如何进行单元测试单元测试测试用例

发布于 2024-12-18 16:04:23 字数 853 浏览 4 评论 0原文

我有一个 unittest.TestCase 子项,它定义了几个特定于域的断言检查。 我想运行一些单元测试来对该功能进行单元测试,以控制未来更新中的一切工作。

class MyBaseTestCase(unittest.TestCase):
    def setUp(self):
        ...
    def tearDown(self):
        ...
    def run(self, result):
        ...
    def assertSpec(self, condition, message):
        ...

我想在其他单元测试中实例化 MyBaseTestCase,如下所示:

class TestBase(unittest.TestCase):
    def test_assertSpec(self):
        self.testclass = MyBaseTestCase()
        self.assertRaises(AssertionError, self.testclass.assertSpec, False)

我遇到了多个不同的错误,所以我的问题是对自定义单元测试函数进行单元测试的常见做法是什么?

在执行此操作时, 帮助:

$ jython
>>> import sys
>>> sys.version
'2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06) \n[Java HotSpot(TM) Server VM (Sun Microsystems Inc.)]'

I have a unittest.TestCase child, which defines several domain specific assert Checks.
I would like to run some unittests to unittest this functionality to control that everything work on future updates.

class MyBaseTestCase(unittest.TestCase):
    def setUp(self):
        ...
    def tearDown(self):
        ...
    def run(self, result):
        ...
    def assertSpec(self, condition, message):
        ...

I want to instantiate MyBaseTestCase in other unit test, like this:

class TestBase(unittest.TestCase):
    def test_assertSpec(self):
        self.testclass = MyBaseTestCase()
        self.assertRaises(AssertionError, self.testclass.assertSpec, False)

I'm encountering multiple different errors, when doing this, so my question is what is a common practice for unittesting custom unittest functions?

In case it helps:

$ jython
>>> import sys
>>> sys.version
'2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06) \n[Java HotSpot(TM) Server VM (Sun Microsystems Inc.)]'

不确定是否有任何 Jython 特定的东西会破坏这个,但我会做这样的事情:

import StringIO
import unittest


# The TestCase subclass to test    
class MyBaseTestCase(unittest.TestCase):
    def assertSpec(self, thing):
        assert thing == 123


# The testcase for MyBaseTestCase
class TestMyTest(unittest.TestCase):
    def test_assetSpec(self):
        """Ensure assertSpec works
        """

        class _TestSpec(MyBaseTestCase):
            def test_failure_case(self):
                 self.assertSpec(121)
            def test_success_case(self):
                 self.assertSpec(123)

        # Load tests from _TestSpec
        loader = unittest.TestLoader()
        suite = loader.loadTestsFromTestCase(_TestSpec)

        # Create runner, and run _TestSpec
        io = StringIO.StringIO()
        runner = unittest.TextTestRunner(stream = io)
        results = runner.run(suite)

        # Should be one failed test, and one passed test
        self.assertEquals(results.testsRun, 2)
        self.assertEquals(len(results.failures), 1)

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

Not sure if there's anything Jython specific that would break this, but I would do something like this:

import StringIO
import unittest


# The TestCase subclass to test    
class MyBaseTestCase(unittest.TestCase):
    def assertSpec(self, thing):
        assert thing == 123


# The testcase for MyBaseTestCase
class TestMyTest(unittest.TestCase):
    def test_assetSpec(self):
        """Ensure assertSpec works
        """

        class _TestSpec(MyBaseTestCase):
            def test_failure_case(self):
                 self.assertSpec(121)
            def test_success_case(self):
                 self.assertSpec(123)

        # Load tests from _TestSpec
        loader = unittest.TestLoader()
        suite = loader.loadTestsFromTestCase(_TestSpec)

        # Create runner, and run _TestSpec
        io = StringIO.StringIO()
        runner = unittest.TextTestRunner(stream = io)
        results = runner.run(suite)

        # Should be one failed test, and one passed test
        self.assertEquals(results.testsRun, 2)
        self.assertEquals(len(results.failures), 1)

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