pytest：如何定义强制性命令行参数

Question

How can I define custom command line arguments, and make them mandatory in pytest? For example, I want something like this: pytest -s sample.py --test_suite='some_value' And the command line argument "--test_suite" has to be mandatory. If its missing, I want to throw a "help" like message which says "enter the test_suite to be executed"

This is my code:

@pytest.fixture
def testsuite(request):
test_suite = request.config.getoption('--test_suite')
return test_suite

def pytest_addoption(parser):
parser.addoption("--test_suite",action="store",default="default_suite",
                 help="Enter the test suite you want to execute."
                      "Ex. --test_suite=default_suite"
                      "If nothing is selected, default_suite tests will be run.")   

This approach makes the command line arguments optional. But I want to make them mandatory.

要使用addoption将命令行参数标记为强制参数，请将required=True添加为方法调用的关键字参数
