Testing

Prerequisites

Consider next required conditions for running tests:

  • venv

    Don't forget to run it under configured venv. Look setup venv how to configure venv

  • postgres

    Due to tests make database queries the local postgres should be running.

    Run postgres:

    $ docker-compose -f docker-compose.yml up -d postgres

    For first time run migrations (it needs only for fresh images)

    (venv) $ ./manage.py migrate
  • redis Run redis:

    $ docker-compose -f docker-compose.yml up -d redis
  • build frontend

    For views tests its essential to build our frontend upfront. Hot to build front look setup-frontend section, for now just run next commands:

    $ cd frontend
    $ npm ci # or npm install
    $ npm run build

    Above commands will create required webpack-stats.json file

  • test environment variables

    DJANGO_SETTINGS_MODULE=club.settings;
    PYTHONUNBUFFERED=1;
    TESTS_RUN=da
    POSTGRES_DB=vas3k_club
    POSTGRES_USER=postgres
    POSTGRES_PASSWORD=postgres
    POSTGRES_HOST=localhost
    REDIS_DB=0
    REDIS_HOST=localhost

Run tests

Basically tests automatically runs in CI in opened PR, but if you want to run tests locally there are few ways to do it

  1. virgin shell
    $ make test
  2. venv shell
    $ source {your-venv-folder}/bin/activate
    (venv) $ ./manage.py test
    (^don't forget inject test env variables)
  3. pycharm profession edition Use django tests template out of the box
  4. pycharm common edition
    • Make sure you have set Unittest as default test runner: Settings --> Tools --> Python Integrated Tools --> Default Test Runner: Unittests Default Test Runner
    • In Run/Debug Configuration put environment variables from prerequisites Test template
    • For workaround "django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet." add this lines to test file before importing models:
      import django
      django.setup()

For more information about testing in django look well written official documentation
