找不到参数的夹具

Question

我正在尝试运行我的 pytest 参数化测试。

def testConfiguration(numberOfSmall, numberOfMedium, numberOfLarge,numaValue):
   ...

@pytest.mark.parametrize("small, medium, large, numaValue, out", [
(0,0,1,0,True),
(0,0,1,1,True),
(0,0,2,0,True),
(1,1,1,0,True),
(0,1,1,0,True),
(1,0,1,0,True),
(0,1,0,0,True),
(0,1,0,1,True),
(0,2,0,0,True),
(2,2,0,0,True),
(2,1,0,0,True),
(1,0,0,0,True),
(1,0,0,1,True),
(2,0,0,0,True),
(2,0,0,1,True),
(3,0,0,0,True),
(3,0,0,1,True),
(4,0,0,0,True),
(4,1,0,0,True),
(5,0,0,0,True),
(6,0,0,0,True),
])
def testAll(small, medium, large, numaValue, out):
    assert testConfiguration(small, medium, large, numaValue) == out

然而，当我这样做时，我在 pytest 中遇到了这个错误。

E       fixture 'numberOfSmall' not found
>       available fixtures: cache, capfd, capfdbinary, caplog, capsys, capsysbinary, doctest_namespace, monkeypatch, pytestconfig, record_property, record_xml_attribute, record_xml_property, recwarn, tmp_path, tmp_path_factory, tmpdir, tmpdir_factory
>       use 'pytest --fixtures [testpath]' for help on them.

请注意，错误是 非致命性的，程序的其余部分会正常执行。

为什么将 numberOfSmall 视为固定装置？相同的名称未用作函数名称。

Answer 1

由于您为其指定的名称，testConfiguration 似乎被视为测试。如果您传递给测试的所有参数不是来自测试示例中的参数化，则它们将被视为固定装置。要解决它，只需将您的函数重命名为 getTesttestConfiguration() 左右。作为旁注，在 python 中通常使用蜗牛式表示法，而不是您选择的驼峰式表示法。
