Question

我有什么：

我有一个TestBase.py我正在使用它作为抽象测试类。

from abc import abstractmethod

class TestBase:

    expectData = None

    def test_check_expectData(self):
        if self.expectData is None:
            raise NotImplementedError('you must have expectData')

    @abstractmethod
    def test_command_OK(self):
        raise NotImplementedError('subclasses must override test_command()!')

我希望其他人继承TestBase。例如TestDemo.py

import unittest
from TestBase import TestBase

class TestDemo(unittest.TestCase, TestBase):

    expectData = ["someData"]

    def test_command_OK(self):
        self.assertTrue(True)

if __name__ =='__main__':
    unittest.main()

如果我运行python TestDemo.py，一切都按预期工作。如果我没有预期日期，我将获得NotImplementedError，如果我没有test_command_OK方法，我会获得NotImplementedError: subclasses must override test_command()!

问题：

当我从setup.py python setup.py test运行测试套件时，事情就中断了。我认为setup.py自己和TestBase类TestBase中运行expectedData类的原因是None，因此无法通过测试。

====================================================================== ERROR: myProject.tests.TestDemo.TestBase.test_check_expectData
---------------------------------------------------------------------- Traceback (most recent call last):   File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)   File "/Users/z002x6m/Desktop/myProject/tests/TestBase.py", line 49, in test_check_expectData
    if self.expectData is None: AttributeError: TestBase instance has no attribute 'expectData'
====================================================================== ERROR: myProject.tests.TestDemo.TestBase.test_command_OK
---------------------------------------------------------------------- Traceback (most recent call last):   File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)   File "/Users/z002x6m/Desktop/myProject/tests/TestBase.py", line 57, in test_command_OK
    raise NotImplementedError('subclasses must override test_command()!') NotImplementedError: subclasses must override test_command()!

如果我在print(self.__class__)方法中打印出test_check_expectData(self)，当我直接运行TestDemo时，我得到<class '__main__.TestDemo'>，这时候一切正常。当我运行myProject.tests.TestDemo.TestBase时，我得到python setup.py test。

有没有办法告诉setup.py不要运行TestBase课程？也许@unittest.skipis , @unittest.skipif, @unittest.skipunless？但我不希望子类跳过这些需要测试，因为我希望所有子类都有expectData。 TestBase用作模板，force / check子测试类具有expectData等所有要求。但它不应该自己运行。我该怎么办才能通过这个问题？即使意味着要重新构建我当前的测试框架，我也不介意建议

显然，如果子类super() TestBase类

，则使用SkipTest会跳过测试

from unittest.case import SkipTest

    def test_check_expectData(self):
        if self.expectData is None:
            raise SkipTest

python unittest阻止抽象testBase类测试本身
