QA & SDET Handbook: Testing Distributed Core Banking
📖 Bản tiếng Việt (Vietnamese Edition) Series Navigation: This is Part 8 (Final Chapter) of the Core Banking Systems Architecture Masterclass. For the complete architectural curriculum, revisit the Master Overview Guide. QA & SDET Handbook: Testing Distributed Core Banking Answer-first: Testing distributed core banking engines requires moving far beyond conventional mock-driven unit tests. Because financial systems must guarantee strict linearizability, zero silent balance drift, and fault-tolerant continuous availability under arbitrary network partitions, Software Development Engineers in Test (SDETs) implement multi-tiered verification harnesses: deterministic concurrency testing via Go 1.24 testing/synctest, automated ledger invariant fuzzing, Consumer-Driven Contract (CDC) testing with Pact, Jepsen split-brain chaos verification, and production shadow traffic replay. ...
