Could you please reuse the existing enum flags and adapt the test methods.
I've recently removed the repeated enum flags that where there.
There is no point on adding new enums just because... If the one there is suitable for the test lets use it. DRY and KISS, please. 😉

I need two enums because this test requires two separate enum types.
I could reuse the existing enum instead of one of them but that will make the test less readable because the second enum still has to be defined somewhere. Should I do this even so?

I've missed your point on using 2 enums. Now I can see that.
Then please "duplicate" the existing enum and do exactly what you're doing. This was that second enum will be available for news tests than need some something similar.
Does this make sense to you?

Done
