怎么用pytest --fixtures [testpath] 来查看当前可用的 fixtures
时间: 2024-02-19 09:03:12 浏览: 18
你可以在终端中进入到你的代码目录,然后输入以下命令:
```
pytest --fixtures [testpath]
```
其中 `[testpath]` 是你要测试的文件或目录的路径。这个命令会列出所有可用的 fixtures 以及它们的用法和参数。你可以根据这个列表来查看是否缺少了你需要的 fixture 或者是否使用了错误的参数。

用pytest --fixtures [testpath] 显示no docstring available
The "no docstring available" message that you are seeing when running "pytest --fixtures [testpath]" indicates that there is no docstring (i.e., documentation string) available for the fixture that you are trying to display.
A docstring is a string literal that appears as the first statement in a module, function, class, or method definition. It is used to provide documentation for the code and is accessible via the "__doc__" attribute of the object.
To add a docstring to a fixture, you can simply add a string as the first line of the fixture function definition. For example:
```
import pytest
@pytest.fixture
def my_fixture():
"""
This is the docstring for my_fixture.
"""
return 42
```
When you run "pytest --fixtures [testpath]" again, you should see the docstring displayed for the "my_fixture" fixture.
use 'pytest --fixtures [testpath]' for help on them.
A:pytest --fixtures [testpath] 用于列出测试路径中可用的所有 fixtures 的帮助信息。Fixtures 是 pytest 的一个强大功能,它允许您在测试方法之间共享测试数据和资源,并封装测试方法的设置和清理。 在 pytest 中,fixtures 通常定义在 conftest.py 文件中,每个 fixture 都是一个带有装饰器的函数,当测试方法请求该 fixture 时,pytest 将在 conftest.py 中查找该函数并返回装饰器函数的返回值作为 fixture 的值。
