在conftest.py中使用pytest_configure（）时pytest --help无法运行

Question

随着我发现更多内容，更新问题和主题。 没有conftest.py，“ pytest --help”将返回帮助内容。 与conftest.py“ pytest --help”返回此

我的conftest.py

def pytest_addoption(parser):
    parser.addoption("--user", action="store", default="admin", help="user name")
    parser.addoption("--password", action="store", default="password", help="user password")

@pytest.fixture(scope='module')
def pytest_configure(config):
      import env
      if config.getoption('--user'):
          env.user_name = config.getoption('--user')

conftest.py已经两个月没有更新了，但是我有一台新笔记本电脑。 Mac High Sierra。

Python 3.6.6 . or 3.7.0
pytest version 3.7.1, or 3.7.0

钩子不是固定装置，它们是pytest使用其精确签名可以找到的简单函数。 因此，要解决您的问题，只需从钩子中删除pytest.fixture装饰器，就可以了：

def pytest_configure(config):
    import env
    if config.getoption('--user'):
        env.user_name = config.getoption('--user')
