Manjyot Singh and Ruchika Rawat gave an introduction to API testing using REST-Assured. They discussed the basics of REST and SOAP web services. REST-Assured was presented as a Java DSL for testing RESTful web services, allowing users to make HTTP requests and assertions on the responses. Examples were provided for common requests like GET, POST, PUT, and DELETE. Response parsing and authentication were also demonstrated. Other tools were mentioned and references provided for further reading.
