如何使用命令行在pytest中传递多个参数?

[英]How to pass multiple arguments in pytest using command line?

我想将输入作为命令行选项传递给我的pytest文件。 这个问题https://stackoverflow.com/a/42145604/8031479是有帮助的,但我不知道添加多个解析器采用。

我已经尝试将此添加到我的conftest.py文件中,但没有帮助:

def pytest_addoption(parser):
    """
        This function is used to extract input1 and input2 values from the command line
    """
    parser.addoption(
        "--input1", action="store", default="input1"
    )
    parser.addoption(
        "--input2", action="store", default="input2"
    )

我的test.py文件的内容:

import pytest

@pytest.fixture()
def get_input1(input1):
    print 'input1:', input1
    return input1

# @pytest.mark.unit
@pytest.fixture()
def get_input2(input2):
    print 'input2:', input2
    return input2

def test_hello(get_input1, get_input2):
    print 'testing pytest fixtures with command line options'
    print get_input1, get_input2

这是我运行test.py文件的命令:

py.test test.py --input1="hello" --input2="world"

我收到此错误消息:

@pytest.fixture()
def get_input1(input1):
E       fixture 'input1' not found
>       available fixtures: cache, capfd, capfdbinary, caplog, capsys, capsysbinary, doctest_namespace, get_input1, get_input2, metadata, monkeypatch, pytestconfig, record_property, record_xml_attribute, recwarn, tmp_path, tmp_path_factory, tmpdir, tmpdir_factory
>       use 'pytest --fixtures [testpath]' for help on them.

你可以这样工作:

conftest.py:

import pytest


def pytest_addoption(parser):
    parser.addoption("--input1", action="store", default="default input1")
    parser.addoption("--input2", action="store", default="default input2")



@pytest.fixture
def input1(request):
    return request.config.getoption("--input1")


@pytest.fixture
def input2(request):
    return request.config.getoption("--input2")

test.py:

import pytest

@pytest.mark.unit
def test_print_name(input1, input2):
    print ("Displaying input1: %s" % input1)
    print("Displaying input2: %s" % input2)

CLI:

>py.test -s test.py --input1 tt --input2 12
