Hello! I’m new to Katalon. Tell me please is there a simple method to verify value of JSON response by “Is equal or greater than”? I see there is method which verify JSON value: WS.verifyElementPropertyValue(response, ‘total’, 0) But is it possible to use it to verify value by “Is equal or greate…

@Ibus , thank you very much! So thanks to all and with help of this post from @Ibus , the final steps and code for validating JSON response including if keys’ values are equal or greater than 0 are: At first let’s imagine you want to verify that response: { "total":6.98, "available":0.0, "pen…

Thanks for the method info! I know I can use OR statement. I meant isn’t there any other more simple way than using BigDecimal and compareTo() method to compare floating numbers which were gotten from JSON response?

There is always a better way how to do anything, but I am not aware of any. You’d still need to convert your JSON value to some object and compare it. Ultimately, I don’t think this is a difficult approach, I’d say it is quite easy.

@alexfeel a different approach will be to use Json schema validation. The field presence and value type verification is easier … and for values you can use exclusiveMinimum https://json-schema.org/latest/json-schema-validation.html#rfc.section.6.2.5

@Ibus thank you! I see there is more suitable minimum https://json-schema.org/latest/json-schema-validation.html#rfc.section.6.2.4 for my purposes. But how to use it in that code? Do I need to use that http://json-schema.org/implementations.html#validator-java ?

I made a post here, how i did it with everit-validator: [image] How to validate the JSON response with expected JSON schema Katalon Studio So, here’s my approach. First, I add some .jar’s into my project: [Image: https://s3.amazonaws.com/katalon-forum/editor/4b/vcidfae4…

[image] Ibus: JSON Schema validator for java, based on the org.json API - everit-org/json-schema Thanks! I give it a try later. I see schema looks like swagger API definition, maybe it’s possible to use that definition as validation schema?

I am not familiar with swagger definitions, but basicaly you need as follows: type - to check first if the response is an object and later for each field required - to check the field presence properties - where you describe additional validation’s for each field. So, putting all this together…

@Ibus thank you very much, it’s really good way to verify JSON responses!

[image] Marek_Melocik: Or - extract the verification step into a separate method. void verifyValues(BigDecimal jsonValue) { BigDecimal cbase = 0.0 if(jsonValue == null || jsonValue.compareTo(cbase) == -1) { KeywordUtil.markFailed("Key is not present or has incorrect value") } } verifyValue…

Response body: JSON value is equal or greater than

I made a post here, how i did it with everit-validator:

Unfortunately the sample code was malformed when the forum has been migrated to the new platform, but the implementation is based on the doc provided on git:

java-json-tools + jackson will work too.
