In unit +tests, we test the actual code implementation. In integration tests, we test +``build`` on a few real world projects; this is mostly a sanity test. + +Integration tests take a long time to run, and are not very helpful tracking +down issues, so they are **disabled by default**. They can be enabled by passing +either ``--run-integration`` or ``--only-integration`` arguments to pytest, +where the latter will disable the unit tests and only run the integration ones. +Even though these tests are disabled by default, they will be run in CI, +where test suite run durations are not a big issue. + +To run the test suite we use ``tox``, which automates running the test suite on +different environments: + + +.. code-block:: console + + tox + + +You can find out more about how to run ``tox`` and its arguments in the +`tox documentation`_. + +We have a fairly large environment matrix. We run tests for all supported Python +versions and implementations, and with the module being invoked from path, +sdist install, or wheel install. Additionally, we have an environment for type +checking, and one to produce the documentation. There are some other extra +environments, like checking the code with the minimum version of each +dependency. + +Some examples commands for this project: + - Run type checking: ``tox -e type`` + - Only run unit tests against Python 3.9: ``tox -e py39`` + - Run both unit and integration tests: ``tox -- --run-integration`` + - Only run integration tests: ``tox -- --only-integration`` + - Only run integration tests with parallel tasks: ``tox -- -n auto --only-integration`` + - Only run unit tests against Python 3.9 with the module installed via wheel: ``tox -e py39-wheel`` + + +We have CI testing, where we the test suite across all supported operating +systems, and have test coverage reports. + + +.. _tox documentation: https://tox.readthedocs.io/ -- cgit v1.2.3
