Why `testTag` is part of the semantics tree? Why it’s not a separate entity?

Been asking myself this for a while too. It feels wrong for this to be part of production code

I am fine with testTag in production. My concern is only around testTag being part of the semantics tree.

Anyone can call `clearAndSetSemantics` from top layer for some a11y support and that may destroy the testTag, in turn break tests.

<@ULERY2F70> can you elaborate the problem u faced of having testTag in production?

Well for me, its not really a problem perse (found none at all), its just that. We have main source sets and test source sets for a reason. if we start putting test information into our main source sets, the line of distinction becomes blurrier between the two

I think my problem can be fixed by using the flag `useUnmergedTree` :slightly_smiling_face:
