REST Assured API Testing: Using Hamcrest Matchers to Validate Responses

“Hamcrest is a framework for writing matcher objects facilitating the creation of flexible and expressive tests in Java. REST Assured has first class support for Hamcrest matchers to validate headers and responses from APIs.

In this course you will explore the capabilities of the Java Hamcrest library a powerful tool for asserting various data types including numeric values strings collections and arrays with precision and flexibility. Next you will expand your testing repertoire by integrating Hamcrest with REST Assured for sophisticated API testing. Then you will learn to ensure API responses meet expected schemas and contents using Hamcrest matchers and lambda expressions. Finally you will discover how to specify path parameters in your URLs use unnamed and named parameters and specify query parameters for filtering the response. “
