Pull request overview
This PR adds a shared Jest-based test suite that can be executed across the demo apps in apps/, and wires up each app’s Jest configuration to run those shared suites. It also updates Turbo/task wiring and docs to support running app tests from the repo root.
Changes:
- Added a new
apps/brownfield-example-shared-testsworkspace exporting reusable Jest suites + shared Jest setup/mocks. - Added Jest configs/setup and new shared-suite test entrypoints for
RNApp,ExpoApp54, andExpoApp55(plustest:appsturbo script and CONTRIBUTING docs). - Adjusted Turbo dependencies (
build:brownfield) and package scripts to ensure needed builds happen before lint/typecheck.
