How Realm by MongoDB is Testing Native Modules “on device”
Running tests on Node.js is common practice for app and library developers. But when your library is integrating more deeply with the platform, operating system or JS engine, you need to run tests “on device” increases. The Realm JS team at MongoDB is faced with this challenge, as we’re maintaining a React Native library with native modules. In this talk I’ll share the “mocha-remote” package which we’ve built to help us run tests “on device” while getting reporting and remaining in control from the comfort of our terminals.
