我有一个功能,如果测试功能成功,应该报告。

但是,如果测试函数内部有异常,我不想报告。

我尝试使用 pytest.fixture、pytest.yield_fixture,但它们都总是调用终结器。我怎么能理解,在测试功能中引发了异常?

test.py StatisticClass: start
FStatisticClass: stop
finalizer

test.py 竞赛:

@pytest.mark.usefixtures("statistic_maker")
def test_dummy():
    raise Exception()

conftest.py 的内容:

class StatisticClass():

    def __init__(self, req):
        self.req = req
        pass

    def start(self):
        print "StatisticClass: start"

    def stop(self):
        print "StatisticClass: stop"

    def if_not_exception(self):
        """
        I don't want to call this if Exception inside yield.
        Maybe, there is any info in request object?
        """
        print "finalizer" 


@pytest.yield_fixture(scope="function")
def statistic_maker(request):
    ds = StatisticClass(request)
    ds.start()
    request.addfinalizer(ds.if_not_exception) 
    yield
    ds.stop()

PS 我不能使用装饰器,因为我使用的是夹具。
