can you elaborate on http server instance?
I visited the docs and it shows that you only need the URL

URL works but it means my server is running in a separate process and i can't mock external calls

external calls are.. naturally in a separate process? wouldnt having it in a separate process mocks the scenario of external calls?

need to pass in the server instance like for example express()

but not sure for nextjs how it works

for example

i run a server in 1 terminal

then i run the tests in another

the tests make a call to the server's api lets say /getdata

that /getdata endpoint has logic that calls some other service somewhere unrelated to my app (external-api.com/getOtherData)

i dont want it to call that endpoint, i want to mock that response

ahh

if i could load and mount the http server instance and run the supertest tests in the same process then i could mock those

heres an example in strapi (https://strapi.io/blog/automated-testing-for-strapi-api-with-jest-and-supertest)

this doesnt use nextjs but i'm trying to do this on the nextjs application
