looks good, thanks for working on it 🙌

The current assertions fit in with the rest of this test, but long-term it may be simpler to use sinon assertions. that's non-blocking though, could be a good-first-issue follow-up. 🙂

[pichlermarc]

nit: we could probably use

Sinon.assert.notCalled(setGlobalTracerProviderSpy);

for this type of assertion.

[david-luna]

I kept using assert so we keep the error message but I agree maybe it's not necessary.

[pichlermarc]

nit: we could probably use

Sinon.assert.calledOnceWithMatch(
        setGlobalTracerProviderSpy,
        (arg: any) => {
          return arg instanceof NodeTracerProvider;
        }
      );

for this type of assertion.
