the total numbers of tests executed and the global result
- 1 (default): you get the same plus a dot for every successful test or a F for every failure
- 2 (verbose): you get the help string of every test and the result
You can use command line args rather than the verbosity argument: --quiet and --verbose which would do something similar to passing 0 or 2 to the runner.
