I am comparing JSON responses from two different servers. They should basically match but due to caching, there are some small differences in fields such a temperature, wind speed, etc.
I am currently using a customization to ignore certain fields that always fail like this:
JSONAssert.assertEquals(response2.getResponseBodyContent(), response1.getResponseBodyContent(),
new CustomComparator(JSONCompareMode.LENIENT,
new Customization("**.TimeStamp", {a, b -> true}),
new Customization("**.EpochTime", {a, b -> true})
));
Questions:
- How would I go about specifying a range (temperature can be within 10)?
- How to specify that the value only matches a certain type (string, integer)?
JSON Samples:
JSON 1
"Temperature":{
"Metric":{
"Value":4.6,
"Unit":"C"
},
"Imperial":{
"Value":40.0,
"Unit":"F"
}
},
"Wind":{
"Direction":{
"Degrees":293,
"English":"WNW"
},
"Speed":{
"Metric":{
"Value":19.4,
"Unit":"km/h"
},
"Imperial":{
"Value":12.1,
"Unit":"mi/h"
}
}
JSON 2
"Temperature":{
"Metric":{
"Value":5.1,
"Unit":"C"
},
"Imperial":{
"Value":43.0,
"Unit":"F"
}
},
"Wind":{
"Direction":{
"Degrees":271,
"English":"ENE"
},
"Speed":{
"Metric":{
"Value":19.9,
"Unit":"km/h"
},
"Imperial":{
"Value":12.4,
"Unit":"mi/h"
}
}
I am using a testing tool called Katalon which supports groovy/java. Any help would be greatly appreciated. Thanks!
I don't know Katalon, but I can take a good guess at how to fix this based on the code you've shown. This code:
is providing a closure that compares any two TimeStamp nodes, passed as
a
andb
, and always returnstrue
. That effectively ignores TimeStamp (and EpochTime) in the comparison.To achieve what you want, you just need to supply a version of that closure that performs the check you want.
To return true if the times are within ten seconds, you might do:
for example. You'll need to check the appropriate values for your data - TimeStamp is probably a text string that you'll need to parse into a suitable Date object first.
The closure can have multiple lines of code, and can be defined separately:
(This isn't tested code and won't work as written; it's just to give the flavour of how your solution will look).
