Open API 3.0 schema support in PostmanTiny validator

[LiamC (Liam Cooper)]

Hi,

I was wanting to do something similar recently, ended up getting it to work with Ajv validation instead, this topic might be helpful to you:

Testing Properties and Arrays correctly in GET

I managed to get something to work, after banging my head against a wall for hours. I do agree this schema validation stuff may be a lot more than I can handle at the moment, so I may go back to what I had originally. It’s been a learning experience though! If you’re interested by the way, this is what I found would actually test Passes & fails correctly: const jsonData = pm.response.json(); pm.test('Schema is valid', function() { var Ajv = require('ajv'); ajv = new Ajv(), schem…

@danny-dainton has a more concise example here of Ajv validation if that’s all you’ll need:

Hey @Coxjeffrey, I would recommend using Ajv over tv4, this also comes as part of the Postman app. You can use this example to check your response against the schema: var Ajv = require('ajv'), ajv = new Ajv({ logger: console, allErrors: true }), schema = { "type":"object", "required":[ "Id", "Progress", "Status", "Info", "Created", "Ended", "Operation", "Requested" ], "properties":{ "Id":{ "$id":"#/properties/I…

I ended up ditching Schema validation and testing it a different way as the API I’m testing has become really complicated and the schema way was just a bit too advanced for me to do for now.

Good luck, hope this helps!
