compare a response with a json file

[kaivi]

Hey,

first of all i have a GET request with a response... now i wanna save the response in a JSON file to compare this with a existing JSON file.

HOW can i do this?

best regards

kai

This should be simple to do. But just to clarify before giving an answer:

1. If you want to compare the response with an existing content of a file why do you want to save the response to a file. Wouldn't it be simpler to just read the content of the initial file and compare it directly with the current response.

2. I am not aware of the full context of your test but I generally see this kind of tests unreliable. If something is to change in the response you may have to do a lot of rework.

1.Yes. Is that possible?

2. True!

i found some Code and it works but maybe u can help me. If there is a Mismatch there is only a log.info and the test continues with "PASS". Is taht possible to say is there a mismatch the test failed?

import groovy.json.JsonSlurper
def filePath = "C:/qwerty/test.json"
def jsonResp = context.expand('${GET ProCon#Response}') 

def outputResp = new JsonSlurper().parseText(jsonResp)
def baselineResp = new JsonSlurper().parseText(new File(filePath).text)

baselineResp.each{

    if (!(it.value == outputResp[it.key]))
    {
        log.info ("File Mismatch at : " + it.key)
    }

}

You can use a keyword assert i.e assert expected == actual 

[Lucian · Accepted solution]

You can use the following code:

...
if (!(it.value == outputResp[it.key]))
    {
        log.info ("File Mismatch at : " + it.key)
        testRunner.fail( "File mismatch..." )
    }
...

@Lucian
it works.
and now my next question. i have a [] in my json. Is there a error/mismatch in the [] let me take a example... lets say i have Items[] and in Itmes i have a OID = 123456, Name = XYZ for now the test can say me there is a error/mismatch in ITEMS but not where. It cant say error or mismatch in Items>OID.


@jhanzeb1

im complity new to groovy where i need to add "assert i.e assert expected == actual" and did i need to delete anything?

assuming you hit the if condition you mentioned you should just be able to use

assert (it.value == outputResp[it.key])

if it passes, it wouldn't have hit your if so nothing would have been logged out, but if it fails it will hit the if and subsequently fail this assertion

Hope this helps,
