Mastering REST Assured for REST API Test Automation
(including Maven and JUnit) - 21 hours

Concepts

This practical course offers comprehensive knowledge on REST API test automation, employing the widely acclaimed Java library, REST Assured. Participants will gain insights into the functioning of the HTTP protocol and the principles underlying the REST design pattern. The course covers scripting for automating HTTP communication, both with and without Gherkin language integration within REST Assured. Participants will also learn techniques for validating JSON response values. Within Maven projects, you'll integrate REST Assured with JUnit, a renowned framework for unit and functional test automation, enabling the creation of efficient scripts.

Audience

This comprehensive course is designed for individuals aiming to leverage their Java skills for the highly sought-after profession of test automation engineering

Pre-requisites

Proficiency in Java with IDE of your choice (Eclipse is preferred)
We recommend completing our course “Mastering Java for Testers.”
