From 3649e76c496ba7951eff4b94666e757ae36f9104 Mon Sep 17 00:00:00 2001 From: Matthew Date: Tue, 9 Dec 2025 02:46:13 -0800 Subject: [PATCH] feat(ios): add error handling and integration tests Implement comprehensive error handling and integration test suite: Error Handling (Section 8): - Add iOS-specific error codes to DailyNotificationErrorCodes: - NOTIFICATION_PERMISSION_DENIED - PENDING_NOTIFICATION_LIMIT_EXCEEDED - BG_TASK_NOT_REGISTERED - BG_TASK_EXECUTION_FAILED - BACKGROUND_REFRESH_DISABLED - Add helper methods for iOS-specific error responses - Enhance error handling in ReactivationManager: - Database errors handled gracefully (non-fatal) - Notification center errors handled gracefully (non-fatal) - Scheduling errors handled gracefully (non-fatal) - All errors logged, app continues normally - Partial results returned when operations fail - Update plugin methods to use iOS-specific error codes: - getNotificationPermissionStatus uses NOTIFICATION_PERMISSION_DENIED Integration Tests (Section 9.2): - Add DailyNotificationRecoveryIntegrationTests: - Full recovery flow tests (cold start, termination) - Error handling tests (database, notification center, scheduling) - App stability tests (no crashes, concurrent operations) - Partial recovery tests - Timeout handling tests - Test coverage: - 10 integration tests covering recovery scenarios - Error handling verification - App stability verification - Concurrent operation safety Completes sections 8.1, 8.2, and 9.2 of iOS implementation checklist. --- docs/IOS_IMPLEMENTATION_CHECKLIST.md | 46 +- ios/Plugin/DailyNotificationErrorCodes.swift | 69 +++ ios/Plugin/DailyNotificationPlugin.swift | 11 + ...DailyNotificationReactivationManager.swift | 85 +++- ...NotificationRecoveryIntegrationTests.swift | 468 ++++++++++++++++++ 5 files changed, 650 insertions(+), 29 deletions(-) create mode 100644 ios/Tests/DailyNotificationRecoveryIntegrationTests.swift diff --git a/docs/IOS_IMPLEMENTATION_CHECKLIST.md b/docs/IOS_IMPLEMENTATION_CHECKLIST.md index 511c3b4..bf177ba 100644 --- a/docs/IOS_IMPLEMENTATION_CHECKLIST.md +++ b/docs/IOS_IMPLEMENTATION_CHECKLIST.md @@ -381,22 +381,22 @@ Complete checklist of iOS code that needs to be implemented for feature parity w ### 8.1 Recovery Error Handling -- [ ] Ensure all recovery methods catch errors: -
