this might be a bit unstable, how about expectedError error and then asserting errors.Is(err, test.expectedErr)?

Why do you think this would be unstable? require.EqualError takes in a string as a second argument. I thought it was meant to be used this way?

right, but we ever change the exact wording of the error message, this test will break. versus if we just assert on the type of error being returned, it is more stable

Oh I understand now! We want to assert on the type of error. I explored this possibility today, but unfortunately that won't work for this case. Because we are returning the error as fmt.Errorf("duration: %v is out of range for time.Duration", dpb) it doesn't have a specific type that we can assert on. Plus I want to ensure we error out with the correct message and not with a different message that doesn't make sense.
I think for now this is fine and if we change the error message, then we should also change the expectations of the test.
