Reassure is a performance testing library for React and React Native that automates performance regression testing. It measures render duration and counts across repeated runs, applies statistical analysis, and generates human-readable reports for CI or pull request comments.

Use cases

• catch performance regressions in react native apps automatically
• write performance tests alongside react native testing library tests
• measure render duration and render counts of react components
• run performance regression checks on CI for pull requests
• benchmark function and async function performance in javascript
• compare performance between stable branch and code changes

When to choose

• you maintain a React or React Native app and want automated performance regression detection
• you already use React Native Testing Library and want to extend tests into performance tests
• you want statistical significance analysis rather than single-run benchmarks
• you need performance reports posted to pull requests via CI

When to avoid

• you need deep profiling like flame graphs or CPU sampling from a profiler tool
• your project is not React or React Native
• you need load or stress testing of servers rather than component render performance
