How do I run all tests (unittest.TestCase) from a python file in a script?
I've tried using nose but it always seems to run the test discovery. All I want is to import a module, give some function a path and get the test results back, any suggestions?
At the bottom of your test script put
if __name__ == '__main__':
unittest.main()
Then just call your file as normal
$ python my_test_script.py
Optionally, if you want to use nose or pytest, you can just give it the name of the script you want to run, it will still do discovery, but only on that one file.
$ nosetests my_test_script.py
$ py.test my_test_script.py
If you're running nose from inside python, you can use nose.run()
my_script.py
import nose
nose.run()
By default, it will use the arguments you pass to the script, so if you only want to run a single test_script
$ python my_script.py /path/to/test_script.py
Or, you can pass the arguments directly inside your script
nose.run(argv=[__file__, '/path/to/test_script'])
module 'unittest' has no attribute 'run'
nose will discover plain unittest-style tests. My first example shows how to use unittest via unittest.main(), though it offers far fewer options than discovering/running tests with nose.
