Tests cover: - Reconnection backoff delay behavior (5s, 10s, 30s cap) - Timer cancellation when servers reconnect - State tracking of disconnected servers - Rapid disconnection/reconnection events - Multiple servers disconnecting simultaneously - Edge cases (inactive managers, partial reconnection) Note: Tests document expected behavior but are limited by NetworkExtension framework constraints. The reconnection timer and attempt counter are private and tested via observable behavior. Co-authored-by: bgoncal <5808343+bgoncal@users.noreply.github.com>
- Add DEBUG-only test accessors to NotificationManagerLocalPushInterfaceExtension - Rewrite tests to use test accessors for direct state verification - Add tests for backoff delay calculation and timer state - Add tests for attempt counter increment and reset - Add tests for rapid schedule/cancel cycles - Document integration behavior and expected reconnection flow Tests now directly verify: - Reconnection delays array (5s, 10s, 30s) - Timer creation and cancellation - Attempt counter behavior - State transitions during reconnection - Edge cases like multiple attempts Co-authored-by: bgoncal <5808343+bgoncal@users.noreply.github.com>

Pull request overview
This PR adds comprehensive unit tests for the LocalPush reconnection logic introduced in PR #4113. The tests cover exponential backoff delays, timer cancellation, state transitions, and various edge cases to ensure the reconnection mechanism works correctly.
- Added 13 focused test cases verifying private reconnection state and behavior
- Introduced DEBUG-only test accessors to expose internal state without compromising production code
- Tests validate backoff calculation (5s, 10s, 30s cap), timer lifecycle, attempt counter behavior, and rapid state changes

This PR addresses feedback from the code review on #4113 requesting test coverage for the

Note: Due to NetworkExtension framework constraints (NEAppPushManager requires provisioning/entitlements), full integration testing requires Xcode environment. The unit tests verify all testable logic through internal accessors.
