How to test nestjs modules?
Create a mock of the Repository that you're testing, it's the simplest one and the more cumbersome one, you can use a library like jest-create-mock-instance or jest-mock-extended or ts-auto-mock to create a mock from typings, but you're responsible to implement how it supposes to work.

Test interceptor
You can use something like jest-mock-extended or @golevelup/ts-jest to mock it, and whether your interceptor has dependencies or not, can be more complex or simpler how you instance it.

Nestjs + pnpm monorepo
To echo the other's here, Nx has been an amazing dev experience for me! I use it for ogma, for nest-commander, testing-nestjs, and for nest-samples and @nest-lab/, all using pnpm as a package manager.

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.

Any good tutorial showing you which library to use for dependency injection in a project?
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.
- Anyone who would be willing to show their sample repos?
