How to test custom nestjs provider?

[RWOverdijk]

Hi!

I have a custom provider that uses a Symbol as the key, and returns a non-class type (a fetch client). The typing makes me think I am not allowed to?

I've already gotten the exact same provider using unitRef, which worked great:

beforeAll(async () => {
  const { unit, unitRef } =
    await TestBed.solitary(SomeService).compile();

  client = unitRef.get(SomeClientProviderKey);
  service = unit;
});

But now I want to do something like this:

const { unit } =
    await TestBed.solitary(SomeClientProviderKey).compile();

And it's not letting me, saying it is not assignable to type Type.

Basically this: https://suites.dev/docs/developer-guide/adapters/identifiers but the closest example there uses a symbol to resolve a mocked (unitRef) instance. I want the actual thing.

I've solved this by using nest's testing utilities instead. But I am still curious how I could do the same with suites :)
