Description
The API Testing using Postman and REST Assured Certification program is designed for intermediate learners who want to master both manual and automated API testing. You will begin with Postman to build, execute, and automate requests, then move to REST Assured with Java for robust automation frameworks. This course emphasizes data-driven testing, CI/CD integration, and real-world projects, preparing you for careers in QA Automation, Test Engineering, and DevOps-enabled testing pipelines. By the end, you will have hands-on skills to design scalable API testing solutions for enterprise applications.
