What do you want to know GRAPHQL + NESTJS ?
Question: for your e2e tests will you be using something like supertestto send the gql request? And if so, could I suggest you look at pactum which (in my opinion) has a stronger API and better gql support. I've got an example here if you need it

is it normal that service classes get really big?
Test files usually shouldn't be too large. You should just need a simple mock for each injected dependency for the service. You can see a lot of examples I have here. If you could show your test file it may help us figure out why it might be really large.

Then there's also a @nestjs/testing package that can be used for overriding these injections during tests to make for super easy unit testing (in my opinion) and a large repo of examples here.
