A focused 30-day roadmap to master API testing concepts, tools, and frameworks. Covers Postman, Newman, RestAssured, Python Requests, JMeter, authentication, security, performance, and real-world challenges.
API Testing ensures the reliability, functionality, performance, and security of backend services that power modern applications. Unlike UI testing, API testing validates business logic directly, making it faster, more stable, and essential for microservices and cloud-based systems. This roadmap provides a structured journey from basics to advanced concepts in API testing, equipping QA engineers with hands-on skills in Postman, Newman, RestAssured, Python Requests, JMeter, and service virtualization.
Ensures APIs return correct responses, handle errors, and integrate properly.
Enables early testing of services before UI is ready.
Runs faster than UI automation with fewer flaky failures.
Critical for microservices, DevOps, CI/CD, and a core SDET skill.
