在鼻子parameterize.expand调用中使用类方法 [英] use class method in nose parameterize.expand call

问题描述

我有一个生成器方法正在构建大量的测试标准，我知道我可以使非类方法被调用，但是我宁愿将参数构建方法作为我的测试类的一部分.有办法吗?

I have a generator method that is building a large set of test criteria, I know i can make a non class method to be called, but I much rather have the parameter building method be part of my test class. is there a way to do this?

这是我要做什么的简单描述:

here is a simple description of what I want to do:

class MyUnitTestClass(TestCase):
  @staticmethod
  def generate_scenarios():
    yield ('this_is_my_test', 1, 2)

  @parameterized.expand(generate_scenarios())
  def test_scenario(self, test_name, input, expected_output)
    self.assertEquals(input+input, expected_output) 

现在我要执行以下操作:

right now I have do do the following:

def generate_scenarios():
    yield ('this_is_my_test', 1, 2)    

class MyUnitTestClass(TestCase):

  @parameterized.expand(generate_scenarios())
  def test_scenario(self, test_name, input, expected_output)
    self.assertEquals(input+input, expected_output) 

TL; DR::我希望我的方案generate_scenarios方法在调用它的测试类中.

TL;DR: I want my scenario generate_scenarios method to be within the test class that is calling it.

推荐答案

只需删除@staticmethod，它就可以工作. generate_scenarios仅仅是在类中定义的一个函数，您将获得适合您的参数化扩展功能:

Just remove @staticmethod and it should work. generate_scenarios would be just a function defined within class and you will get parametirised expansion working for you:

from unittest import TestCase

from nose_parameterized import parameterized

class MyUnitTestClass(TestCase):
  def generate_scenarios():
    yield ('this_is_my_test', 1, 2)

  @parameterized.expand(generate_scenarios())
  def test_scenario(self, test_name, input, expected_output):
    self.assertEquals(input+input, expected_output)

这是我的运行方式:

$ nosetests stackoverflow.py -v
test_scenario_0_this_is_my_test (stackoverflow.MyUnitTestClass) ... ok

----------------------------------------------------------------------
Ran 1 test in 0.002s

OK

您可能还需要查看 Python装饰器作为静态方法
