fakeshop-api VS supertest

Integration test with jest and supertest E2E test with jest and Pactum

I've used k6 https://github.com/leosuncin/nest-auth-example/tree/master/stress-test and artillery https://github.com/leosuncin/fakeshop-api/blob/master/performance-test.yml

Supertest is quite popular and easy to use test tool, you can do integration and E2E test as well, you just need to pass it the server instance or a string to make a request and assert over the response.

If the latter, there are a bunch of different options for writing automated tests. One popular way is using Jest to run your tests. If you're trying to test the backend end-to-end flow, you could use Supertest to make requests and assert on the responses.

I did something similar with a full stack Typescript project, using supertest and node-fetch. It was nice.

Unit, Integration and E2E tests using Jest and Supertest

This is why integration tests > unit tests. I really hate mocking and I never bother testing individual units that don't affect how users use my app and code. In your case, I'd just use something like supertest to test this functionality e2e.

Yes, but when every function handler is separate from the router, then you can use node-mocks-http to test each handler, to test the router is simpler to use supertest to write integration tests, for E2E tests I personally recommend [pactum](pactumjs.github.io/)

Simple booking api attempt with Typescript, Express, TypeORM and Postgres. Testing with Jest & Supertest.

In a Node.js application, writing API tests is a good start. They provide more coverage than unit testing. You can use frameworks like Supertest, Jest, or any other library that provides a high-level abstraction for testing APIs.
