Write Once, Test Everywhere: Cross-Platform Testing for React Native
Cross-platform testing in React Native made simple: a lightweight architecture to run and extend tests on any JavaScript-powered platform.
Write Once, Test Everywhere: Cross-Platform Testing for React Native

As React Native evolves and expands to new platforms, ensuring consistent behavior across diverse environments is critical. Existing cross-platform testing solutions often lack flexibility, typically supporting only popular platforms like iOS and Android.
This talk introduces a lightweight testing architecture designed for React Native, enabling developers to run tests across multiple platforms efficiently.
We’ll explore its implementation, walk through writing tests, and demonstrate how easy it is to add support for any JavaScript-running platform with just a single file.
