根因分析

在 @pytest.mark.usefixtures 中指定的夹具名称在任何 conftest.py 或测试文件中都不存在。

English

The fixture name specified in @pytest.mark.usefixtures does not exist in any conftest.py or test file.

generic

解决方案

  1. 95% 成功率 Define the missing fixture in the test file or conftest.py. 
    @pytest.fixture
def nonexistent_fixture(): return 'value'
  2. 90% 成功率 Correct the fixture name to match an existing fixture. 
    @pytest.mark.usefixtures('existing_fixture')

无效尝试

常见但无效的做法:

  1. Adding a fixture with the same name but wrong scope 60% 失败

    The fixture must be defined and accessible; scope mismatch may still cause errors.

  2. Removing the usefixtures marker entirely 70% 失败

    If the fixture is required for test setup, tests may fail due to missing dependencies.
