根因分析

Pytest 无法找到 fixture，因为它未定义、未导入或在测试函数中拼写错误。

English

Pytest cannot locate a fixture because it is not defined, imported, or spelled incorrectly in the test function.

generic

解决方案

  1. 95% 成功率 Define fixture in conftest.py at the appropriate level 
    # conftest.py
@pytest.fixture
def db_session():
    return create_session()
  2. 90% 成功率 Use @pytest.fixture decorator in test file 
    @pytest.fixture
def db_session():
    return create_session()

无效尝试

常见但无效的做法:

  1. Defining fixture in the same file but with wrong name 70% 失败

    Fixture name must match exactly; typos cause not found errors.

  2. Using fixture from conftest without importing 50% 失败

    conftest fixtures are automatically available, but only if conftest is in the correct directory.
