pytest 命令行参数化

pytest支持通过命令行传递参数来进行参数化。首先需要在conftest.py中添加命令行选项，可以使用pytest_addoption函数来实现。在该函数中，可以通过parser.addoption方法添加参数选项，比如"--cmdopt"。然后，可以在用例中使用fixture来调用cmdopt函数，从命令行传入的参数可以通过该函数获取到。例如：@pytest.fixture(scope='class') def cmdopt(request): return request.config.getoption("--cmdopt")。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
