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!
