失败后，Python单元测试将继续

本文介绍了失败后，Python单元测试将继续的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在 unittest 中失败后继续测试的最佳方法是什么?

What's the best way of continuing tests after failure in unittest?

#!/usr/env/bin python2.7 import unittest from fib import fib class FibTests(unittest.TestCase): def test_0(self): self.assertEqual(fib(0), 0) self.assertEqual(fib(1), 1) self.assertEqual(fib(2), 1) self.assertEqual(fib(5), 5) self.assertEqual(fib(10), 55) def test_1(self): self.assertEqual(fib(0), 1) def test_2(self): self.assertEqual(fib(1), 0) self.assertEqual(fib(5), 0) if __name__ == '__main__': suite = unittest.TestLoader().loadTestsFromTestCase(FibTests) result = unittest.TextTestRunner(verbosity=2).run(suite)

看一下test_2，它只会告诉我失败是1次，而不是2次.

Looking at test_2, it'll only tell me there's 1 failure instead of 2.

此外，我如何在结尾处说明结果:

Additionally, how can I collect the results at the end stating:

test_0 -- 0 failures test_1 -- 1 failures test_2 -- 2 failures

动机:

我正在尝试创建一个测试游戏.人们提交测试，如果他们失败了别人的程序，他们会得到分数；每次测试失败都是一分.提供这种功能的最简单方法是什么?

I'm trying to create a testing game. People submit tests and if they fail others' programs they get points; each test failure is one point. What's the easiest way of providing this type of capability?

推荐答案

您必须将每个测试用例分为不同的方法.为了更轻松地创建新测试/节省键入时间，您可以根据这样的输入自动生成测试用例

You have to separate each test case into different method. To make it easier to create new test / save typing time, you can auto-generate test case based on input like this

#!/usr/env/bin python2.7 import unittest from fib import fib class FibTests(unittest.TestCase): pass def test_gen(expected, actual): def test_method(self): return self.assertEqual(expected, actual) return test_method if __name__ == '__main__': cases = ((fib(1), 1), (fib(2), 1), (fib(5), 5)) for index, case in enumerate(cases): test_name = 'test_{0}'.format(index) test = test_gen(case[1], case[0]) setattr(FibTests, test_name, test) suite = unittest.TestLoader().loadTestsFromTestCase(FibTests) result = unittest.TextTestRunner(verbosity=2).run(suite)
