本文实例讲述了python自动化测试之从命令行运行测试用例with verbosity，分享给大家供大家参考。具体如下：

实例文件recipe3.py如下：

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 unittest class 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)

运行结果如下图所示：

这就是测试用例失败的样子。

希望本文所述对大家的Python程序设计有所帮助
