I have the following typical python project file structure

packageA
   +----subpackage1
            +----classa.py
   +----subpackage2
            +----classb.py
   +----test
          +----subpackage1
                    +----classa_test.py 
          +----subpackage2
                    +----classb_test.py

I am currently trying to organize my unittests and functional tests so I can run unittests and functional tests separately using nose but also have the option to run all tests. The tests would live in packageA/test/subpackage1 and packageA/test/subpackage2.

  • What is a good way to organize the different tests? By folder (functional/ vs unit/) ? By naming convention of test class (ClassATest vs ClassAFunctionalTest)? or by naming convention of test methods (classa_foo_test vs classa_bar_functional_test)?
  • Can someone explain how nosetests’s regex matching works? The options -m, -i and -e don’t seem to run as I expect to run. Does the regex match directories (subpackage1), files (classa_test) or test classes (ClassATest) or test methods (classa_foo_test)? I am extremely confused

    My tests directory structure looks this way:

    root
  + --- tests
  |       + --- unit_tests
  |       |         + --- some_app_tests   
  |       |         + --- another_app_tests
  |       |         | run_tests.py
  |       |
  |       + --- integrate_tests 
  |                 + --- some_app_tests
  |                 + --- another_app_tests
  |                 | run_tests.py
  |       
  + --- project_root
          + --- some_app
          + --- another_app

    For each individual app I create coresponding directory with tests in unit- and integrate- directory. Each is directory is separate django project with custom settings and there’s management command used to run tests.

    Also placing tests in one directory has one nice advantage – when project is deployed, there’s no reason to deploy tests with it. So I just strip one directory and that’s all.

    (to run tests I use django-sane-testing: https://github.com/Almad/django-sane-testing )
