python自动化测试_从命令行运行测试用例with verbosity

class RomanNumeralConverter(object):    def __init__(self, roman_numeral):        self.roman_numeral = roman_numeral        self.digit_map = {"M":1000, "D":500, "C":100, "L":50, "X":10,                           "V":5, "I":1}    def convert_to_decimal(self):        val = 0        for char in self.roman_numeral:            val += self.digit_map[char]        return val    import unittestclass RomanNumeralConverterTest(unittest.TestCase):            def test_parsing_millenia(self):        value = RomanNumeralConverter("M")        self.assertEquals(1000, value.convert_to_decimal())            def test_parsing_century(self):        '''THIS is a error test case'''        value = RomanNumeralConverter("C")        self.assertEquals(10, value.convert_to_decimal())                        if __name__ == "__main__":    suite = unittest.TestLoader().loadTestsFromTestCase(RomanNumeralConverterTest)    unittest.TextTestRunner(verbosity=2).run(suite)

运行结果：

测试用例失败时就是这个样子
