Develop and maintain the overall test strategy, master test plan, estimates, scope, test levels, environments, data needs, entry and exit criteria, and reporting approach for Enterprise Pub/Sub application changes.
Review product, workflow, interface, and technical requirements; identify quality risks and coverage gaps; and maintain traceability from requirements through test scenarios, defects, and release evidence.
Design, automate, execute, and maintain API tests for publishers, subscription management, notification delivery, event retrieval, queue-based processing, downstream actions, and failure-recovery workflows.
Use Postman, NextGen API testing tools, and ngrok-hosted endpoints to validate REST APIs, external callbacks, rest-hook delivery, request and response payloads, headers, authentication, timeouts, and error handling.
