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，有些需要在设置时进行。我无法在 pytest_generate_test 钩子中使用 metafunc.parametrize，因为我需要一些固定装置具有间接 = True 以将 argname 作为 request.param 传递，但其他参数需要具有间接 = False。
任何想法如何做到这一点？
这是我的测试的样子和我想做的一个例子：
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
