具有多个命令行选项的pytest

Question

我对pytest的一个命令行参数没有问题。

运行程序时：
python-m pytest-q-v--confcutdir=/usr/local/penguin/home/px09/p001--cmdopt=type1 test suite.py

我得到了预期的回应：

================================================ FAILURES ================================================
______________________________________________ test_answer _______________________________________________

cmdopt = 'type1'

    def test_answer(cmdopt):
        if cmdopt == "type1":
            print ("first")
        elif cmdopt == "type2":
            print ("second")
>       assert 0 # to see what was printed
E       assert 0

test-suite.py:7: AssertionError
------------------------------------------ Captured stdout call ------------------------------------------
first
======================================== 1 failed in 0.01 seconds ==============

当我尝试多个参数时，我会遇到问题

def test_answer(cmdopt):
    if cmdopt == "type1":
        print ("first")
    elif cmdopt == "type2":
        print ("second")
    assert 0 # to see what was printed

def test_answer2(cmdopt2):
    if cmdopt2 == "type1":
        print ("first")
    elif cmdopt2 == "type2":
        print ("second")
    assert 0 # to see what was printed

import pytest

def pytest_addoption(parser):
    parser.addoption("--cmdopt", action="store", default="type1",
        help="my option: type1 or type2")
    parser.addoption("--cmdopt2", action="store", default="type3",
                     help="my option: type3 or type4")

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

def cmdopt2(request):
    return request.config.getoption("--cmdopt2")

我认为问题很简单。只需在cmdopt2函数之前添加@pytest.fixture decorator

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

@pytest.fixture
def cmdopt2(request):
    return request.config.getoption("--cmdopt2")
