Testing Library vs Pest
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

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.
- Much less boilerplate than raw PHPUnit for the same coverage.
- Architecture testing — enforcing layering rules as tests — is a genuinely useful addition.
- Fully compatible with existing PHPUnit tests, so adoption is incremental.
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.
- Another abstraction layer to debug when something goes wrong underneath.
- Strongest in the Laravel world; thinner elsewhere.
- Smaller ecosystem of examples than PHPUnit.
Best for
Any front-end team writing component tests, regardless of framework.
Laravel teams and modern PHP projects that find PHPUnit verbose.
