//! GRASP-02 Phase 2: Multi-Relay Proactive Sync Integration Tests
|
||||
//!
|
||||
//! Tests the multi-relay proactive sync functionality.
|
||||
//!
|
||||
//! Note: Integration tests for sync timing are inherently flaky due to
|
||||
//! subprocess communication latency. Unit tests for FilterService and
|
||||
//! SyncManager cover the core logic in src/sync/filter.rs and manager.rs.
|
||||
//!
|
||||
//! # Running Tests
|
||||
//!
|
||||
//! ```bash
|
||||
//! cargo test --test proactive_sync_multi
|
||||
//! ```
