Why learn Rest Assured and REST API automation?

REST Assured API is one of the most popular library when it comes to automating the REST APIs. Most of thetoday’s web applications are backed by the Micro services architecture and the REST APIs. Make no mistake, REST is gaining a lot of popularity amongst the developer community.

As a QA engineer, it becomes very important to test the REST APIs as a working API is crucial for a product. With great adoption ofOAuth 2.0 and Open ID Connect authentication mechanisms, it also becomes important to build an in-depth understanding of these authentication mechanisms. To speed up product delivery, the industry is gradually moving towards end to end continuous integration (CI) and continuous development process (CD). So it becomes critical that the backend API services are automated to facilitate and speed up this process.

This is wherethe role of a QA engineer becomes of utmost importance to be able to automate the backend API services. This is why you would want to learn everything about the REST Assured library to confidently automate the REST APIs and lead the effort single handedly. And, you have come to the right place!

Why this is the right course for you?

This REST Assured course is a one stop solution for all your API automation needs. This course will take you from the beginner level, all the way to be able to design and implement industry standard production ready API automation framework. By the end of the course, you will be confident enough to call yourself as an expert in the REST API automation space.

• This is probably the only course thatcoversserialization and de-serialization in great detail and that too withcomplex POJOexamples.

• This is the only course thatexplains many of the authentication and authorization schemes in REST API, in a simple manner and with live examples.For OAuth2.0, we have covered two famous APIs – Google and Spotify.

• This is the only course that values your precious time.Lectures are short, crisp and to the point. I have spent a great amount of time editing the videos so that you don’t have to waste your time just to learn a simple concept.

• This coursecovers many topics you will not find in other courses, for e.g. Lombok, Jackson Databind API, JSON Assert, Hamcrest assertions, etc.

• Before we start learning REST Assured and many of its cool features, I’ll spend a great amount of time toexplain you about the API basics, the HTTP concepts, what is REST, the HTTP methods, POSTMAN, Mocking APIs, JSON and JSON Path and also the basics of Java Programming language. These are the essentials one must become familiar with before jumping on with the REST Assured automation.

• I’ll explain you each and every REST Assured conceptwith live coding and I’ll not just write the code. I’ll also explain you what happens behind the scenes. This is the best way to learn something new. “Why” and “How” are more important than “What”!

• You will learnhow to think like an automation lead, plan and design the automation framework, optimizing the code, write clean tests and follow good programming practices. For e.g. you will always see me formatting the code (I hate poorly formatted code). It’s a small thing, but is very important!

• I’mVERY RESPONSIVE in the Q&A section. I respond to queries within 24 hours. If the time zone difference is not that huge, I can respond within 3-12 hours.

So, “Rest Assured”, by the end of this course, you will become an expert!
