Flaky-test diagnosis, parallel isolation, external dependencies, and trustworthy CI feedback.
Practice items tagged with Test Suite Reliability.
Designs realistic load, stress, spike, and soak tests from workload assumptions and SLOs while correlating client results with server bottlenecks.
Uses unique namespaces and correctly scoped fixtures so parallel tests improve speed without creating collisions.
Treats flakiness as an observable defect in timing, state, order, infrastructure, or product behavior.
Designs a reliable CI test system with fast feedback, deliberate test stages, bounded parallelism, visible flakiness, useful diagnostics, and clear ownership.
Tests durable background processing across duplicate delivery, retries, acknowledgement timing, crashes, poison messages, and observable completion.
Combines protocol stubs, contract checks, sandbox tests, and failure simulation without depending on live production services.
