如何通过命令行在pytest中传递参数 [英] How to pass arguments in pytest by command line

问题描述

我有一个代码，我需要从终端传递诸如name之类的参数.这是我的代码以及如何传递参数.我收到了我不理解的找不到文件"类错误.

I have a code and I need to pass the arguments like name from terminal. Here is my code and how to pass the arguments. I am getting a "File not found" kind error that I don't understand.

我已经在终端中尝试了以下命令: pytest< filename> .py-杏仁我应该将名称打印为杏仁"

I have tried the command in the terminal: pytest <filename>.py -almonds I should get the name printed as "almonds"

@pytest.mark.parametrize("name")
def print_name(name):
    print ("Displaying name: %s" % name)

推荐答案

在pytest测试中，请勿使用 @ pytest.mark.parametrize :

In your pytest test, don't use @pytest.mark.parametrize:

def test_print_name(name):
    print ("Displaying name: %s" % name)

在 conftest.py 中:

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


def pytest_generate_tests(metafunc):
    # This is called for every test. Only get/set command line arguments
    # if the argument is specified in the list of test "fixturenames".
    option_value = metafunc.config.option.name
    if 'name' in metafunc.fixturenames and option_value is not None:
        metafunc.parametrize("name", [option_value])

然后，您可以使用命令行参数从命令行运行:

Then you can run from the command line with a command line argument:

pytest -s tests/my_test_module.py --name abc
