Rest Assured: API Testing for REST Services

• Basic knowledge of REST API.
• Software testing experience in Java.

Audience

• QA engineers, testers and test developers involved in testing software and web service APIs

Testing and validating REST services in Java is harder than in dynamic languages such as Ruby and Groovy. REST Assured is a Java DSL (domain specific language) that brings the simplicity of these languages into the Java domain. 

In this instructor-led, live training, participants learn how to use Rest Assured to test REST API services. We discuss how API testing can resolve some of the shortcomings of UI and unit based testing. The training includes practice sessions and a test development project. By the end of the training, participants will have a good understanding of when to carry out REST API testing, how to explore and access APIs, how to carry out different types of testing, and how to bring their tests together through integration and automation.
