About This Course

Learn the testing of Restful web services using the Apache HttpClient Library from scratch and Rest Assured Framework

RESTful Web Services are REST architecture based web services. In REST Architecture everything is a resource. RESTful web services are light weight, highly scalable and maintainable and are very commonly used to create APIs for web based applications.

This course will teach you about the testing of Restful Web Services. In this course everything is taught from scratch.

In the first section, I am going to discuss about the basic of restful web services and required concept for this course.

In the next section, we will start with manual testing part of restful web services using Postman client. Which will give you more detail understanding about what we should test. This includes

Concept of HTTP methods (GET,POST,PUT and DELETE)
Creating and sending the request using Postman
Validation of response body and status code
Attaching the custom headers to the request
Validation of response in Json and Xml format

In the next section, I will start with the automation part, discussing about Apache HttpClient library. This includes

Setting up the Maven project for the automation
Creating and sending the HTTP request (GET,POST,PUT and DELETE) from the code
Attaching the custom headers to the request from code
Validation of response body and status from code
Deserialization of response in Json and Xml format
Handling the endpoint secure with SSL
Framework development

By the end of this course, you will have great understanding of restful service and how to automate them using Apache HttpClient library

The course is not limited to following content. In future I will keep adding the new topics to this course.

And source code shown as part of video lecture will be provided for download

By the end of this course you will give have great understanding of Restful Services
By the end of this course you will have great understanding of Postman client
By the end of this course you will have great understanding on how to use Apache HttpClient Library
