Testing Offline First Mobile Applications
summary
Claim: make the UI read local storage first and let a background sync service update that store and push/pull changes automatically when the network returns. Concrete tools: Google Firebase AWS Couchbase REST endpoints, NSURLCache or HTTP cache with e-tag caching, and debugging via Charles or Wireshark. Numbers: prefer 2s on good networks, cap worst-case at ~10s not 60s. Built architecture reduces spinners and improves responsiveness but increases sync complexity and dependency handling; exercise the BART test for flaky transitions.
