jest-expo 55.x is likely incompatible with the project's Expo SDK (~54.0.0) and it also brings Jest 29.x tooling in its dependency tree. Adding jest@^30.3.0 here can cause version/peer-dependency conflicts (and may make the jest binary resolve to the wrong implementation). Align jest-expo to the Expo major version and use the corresponding supported Jest version (or rely on jest-expo’s bundled Jest).

ts-jest is added as a devDependency but the Jest config uses the jest-expo preset and does not configure ts-jest as a transformer. If you’re not explicitly using ts-jest, it’s better to remove it to avoid extra dependency weight and potential Jest version alignment issues; otherwise, configure Jest to actually use it.

This adds Jest dependencies but package.json still has no test/test:watch script, which makes the new test suite hard to run consistently (and easy to miss in CI/local workflows). Consider adding a test script that invokes Jest with this config/preset.
🎯 What: The centralized error handler (
src/utils/errorHandler.ts) lacked unit tests, creating a gap in verifying our primary error reporting mechanism.📊 Coverage: The new test suite covers:
Errorobject handling (console + UI alert).silent = truebackground execution path (ensuring no UI alert is triggered).✨ Result: Increased test coverage for our core utility, ensuring confident refactoring and reliable error reporting without regressions. Also properly scaffolded Jest for the React Native/Expo project environment.
