我有一些测试,我想使用一些参数来进行参数化,这些参数需要在收集阶段发生参数化,还有一些需要在设置时发生。我无法在pytest_generate_test钩子中使用 metafunc.parametrize,因为我需要一些fixtures以indirect = True将argname作为request.param传递,但其他参数需要具有indirect = False。pytest测试需要在收集阶段和设置时间进行参数化

任何想法如何做到这一点?

这是我想要做什么的我的测试是什么样子的例子和:

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 

感谢您在此阅读!我知道这很长。

每个设计所有参数化发生在收集时间
