Python unittest and discovery

Question

I have directories, which contain files named like: test_foo.py

Each file is a test case.

I would like to

1. Run all the tests in a direc

Answer 1

Once you have discovered tests, you can run them with a test runner.

For Python 2:

import unittest2
loader = unittest2.TestLoader()
tests = loader.discover('.')
testRunner = unittest2.runner.TextTestRunner()
testRunner.run(tests)

For Python 3:

import unittest
loader = unittest.TestLoader()
tests = loader.discover('.')
testRunner = unittest.runner.TextTestRunner()
testRunner.run(tests)

Running the above code will print the test results to standard out.
