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
   • In Run/Debug Configuration put environment variables from prerequisites
   • For workaround "django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet." add this lines to test file before importing models:

     import django
     django.setup()
