Integration tests

Integration tests validate behavior across module boundaries, especially where state, storage, and service adapters interact.

Scope

• Login/session flow with Firebase Google OAuth adapter
• Board loading and persistence with Firestore-backed services
• Speech pipeline from sentence builder to selected speech provider
• Service worker and cached asset behavior under offline conditions

Guidelines

• Validate end-to-end use-case slices from use-case-descriptions.md.
• Use controlled fixtures for boards, metadata, and prediction data.
• Stub external services when verifying client integration logic.
• Keep test output machine-verifiable and avoid manual interpretation in CI.

Priority Scenarios

• Sign in, sync metadata, and load user board
• Build sentence, update prediction context, and trigger speech output
• Execute an HTTP action and surface response to live elements
