Understanding and Implementing Rest Assured using workflows and MindMap

Understanding Rest API

A REST API (Representational State Transfer Application Programming Interface) is a set of rules and conventions for building and interacting with web services.

Below diagram show the principles/workflow and response status code for Rest API.


Key Components of Rest API


1. Endpoint: This is the URL where the API can be accessed. Each endpoint corresponds to a specific resource or collection of resources.

2. HTTP Methods: These define the action to be performed on the resource. These are also known as CRUD (create, request, update and delete) operations

- GET: Retrieve data from the server.

- POST: Send data to the server to create a new resource.

- PUT: Update an existing resource with new data.

- DELETE: Remove a resource from the server.

3. Headers: These provide additional information with the request or response. Common headers include Content-Type (indicating the media type of the resource) and Authorization (containing credentials to authenticate a user).

4. Parameters: These are used to modify the request. They can be included in the URL (query parameters) or in the request body.

5. Request Body: This contains the data sent to the server when making POST or PUT requests. It's typically formatted in JSON or XML.

6. Response Codes: status of the request.

Understanding Rest Assured


REST Assured is an open-source Java-based library designed for testing and validating RESTful web services. It integrates well with testing frameworks like TestNG and JUnit. Below are key things, we will discuss in the article to keep it short and refresher only.
