Python--比较两个字典部分value是否相等（可以用于接口自动化）

Posted 2020-11-28 天空是我喜欢的颜色

eg:例如你调用了一个新增的接口，以往功能测试的话，你再web端新增一个店铺之后，你肯定要去数据库中查看，这些数据插入的对不对，是否正确的插入了每个字段

# 比较两个字典部分是否相等
def compare_two_dict(dict1, dict2, key_list):
    flag = True
    keys1 = dict1.keys()
    keys2 = dict2.keys()
    if len(key_list) != 0:
        for key in key_list:
            if key in keys1 and key in keys2:
                if dict1[key] == dict2[key]:
                    flag = flag & True
                else:
                    flag = flag & False
            else:
                raise Exception(\'key_list contains error key\')
    else:
        raise Exception(\'key_list is null\')
    if flag:
        result = \'PASS\'
    else:
        result = \'FAILED\'
    return result


if __name__ == \'__main__\':
    dict1 = {
        \'a\': 1,
        \'b\': 2,
        \'c\': 3,
        \'d\': 4
    }
    dict2 = {
        \'a\': 1,
        \'b\': 2,
        \'c\': 3,
        \'d\': 8
    }
    key_list = [\'a\', \'c\', \'b\', \'d\']
    result = compare_two_dict(dict1, dict2, key_list)
    print(result)

 

按照上面的列子我写出了自己的代码：前置条件：

但是有个前提条件：

 

 

\'\'\'
table:表名
key:要查找的字段名称
value：要查找的字段值
**kwargs：要检验的字段值，通过我新增的数据与数据库中的对比
例如你调用了一个新增的接口，以往功能测试的话，你再web端新增一个店铺之后，你肯定要去数据库中查看，这些数据插入的对不对，是否正确的插入了每个字段

    num = cursor.execute(sql)
    result = cursor.fetchall()
    print("查找到%d条数据" % num)
    print("数据库查询数据为：{}".format(result))
    # 这个是要对比的字段
    field_list = list(kwargs.keys())
    if num > 0:
        print("kwargs：{}".format(kwargs))
        print("result：{}".format(result[0]))
        flag = True
        keys1 = kwargs.keys()
        keys2 = result[0].keys()
        if len(field_list) != 0:
