NUCLEAR EXPANSION: systray_test.go 0→707 lines, 0→20 tests!
Created comprehensive test suite for previously UNTESTED systray package (801 lines). Pure Function Coverage (8 tests): - profileTitle: Cross-platform title formatting (Windows/Mac/Linux) - countryFlag: 2-character to emoji flag conversion (🇺🇸, 🇩🇪, etc.) - Unicode validation for regional indicator symbols Mullvad Exit Node Logic (7 tests): - newMullvadPeers: Country/city organization from peer status - Priority-based peer selection (highest priority = best) - Multi-city countries with submenu generation - Sorting: countries by name, cities by name - Edge cases: empty status, non-exit nodes, missing locations State Management (3 tests): - Menu.init(): Channel and context initialization - Menu.onExit(): Cleanup without panics - Double-init safety (idempotent) Integration Tests (2 tests): - Real-world scenario: 3 countries, 5 cities, multiple peers - Priority selection across countries/cities - Sorting verification Coverage Categories: ✅ Country flag emoji generation ✅ Profile title formatting (platform-specific) ✅ Mullvad peer organization by location ✅ Priority-based "best peer" selection ✅ Alphabetical sorting (case-insensitive) ✅ Menu initialization & cleanup ✅ Edge cases: empty, invalid inputs BEFORE: 801-line file, ZERO tests AFTER: 707 lines of comprehensive test coverage!pull/17963/head
