About This Course

This course covers API testing using industry-standard tools Postman and REST Assured. You'll learn to validate REST and SOAP web service interactions, execute HTTP requests (GET, POST, PUT, PATCH, DELETE), and write automated test scripts that verify response data and behavior. The training spans both GUI-based and code-driven testing approaches, equipping you with practical skills for real-world API quality assurance.

Designed for QA automation engineers and test analysts, this beginner-to-intermediate course takes you from sending individual API requests through to building complete, parameterised test frameworks integrated with continuous integration pipelines. You'll work with Postman collections and Newman command-line execution, then progress to writing REST Assured tests in Java using Maven, TestNG, and Cucumber for behavior-driven testing. By the end, you'll design reusable API test frameworks and automate comprehensive test suites ready for CI integration.
