使用nose和python时TestCase类中的对象范围

Question

我用鼻子。你知道吗

我现在的代码是：

class A():
    def __init__():
        pass
    def do_somthing(self):
        do_it

class Test(unittest.TestCase):
    def setUp(self):
        self.a = A()
    def testSomthing:
        raise assert(self.a.do_something())

我不想每次测试都创建一个类的实例，我只想创建一次。我该怎么做？你知道吗

您可以使用setUpClass，请参见the documentation：

A class method called before tests in an individual class run. setUpClass is called with the class as the only argument and must be decorated as a classmethod():

@classmethod
def setUpClass(cls):
    ...
