pytest说我没有找到夹具时找不到夹具

Question

我正在尝试对测试场景进行参数化,因此我不必为xUnit样式测试中的每个场景制作单独的案例.

这是pytest的一个例子,我正在尝试复制我自己的用例.

    from datetime import datetime, timedelta

testdata = [
    (datetime(2001, 12, 12), datetime(2001, 12, 11), timedelta(1)),
    (datetime(2001, 12, 11), datetime(2001, 12, 12), timedelta(-1)),
]


@pytest.mark.parametrize("a,b,expected", testdata)
def test_timedistance_v0(a, b, expected):
    diff = a - b
    assert diff == expected

上面的工作很好,但是当我尝试修改它以供我使用时,如下所示.我收到一条错误,说"找不到"转储夹具.我不知道发生了什么.这是我第一次使用pytest,所以也许我没有得到什么.

dump1 = load_dump(pathtodump1,pathtodump2) # load_dump can take multiple params
dump2 = load_dump(pathtodump3)

scenarios = [(dump1,{'prod_str':None}),
             (dump2,{'prod_str':"123"})]

@pytest.mark.paramaterize("dump,expected_meta", scenarios)
def test_metadump_profiles(dump, expected_meta):
        meta = dump.meta
        assert meta.prod_str == expected_meta['prod_str']

这是我从pytest得到的错误.我还应该提一下,当我调试时,测试永远不会运行,它会在paramaterize装饰器中的某处失败.

@pytest.mark.paramaterize

这是无效的,而pytest会抛出一个没有意义的模糊错误.这是由拼写错误引起的......

@pytest.mark.parametrize

是有效的拼写.愚蠢的虫子我把头发拉了出来.有关详细信息,请参阅有关此主题的github问题.
