函数名需要 “test” 开头，才能被应用

Ran 0 tests in 0.000s 这个测试样例 没有 被应用

import unittest

class test_myClass(unittest.TestCase):
    # def testgetNameEmpty(self): ## 函数名需要 “test” 开头，才能被应用
    def getNameEmpty(self):
        self.assertEqual("love","peace")
        # self.assertEqual("love","love")

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

daiyi:daiyi$ python ./daiyi-b.py

OK

函数名需要 “test” 开头
Ran 1 tests in 0.000s 有一个测试样例被应用

import unittest

class test_myClass(unittest.TestCase):
    def testgetNameEmpty(self): ## 函数名需要 “test” 开头，才能被应用

python2 assertRaises 需要封装下

参考文章

import unittest

def func():
    raise Exception('lets see if this works')

class ExampleTest(unittest.TestCase):
    def test_error(self):
        # self.assertRaises(Exception,func())  ## 这个没有封装， assertRaise 不能抓取到这个 异常。
        # self.assertRaises(Exception,lambda:func())  ## lambda 封装后，能抓取到
        # with self.assertRaises(Exception): ## 封装后， 能抓取到
        #     func()

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