I am trying to execute doSomething() before every test I have. I just want to execute doSomething() one time. However, I am getting the next error message: "setUpClass error: NameError: global name 'doSomething' is not defined"

I have seen several examples of the implementation of setUpClass here in stackoverflow and my code is exactly as in those examples. I have been trying to change a lot of things in my code to make it works with no luck and I feel I am a little bit lost here.

Can anybody help me? Am I missing something?

Here is my code:

class Test_A(unittest.TestCase):

   def doSomething(self):

        print("class A")



   @classmethod

   def setUpClass(cls):

        doSomething()



   def test_1(self):

        print("test 1")



   def test_2(self):

        print("test 2")

I am using python 2.7

Follow the advice from Martijn:

class Test_A(unittest.TestCase):

   @classmethod

   def doSomething(self):

        print("class A")



   @classmethod

   def setUpClass(cls):

        cls.doSomething()



Test_A.setUpClass()

Output:

class A

cls is the implicit first argument of the call. Just as self is our convention for the object invoking an instance method, cls is used for the class calling the class method.

This is convention, not a language requirement. You're free to use any valid identifier: self for everything, or caller, or even xyzzy or plugh. The convention merely makes it easier for others to recognize the calling object.
