"TypeError: Cannot read property '_json' of undefined" with JEST + jest-openapi + PactumJS

[YauheniN]

Hello! Now I'm using supertest + jest-openapi for asserting that HTTP responses satisfy an OpenAPI spec. But I mainly plan to use PactumJS on a project for others assertions and have idea also use for this PactumJS. I'm trying to create assertion OpenApi like this:

const res = await pactum.spec().get('/account/stats').expectStatus(200);
await expect(await res).toSatisfyApiSpec();

And getting error: "TypeError: Cannot read property '_json' of undefined" . How send request or prepare response with PactumJS for assertion OpenAPI spec?

I have gone through the docs of jest-openapi. Seems the response object accepted by jest-openapi is different from what pactum returns.

This is an interesting use case and I would like to see pactum supporting these kind of assertions by default. I'm marking this as a feature request.

As a work around, this might do the trick.

const res = await pactum.spec().get('/account/stats').expectStatus(200);
res['_json '] = res.json;
await expect(await res).toSatisfyApiSpec();

Thanks for marking this as a feature request. It will be excellent). But your decision doesn't work in my case, I tried it earlier. Will be waiting support these kind of assertions by default.

Did you find the answer? I'm not sure it is related to PactumJS as I'm not using and have the same problem on calling .toSatisfyApiSpec().
