Does Pactum support JsonPath assertion?

[mihirsasmal]

When you have large Json with huge list of similar arrays in that json, verifying a value with reference from another data will help.
Using Jsonpath (please refer "https://goessner.net/articles/JsonPath/ ") we can verify it easily.
Does pactum support Jsonpath ?

If not then , is ther any way to assert data with reference to another data in a json ?

Almost all assertion methods support JsonPath provided by json-query. Please refer the docs

Thanks! But how to test a JSON don't have a certain field? I tried with:

				.expectJsonMatch({
					header: {
						note: "$V === undefined"
					}
				})

But it complains that Json doesn't have property 'note' at '$.header'.
The workaround is to use jest:

				.expect((ctx) => {
					expect(ctx.res.json.header).not.toContainKey("note");
				})

But seems to me I'm going back to jest too much.
Could some form of expectNotSomething() to be added to Pactum?
Thanks for clarifying!

It's easy to use notIncludes to assert such conditions.

const { spec } = require('pactum');
const { notIncludes } = require('pactum-matchers');

await spec()
  .get('<url>')
  .expectJsonMatch({
    "header": notIncludes("note")
  });

Thanks, ASaiAnudeep for the reply.

I was using all the assertions mentioned in docs but trying to use Jsonpath usages based on this "https://goessner.net/articles/JsonPath/ " that's why it wasn't working for me.

After exploring json-query based Jsonpath from your suggestion and docs , I believe its the easier and best way to find jsonpath than using the xpath like syntax from "https://goessner.net/articles/JsonPath/ " and using any online json path finder.

Thanks
