Question: How would you design a test strategy for a critical, high-traffic API endpoint?
Answer Framework: My approach would be layered. First, I'd ensure comprehensive contract testing using a tool like Pact to catch breaking changes in a CI/CD pipeline before they reach production. Next, I’d implement robust functional and integration tests covering positive/negative cases, authentication, and validation, running these against a staging environment that mirrors production. For performance, I'd use k6 or a similar tool to run load, stress, and soak tests to identify bottlenecks and define SLOs. Finally, I'd insist on production monitoring with alerts on latency spikes and error rates, combined with synthetic monitoring to proactively check endpoint health. This multi-faceted strategy ensures reliability from code commit to production traffic.
