Add unit tests for HistoryViewModel search and filter logic

[vssinghh]

🎯 Summary

The project has solid unit test coverage for AIEngineImpl, EvaluateNotificationUseCase, ParseCommandUseCase, and ChatViewModel, but the HistoryViewModel currently has no unit tests. Add tests for its search/filter functionality.

📍 Where to Look

• app/src/main/java/com/hush/app/ui/screens/history/HistoryViewModel.kt — The ViewModel to test
• app/src/test/java/com/hush/app/ui/screens/chat/ChatViewModelTest.kt — Example of how ViewModels are tested in this project (use as a pattern reference)

✅ What to Do

1. Create a new test file: app/src/test/java/com/hush/app/ui/screens/history/HistoryViewModelTest.kt
2. Write tests covering:
   • Initial state has empty search query
   • Setting a search query updates the filtered logs
   • Search filters by app name, title, and text content
   • Empty search query returns all logs
   • Search is case-insensitive
3. Mock the HistoryRepository dependency (follow the pattern in ChatViewModelTest)

🧪 How to Verify

./gradlew testDebugUnitTest --tests "*.HistoryViewModelTest"

All tests should pass.

📚 Resources

• Look at ChatViewModelTest.kt for the project's testing conventions
• Testing Kotlin Coroutines
• Testing StateFlow

Great way to learn the project's architecture by writing tests for it! 🙌
