About this course

In a world driven by microservices and web-connected applications, the ability to thoroughly test APIs is an essential skill for every software professional. Ensuring that data flows correctly between systems is no longer optional; it is the foundation of high-quality software delivery. This course provides a comprehensive roadmap for understanding RESTful services and automating the testing lifecycle. You will transform from a beginner into a confident tester capable of validating complex interfaces and integrating those tests into modern development pipelines. What you'll learn: - Understand foundational API concepts, including REST architecture, CRUD operations, and HTTP status codes. - Master manual testing techniques to send requests and inspect responses using the Postman interface. - Write automated test scripts in JavaScript to validate data integrity, schemas, and response headers. - Organize testing workflows with collections, environment variables, and request chaining for complex scenarios. - Implement data-driven testing strategies to run high-volume validations using external data sets. - Automate test execution within CI/CD pipelines using Newman and Jenkins for continuous quality assurance. - Practice generating professional execution reports and mocking services to simulate real-world environments. The course begins with core terminology and basic request handling before moving into advanced scripting, environment management, and full pipeline integration. You will read through detailed explanations and apply your knowledge through practical written exercises designed to simulate real-world testing challenges. This course is built for beginners in software testing or development who want to master API automation from the ground up. No prior experience with testing tools or scripting is required to get started. Begin your journey into the essential world of API testing and automation today.
