Question

我试图跳过依赖于命令行参数值的特定测试。我尝试使用pytest.config.getoption("--some-custom-argument")获取参数值，如测试文件中此related question suggestion中所述，并通过skipif检查参数值。但pyest没有config。通过request.config.getoption("--some-custom-argument")获取参数值似乎只适用于夹具函数。我可以在测试执行之前获得命令行参数，但是我可以在skipif的文件范围级别检查它们吗？

由于在配置阶段之后和测试集合之前（即在测试执行之前）收集测试，因此pytest.config在测试模块的模块级别可用。例如：

# conftest.py
def pytest_addoption(parser):
    parser.addoption('--spam', action='store')

# test_spam.py
import pytest


print(pytest.config.getoption('--spam'))


@pytest.mark.skipif(pytest.config.getoption('--spam') == 'eggs', 
                    reason='spam == eggs')
def test_spam():
    assert True

以--spam=eggs运行产生：

$ pytest -vs -rs --spam=eggs

You can try to do like that

@pytest.mark.skipif(pytest.config.option.some-custom-argument=='foo', 
                    reason='i do not want to run this test')

But why not to use mark expressions?

如果我理解正确的问题，那么您可能想看看这个answer。

建议使用带有request对象的灯具，并从request.config.getoption("--option_name")或request.config.option.name那里读取输入参数值。

代码段（版权归ipetrik所有）：

# test.py
def test_name(name):
    assert name == 'almond'


# conftest.py
def pytest_addoption(parser):
    parser.addoption("--name", action="store")

@pytest.fixture(scope='session')
def name(request):
    name_value = request.config.option.name
    if name_value is None:
        pytest.skip()
    return name_value

在测试执行之前无法获得pytest命令行参数？
