v0.0.3 — Experimental preview

Warning

Experimental. Ennio is at an early experimental stage. APIs, package
names, internals, and behavior may change without notice between releases.
iOS only. Expect rough edges; do not rely on it for production-critical test
suites yet. The 0.0.x line is a public preview, not a stability commitment.

First tagged release of Ennio — a Maestro-compatible E2E test runner for
React Native iOS that drives the app over Hermes Inspector (CDP) and actuates
real CoreSimulator touches via a persistent idb HID daemon.

Install

bun add @reactiive/ennio react-native-nitro-modules
bun add -d @reactiive/ennio-expo-plugin

Then add "@reactiive/ennio-expo-plugin" to your app.json plugins,
npx expo prebuild --clean, npx expo run:ios, and write a Maestro YAML.
Full walkthrough in the README.

Limitations

• iOS only. Some Android scaffolding exists in the source tree but no
  runtime, no JNI hook, no JS-thread executor. Adding the plugin to an
  Android-only build is a no-op.
• Metro must be running. With no Metro, there is no Hermes Inspector to
  connect to; the CLI errors out immediately.
• Bridgeless / Fabric only. Old-architecture RN is not supported; the
  shadow-tree traverser and the React-commit hook assume the new arch.
