84. Python unit testing frameworks: Nose, Pytest 2015-02-13

    Python's built-in unittest module is quite cool, but a bit limited and way too verbose (read: it's quite not easy to incite developers to write unit tests)

    I'm currently looking for more dev-friendly solutions, the key points being:

    • writing test code should be easy and straight-forward -keep the focus on "what to test" instead of "how to transcribe a process to a test"
    • parallelization! -we, spoiled developers, should make good use of our way-too-many-cores build machines...
    • complete feature set!
      • we don't want to just run tests...
      • coverage reports (find dead/weak/untested code sections)
      • output formatting (JUnit-XML seems to be quite a common format out there)

    There seem to be 3 solutions in Python:

    • stock unittest + project-dependent customizations / test helpers
    • nosetests
    • py.test

    And 2 ways of gettings things done:

    • keeping things stock: no external dependency, project-specific implementation...
    • using a test framework: one more module in your (test) virtualenv, more concise tests, more features (// run, code coverage, etc.)
