Yes, I am aware that this is what the recommendations suggest, but IMO tightly coupling language-based queries (byText, byLabelText, byAltText, byPlaceholderText, etc.) are more fragile and limiting when you wish to test other languages, for instance.
More so, when you write e2e automatons you find that having a non-dependent identifier makes life a lot easier. So If you're going to do that for e2e test, why not use the same data-testId for both purposes.
This is a discussion that also took place on twitter with Kent C. Dodds ( and I might submit a "call" just to make sure I understand what he's suggesting there.
