pytest-deadfixtures 2.1.0

重要

–dead fixtures选项不会运行您的测试，而且对于pytest收集步骤中的错误也是合理的。 如果使用作为ci进程的一部分，建议在默认测试运行之后运行它。例如：

script:
  - pytest
  - pytest --dead-fixtures

列出未使用的装置

只需运行“pytest”和一个额外的选项“dead fixtures”：

$ pytest --dead-fixtures
============================= test session starts ==============================
(hidden for brevity)

Hey there, I believe the following fixture(s) are not being used:
Fixture name: some_fixture, location: test_write_docs_when_verbose.py:5

========================= no tests ran in 0.00 seconds =========================

使用一定的详细程度也会打印每个设备的docstring:

$ pytest --dead-fixtures -v
============================= test session starts ==============================
(hidden for brevity)

Hey there, I believe the following fixture(s) are not being used:
Fixture name: some_fixture, location: test_write_docs_when_verbose.py:5
    Blabla fixture docs

========================= no tests ran in 0.00 seconds =========================

列出重复的fixture

既然您删除了测试套件中所有未使用的fixture，那么如果您想多跑一英里呢？

一个重要的注意事项是，它使用fixture返回值来验证两个或多个fixture是否相等。

这意味着没有truthy返回值的fixtures将被跳过。

您应该仅将其用作提示，在删除其中一个设备之前，请确认两个设备提供的功能确实重复。

只需使用额外的选项“-dup fixtures”运行“pytest”，与“dead fixtures”选项不同，它通常会运行您的测试：

$ pytest --dup-fixtures
======================================================================================================================== test session starts ========================================================================================================================
(hidden for brevity)

tests/test_deadfixtures.py ........

You may have some duplicate fixtures:
Fixture name: someclass_fixture, location: test_repeated_fixtures.py:12
Fixture name: someclass_samefixture, location: test_repeated_fixtures.py:17
