Integration tests (tests/): - 9 categories covering config, lifecycle, signals, supervision, cache, writeback, network faults, crash recovery, and CLI - Shell-based harness with mock NAS (network namespace + SFTP), fault injection (tc netem), and power loss simulation - TAP format runner (run-all.sh) with proper SKIP detection Rust unit tests (warpgate/src/): - 110 tests across 14 modules, all passing in 0.01s - Config parsing, defaults validation, RestartTracker logic, RC API response parsing, rclone arg generation, service config generation, CLI output formatting, warmup path logic Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
