Pytest测试需要在收集阶段和设置时进行参数化

Question

我有一些测试，我想使用一些参数进行参数化，这些参数需要在收集阶段进行参数化，而有些参数需要在设置时进行参数化。我无法使用metafunc。在pytest_generate_test钩子中参数化，因为我需要一些fixture具有indirect=True以将argname作为请求传递。参数，但其他参数需要有间接=False。

有什么办法吗?

下面是我的测试和我想要做的一个例子:

def pytest_generate_tests(metafunc):
    if metafunc.function.__name__ == 'test_example':
        argnames = []
        argvalues = []
        parameters = getattr(metafunc.function, 'paramlist', ())
        for p in parameters:
            if type(p) == list:
                argnames = tuple(['myfixture'] + p)
            else:
                argvalues.append = tuple(['std'] + p['argvalues'])
            argvalues.append = tuple(['pro'] + p['argvalues'])
        # I want to do the following, but it won't work since some of the
        # args need indirect set to true and some need indirect set to false.
        metafunc.parametrize(argnames, argvalues, indirect=True)
    elif 'myfixture' in metafunc.fixturenames:
        # we have existing tests which use the fixture, but only with
standard
        metafunc.parametrize("myfixture", "std")
    else:
        # we have existing tests which use older style parametrization,
non-fixture
        for p in getattr(metafunc.function, 'paramlist', ()):
            metafunc.addcall(funcargs=p)

def params(decolist):
    def wrapper(function):
        function.paramlist = decolist
        return function
    return wrapper
@pytest.fixture
def myfixture(request):
    If request.param == 'std':
        myfix = SomeObject()
    elif request.param == 'pro':
        myfix = SomeOtherObject()
    def fin():
        myfix.close()
    request.addfinalizer(fin)
    return myfix
@params([
    ['color', 'type'],
    { 'argvalues': [ 'blue', 'cat'] },
    { 'argvalues': ['pink', 'dog'] }
])
def test_example(myfixture, color, type):
    # this is the new test we want to add
def test_something(myfixture):
    # existing test which only uses std fixture
@params([
    {'arg1': 1, 'arg2': 2},
    {'arg1': 3, 'arg2': 5}
])
def test_old_style(arg1, arg2):
    # existing tests which don't use fixtures

感谢您的阅读!我知道它很长

每个设计都在收集时进行参数化
