API Testing Using Rest Sharp (with C#) Test Automation Tool

API stands for Application Programming Interface which helps two independent software to communicate with each other. When an application is built, the functionalities are built first as APIs and then integrated with the frontend layer (UI). Waiting for integration to find bugs in the application will add a lot of costs. The later the bugs are found in the system, the more cost it adds to the application.API Testing helps reduce the cost as it will be performed before integration with frontend (or UI). RestSharp is one of the best test automation tools to test APIs with C# programming language. It's an open-source tool and is very easy to code using Rest Sharp. This project will provide you step by step instructions to write scripts to automate API testing using Rest Sharp, how to automate and test CRUD (Create, Read, Update and Delete) operations with HTTP methods like GET, POST, PUT and DELETE, and adding assertions to the API response.
