🧪 Implement Complete Test Cases for Every Component, Hook, Utility, API Flow & Desktop Workflow

Start by reviewing the existing project structure and package configuration, then inventory the components, hooks, services, desktop flows, and current CI before creating vitest.config.ts, playwright.config.ts, src/test/setup.ts, and .github/workflows/test.yml. Done means the named unit, integration, E2E, desktop, accessibility, performance, security, and platform coverage requirements are implemented and the stated thresholds are enforced in CI.

CommDesk currently lacks exhaustive automated testing coverage across the application architecture.

This issue introduces a complete enterprise-grade QA ecosystem where every:

• Component

• Hook

• Utility

• Service

• Store

• API flow

• Feature module

• Permission flow

• Tauri integration

• Auto-update workflow

• Desktop interaction

must have production-grade automated test coverage.

This issue upgrades the testing system from partial coverage to a fully scalable, maintainable, CI-enforced testing architecture.

Reference QA standards:

🎯 Main Objective

Create a production-grade testing infrastructure where:

✅ Every component has unit tests
✅ Every hook has tests
✅ Every utility function has tests
✅ Every feature flow has integration tests
✅ Every critical workflow has E2E tests
✅ Desktop-specific features are validated
✅ Cross-platform behavior is verified
✅ CI blocks broken PRs automatically
