21.七-测试两个整数相加

from calculator import Count#测试两个整数相加class TestCount:    def test_add(self):        try:            c=Count(2,4)            result=c.add()            assert(result ==6),'Integer addition result error!'        except AssertionError as msg:            print(msg)        else:            print('test pass!')# 执行测试类的测试方法test =TestCount()test.test_add()

结果：test pass!
