Great video. The expected responses and requests using a json file with base 64 encoding was genius

@@snagananda696 Thanks, glad it helped.

[@a.v.sanchez9193]

Thank you. This is tremendously helpful! I highly recommend this tutorial to anyone testing an api with a microservice architecture.

[@vdespa]

Thanks ☺️

[@hugfil]

Great video, thanks. Can you tell me if the test passes in the case that the responses are identical but in a different order?

[@rohithkumar9120]

Is there a way to validate the two response with dynamic change in values without delete?

[@FiRese7eN]

Great videos dude. They are very helpful and clear! Thanks.

[@vdespa]

Thanks. I am glad they are useful!

[@teleport96]

Thanks for the video! Tell me please, where I can find documentation about "delete" word in the Tests section? Maybe there are other "functions" I can use because I see this way of deleting props from the response in Postman for the first time. Thank you in advance.

[@vdespa]

Thanks for watching. I forgot to mention: this is simply a Javascript functionality, has nothing to do with Postman itself.

@@vdespa Hello, first of all congrats! Awesome video. I was trying to find a documentation on the delete too, I was trying to use it here, however I keep receiving a TypeError: Cannot convert undefined or null to object, whereas if I comment the delete line I receive the response. Any thougts of what I am doing wrong? const response=pm.response.json(); delete response.headers['uomId','quantity','totalValue','tax','cost']; pm.globals.set("expectedResponse",response); console.log(btoa(pm.response.text()));

How can I show different values ​​of 2 responses?

[@vdespa]

I am not sure what you mean by that. Could you share more details?

Sir How to Get Body Data?????????

[@HaiderAli-wt4jp]

Sir, Plz Give me an Answer

[@srida999]

Thanks but I am looking for a tool/code that does comparison on the fly by taking runtime traffic(queries). My project cannot rely on canned queries, since queries change all the time. Any tips or advice appreciated. I plan to develop the code myself (2/3 on a 10 in coding), but if i can find some tips, that would help.

[@vdespa]

Have you looked into just defining a JSON schema to test the structure of the response?

[@helpothers6751]

Hi Valentin, I am storing one response data in an environment variable, and the same data I need to compare in multiple API responses, please help me here.

[@vdespa]

Did you manage to replicate the example I've shown in the video?

[@helpothers6751]

Some multi-array

[@samroy4893]

Hi Valentine, could you please help me that how can we compare two JSON responses in which values of the Keys are same in both responses but "Key" names are different....for an example key is "workId" in one response and in other response key is "id" , but both key having the same value "2342" and there are 250 key pair values that we have to compare.....hope you help me out..thank you.. really appreciated!!!!!

[@cva1119]

Hi, how can we compare both responses irrespective of order of the elements

[@vdespa]

The test will still pass or fail. But if it fails, it will be hard to do a diff.

[@michalisbelomatis3042]

@@vdespa You mean that we don't have to sort the JSON responses? If they are identical but not in the same order, the test will pass?

[@ravinadhb9219]

Hi Valentin very good explanation. I have a question here . How do we add extra Object to the response and send it as request body to another API Request

[@vdespa]

You save it to a Postman variable and reuse it in the next request.

[@markthomas9641]

Thanks, good video. I use a tool called DeltaJSON to compare JSON responses from Postman API. It has an API that I can use from my code as well.

[@vdespa]

Thanks for sharing!

[@ranithomas3006]

Very good explanation Valentin. Is there any solution to compare with request body values and response body values of the other request?

[@vdespa]

You can write assertions using pm.request and pm.response to get the data you need.

[@blasterino]

Hi Valentin, thank you very much for your videos they are very useful. As a tip to compare I use sublime text + filediffs plugin. I have a doubt, how would I delete a field if I don't have headers like args or data as your example json has. Thanks in advance

[@vdespa]

Thanks for sharing! You can use the delete keyword on any property of an object.

[@blasterino]

Thank for you qickly response

[@Eswar1234eswar]

Thank you very much.

[@vdespa]

You're welcome ☺️

[@JC-ov8ko]

I use VS code to compare files locally so I am not exposing any important data. Also it color codes the differences.

[@vdespa]

Thanks for the tip, good idea!

[@ranimolthomas717]

Hi Valentin , It is very useful topic and Nice presentation. I faced one issue. can you please help me. While comparing two response body, am getting the error like Response must be like v1 | AssertionError: expected { Object (isChildExist, doNotRelease, ...) } to deeply equal [ Array(1) ] , even if the boolean values are same ( isChildExist & doNotRelease has boolean value). How can solve this issue. I used this - pm.expect(responsev2).to.eql(responsev1);

[@vdespa]

It looks like you are comparing an object with an array.
