deepdiff

deepdiff是一个校验两个对象是否一致的库，并返回其中的差异之处   文档

在校验接口返回值与预期值的差异，可以直接用作接口测试中的assertion

Deepdiff  递归查找所有不同项，增加、减少、修改等

拿两个json进行比较

from deepdiff import DeepDiff
import pprint


a =  {"Object":{
        "code": "0",
        "message": "success"
    },
    "code": "0",
    "message": "success"
}

b =  {"Object":{
        "code": "0",
        "message": "failure"
    },
    "message": "success",
    "timestamp": "1614301293"
}

pprint.pprint(DeepDiff(a, b))

结果

{'dictionary_item_added': [root['timestamp']],
 'dictionary_item_removed': [root['code']],
 'values_changed': {"root['Object']['message']": {'new_value': 'failure',
                                                  'old_value': 'success'}}

指定key不去匹配

from deepdiff import DeepDiff
import pprint


a =  {"Object":{
        "code": "0",
        "message": "success"
    },
    "code": "0",
    "message": "success"
}

b =  {"Object":{
        "code": "0",
        "message": "failure"
    },
    "message": "success",
    "timestamp": "1614301293"
}

pprint.pprint(DeepDiff(a, b, exclude_paths={"root['timestamp']", "root['code']", "root['Object']['message']"}))

结果

{}
