Passing command line arguments to an already parameterized pytest test
问题
我已经对pytest测试进行了参数化。如何向测试添加一个额外的参数，该参数作为命令行参数传递给pytest？
我尝试向解析器添加一个名为xyz的选项，并将命令行参数作为一个fixture返回，就像这样。。
conftest.py:
def pytest_addoption(parser):parser.addoption("--some_other_option", action="store_true", default=True, help="Skip some tests")parser.addoption("--xyz", action="store_true", default=True, help="Test xyz")@pytest.fixturedef xyz(config):return config.getoption('--xyz')
测试文件:
@pytest.mark.parametrize('arg1, arg2, arg3, arg4, arg5', [('asdf', 1, 1, 0, [0.64]),...])def test_stuff(arg1, arg2, arg3, arg4, arg5, xyz):if xyz: # 仅在xyz为True时执行此操作assert func(arg3) == 42....
我也尝试过这样做。在两种情况下，问题是pytest对每个测试都返回错误
`E fixture 'config' not found
我做错了什么？`

I have parameterized pytest tests. How to add an additional parameter to the tests that is passed to pytest as a command line argument?
I tried adding an option xyz to the parser and put return the command line argument as a fixture, like so..
conftest.py:
def pytest_addoption(parser):parser.addoption("--some_other_option", action="store_true", default=True, help="Skip some tests")parser.addoption("--xyz", action="store_true", default=True, help="Test xyz")@pytest.fixturedef xyz(config):return config.getoption('--xyz')
test file:
@pytest.mark.parametrize('arg1, arg2, arg3, arg4, arg5', [(asdf', 1, 1, 0, [0.64]),...])def test_stuff(arg1, arg2, arg3, arg4, arg5, xyz):if xyz: # only do this if xyz is Trueassert func(arg3) == 42....
I have also tried it like this.
In both cases, the issue is that pytest returns an error for every test
`E fixture 'config' not found
What am I doing wrong?

“config”对象可以从“pytest_configure”钩子 (https://docs.pytest.org/en/7.1.x/reference/reference.html#pytest.hookspec.pytest_configure) 中访问。但是通过“request”也足够了。
所以，如果您想要“xyz”作为一个fixture，您可以尝试：
@pytest.fixturedef xyz(request):return request.config.getoption('--xyz')
英文:
The config object is accessible from the pytest_configure hook (https://docs.pytest.org/en/7.1.x/reference/reference.html#pytest.hookspec.pytest_configure). But with request it is enough.
So if you want xyz as a fixture, you could try:
@pytest.fixturedef xyz(request):return request.config.getoption('--xyz')
