pip install pytest-mypy-plugins
Examples of a test case:
# typesafety/test_request.yml
- case: request_object_has_user_of_type_auth_user_model
disable_cache: true
main: |
from django.http.request import HttpRequest
reveal_type(HttpRequest().user) # N: Revealed type is 'myapp.models.MyUser'
# check that other fields work ok
reveal_type(HttpRequest().method) # N: Revealed type is 'Union[builtins.str, None]'
files:
- path: myapp/__init__.py
- path: myapp/models.py
content: |
from django.db import models
class MyUser(models.Model):
pass
Running:
pytest
mypy-tests:
--mypy-testing-base=MYPY_TESTING_BASE
Base directory for tests to use
--mypy-ini-file=MYPY_INI_FILE
Which .ini file to use as a default config for tests
--mypy-same-process
Now, to help with various issues in django-stubs, it runs every single test in the subprocess mypy call.
Some debuggers cannot attach to subprocess, so enable this flag to make mypy check happen in the same process.
