React Native Harness: Deep Dive
React Native Harness: Deep Dive
Discover how React Native Harness enables fast, reliable testing of native modules directly on real devices. Learn how to write Jest-style tests, integrate them into CI/CD, and catch up on the latest updates from the React and React Native ecosystem.
React Native Harness: Deep Dive
Testing native modules in React Native just got a lot easier. In this live stream, Callstack engineers Szymon Chmal, Łukasz Chludziński, and Kewin Wereszczyński will introduce React Native Harness: a new framework that lets you run Jest-style tests directly on a real device or emulator.
You’ll see how Harness works under the hood, write your first test live, and learn how to integrate it into CI/CD to validate real native behavior without complex E2E setups.
As always, we’ll also cover the latest React and React Native community updates.
If you’re building or maintaining React Native libraries, this is the testing workflow you’ve been waiting for. Join us to see it in action.
