Thanks for the docs! Do you think we can create integration tests with an example in the repo like we do for other integrations?

[productdevbook]

Where exactly are these tests ?

[ardatan]

Here we have examples for different integrations, Next.js, Fastify etc, and each of them have integration tests in the same folder.

Not sure if Apollo Sandbox is related?

Same with https://github.com/dotansimha/graphql-yoga/pull/3829/files#r1976794018

This is a different feature covered here;
#3654
I don't think Apollo Sandbox is related to Nuxt integration?
