Simplified way to ignore all data values when comparing two JSon responses

[mdpete...@comcast.net]

I'd like to compare the Json structure of two responses while ignoring data differences between the two. I was wondering what the simplest way to achieve that would be. 

Thanks,

Mike

Do you mean like a diff tool?

Hi Johan.  I mean, can I get just the path of the elements  in a Json tree. That way I could make sure the trees are the same even if data is different. I want just the element names. I want to do something like this but without going outside rest-assured and JsonPath:

Hi,

If I understand you correctly you can do something like this:

expect().

            body("x.y.z", not(nullValue())).

            body("x.y.z2", not(nullValue())).

when().

           get("/something");

If you already have a JSON document you could using JsonPath:

Object value = from(json).get("x.y.z");

assertThat(value).isNotNull();

Regards,

Hi. My real goal is to compare the trees of the two objects while not considering what values each node has. The reason for this is that I'd like to have a boolean in my test that when True will generate a file from the response. Then I will change it to False and compare the names of each path node in my actual response to those in my saved file. I don't want to bring the values (the data) of the [ath nodes into the picture into the picture. My goal is to check that the structure of the JSon is the same in both. When I find that they don't match any more, I can determine if there's a bug or a deliberate code change that changed the Json structure. If the change is not a bug, I will regenerate the file to get a new baseline response. I'm hoping this type of test will save time on test maintenance and make things less brittle. It is similar to the type of thing I want to do in my other post where I'm comparing a baseline file to a response but in this case, I don't want to consider the data in my comparison of the response and the file.

Maybe a simpler way of saying this is that I want to compare just the keys of each key:value pair in the Json responses. I'd like a simple way to get jsut the hierarchy of the keys for the entire response.

Ok I think I get it. Unfortunately there's currently no good way to achieve this with RA or JsonPath.

Thanks. I just found a way to do this. Haven't done much with it yet, but seems to do what I want. 

I'm using the org.json.JSONObject and JSONArray classes. The JSONObject class has a names() method that returns the list of key names for a JSONObject. Here's the code I'm using to get the key names of of the Json objects in an array in my response:

JSONObject resObj= new JSONObject(res);

JSONArray jsData = jsObj.getJSONArray("data");

JSONObject dataObj = (JSONObject) jsData.get(0);

JSONArray fields = dataObj.names();

Thanks for sharing, glad you found a way to solve it.
