python unittest计数测试

经过多次试验和错误，我终于可以正常工作了。

基于scoffey的答案。

希望能帮助到你。

import unittest

class MyTest(unittest.TestCase):

    currentResult = None # holds last result object passed to run method

    @classmethod
    def setResult(cls, amount, errors, failures, skipped):
        cls.amount, cls.errors, cls.failures, cls.skipped = \
            amount, errors, failures, skipped

    def tearDown(self):
        amount = self.currentResult.testsRun
        errors = self.currentResult.errors
        failures = self.currentResult.failures
        skipped = self.currentResult.skipped
        self.setResult(amount, errors, failures, skipped)

    @classmethod
    def tearDownClass(cls):
        print("\ntests run: " + str(cls.amount))
        print("errors: " + str(len(cls.errors)))
        print("failures: " + str(len(cls.failures)))
        print("success: " + str(cls.amount - len(cls.errors) - len(cls.failures)))
        print("skipped: " + str(len(cls.skipped)))

    def run(self, result=None):
        self.currentResult = result # remember result for use in tearDown
        unittest.TestCase.run(self, result) # call superclass run method

    def testA(self):
        self.assertTrue(True) # succeeds

    def testB(self):
        self.assertTrue(False) # fails

    def testC(self):
        self.assertTrue(1 + None is None) # raises TypeError

    @unittest.skip("skip it") # skipped
    def testD(self):
        self.assertTrue("whatever")

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

运行脚本

python test.py > result.txt

result.txt：

tests run: 3
errors: 1
failures: 1
success: 1
skipped: 1

我不确定这是否是最好的方法，但它是否有效。Unittest模块易于使用，但很难掌握，现在我对此几乎一无所知。
