2 Usage

3 Testing

3.1 Testing without worrying about dependencies

Run from tox to test the packaging cycle inside a virtual env, plus run all tests:

# just run tests
$ tox -e dev -- tests
# run tests, validate README.rst, run flake8 linter
$ tox -e stage -- tests

3.2 If tox is taking too long

The test framework is pytest. If you only want to run tests:

$ pip install -e .[dev,test]

3.3 Day-to-day testing

• Tests live under /tests (surprising, eh?). Mirror the directory structure of the code being tested.

• Prefix a test definition with test_ - so a unit test looks like

  def test_this_should_totally_work():

• To execute tests, from root directory: pytest tests

• For a bit more info on running tests: pytest –verbose [path]

• To execute a specific test module: pytest tests/unit/arb_test_file.py
