Root Cause

Fixture name is misspelled, defined in a conftest.py outside the test's directory scope, or not imported because the plugin is not installed.

generic

中文

Fixture 名称拼写错误，定义在测试目录范围之外的 conftest.py 中，或者因插件未安装而未导入。

Workarounds

  1. 95% success 
    Create `tests/conftest.py` with `@pytest.fixture
def db_session(): ...` and ensure tests are under `tests/`.
  2. 90% success 
    `pip install pytest-django` then in pytest.ini: `[pytest]
DJANGO_SETTINGS_MODULE = myproj.settings`

Dead Ends

Common approaches that don't work:

  1. 40% fail

    Duplicates fixture logic across many test files and defeats the purpose of shared fixtures.

  2. 90% fail

    Shadows a built-in pytest fixture and causes unexpected behavior in other tests.
