Effective Strategies for Testing and Releasing Server Side Changes
summary
Advocates using the Swift compiler to catch bugs early, replacing Any dictionaries with protocols and enums to make config and refactors safe, and validating out-of-band JSON with schema checks at startup so bad configs fail fast. Recommends Swift macros to generate mocks, verifying call order when it matters and avoiding order checks for parallel calls. Uses localstack for AWS to run integration tests locally, runs linters AI reviewers unit and integration tests in CI, and rolls out with blue-green deployment and feature gates plus automatic rollback.
