Strengths

Tests survive refactors because they assert on user-visible output, not internals.
Accessible-role queries push teams towards accessible markup as a side effect.
One idiom across every major front-end framework.

Limitations

Deliberately makes implementation-detail testing hard, which frustrates teams used to shallow rendering.
Async utilities and act() warnings are a common source of confusion.
Needs a runner and a DOM environment alongside it.

Best for

Any front-end team writing component tests, regardless of framework.

Existing Angular codebases and browser-native test setups.
