单元测试未运行 [英] Unit Test not running

问题描述

我被一些单元测试卡住了.

I'm getting stuck with some unittests.

这是我能想到的最简单的例子:

Here's the simplest example I could come up with:

#testito.py
import unittest

class Prueba(unittest.TestCase):

    def setUp(self):
        pass
    def printsTrue(self):
        self.assertTrue(True)

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

问题是，运行这个没有效果:

Problem is, running this has no effect:

$ python testito.py 

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

我正在挠头，因为我没有发现上面的代码有任何问题.现在发生了几次测试，我真的不知道下一步该怎么做.有什么想法吗?

I'm scratching my head as I don't see any problem with the code above. It happened with a couple of tests now and I don't really know what to do next. Any idea?

推荐答案

默认情况下，只运行名称以 test 开头的函数:

By default, only functions whose name that start with test are run:

class Prueba(unittest.TestCase):

    def setUp(self):
        pass
    def testPrintsTrue(self):
        self.assertTrue(True)

来自unittest基本示例:

测试用例是通过子类化 unittest.TestCase 创建的.这三个单独的测试是用名称以字母 test 开头的方法定义的.此命名约定告知测试运行器哪些方法代表测试.

A testcase is created by subclassing unittest.TestCase. The three individual tests are defined with methods whose names start with the letters test. This naming convention informs the test runner about which methods represent tests.
