Rest API Testing (Automation) from Scratch-Rest Assured Java (Udemy.com)

Top Ranked #1 Rest API Test Automation & postman tutorial with Java from Basics to Framework with Real time examples

4.6
49,126 reviews

Created by: Rahul Shetty Academy

Last updated April 2026

Our take

Based on the ratings of 49,126 students, a sample of their written reviews and the syllabus, as the course stood in April 2026. No course pays to be reviewed.

This is Rahul Shetty's REST API automation course, built for testers who have never written a line of automation code. It starts with Postman and REST basics, then moves into REST Assured with Java, working through real hosted APIs from Jira, Twitter, Google Maps, and YouTube instead of toy examples. By the end it covers POJO classes, OAuth 2.0, Cucumber BDD, TestNG, Maven, and a GraphQL section added in a 2026 update, so the stated goal is a working framework, not just isolated scripts.

Reviewers consistently praise how clearly Shetty breaks down concepts that sound simple but trip people up once they try coding them themselves, and one reviewer said the course helped her recall skills she'd used at a previous job. The recurring complaint is downloadable notes: a few reviewers want a PDF of the material instead of rewatching lectures to find a solution. One reviewer said the POJO class section is missing the sample API used on screen, which makes that part harder to follow along with. A single one-star review called the teaching disorganized and the audio quality poor, though that view is far from the norm in the sample.

At 4.6 stars across 49,126 ratings, with 27,338 five-star reviews against under 1,000 one- and two-star ratings, the overall reception is strong and consistent. The course was last refreshed in April 2026, so the GraphQL and OAuth material is current rather than stale. For a tester who wants one course covering Postman, REST Assured, and framework building without needing prior programming experience, this is a solid, well-reviewed pick.

Best forManual testers with no coding background who want a full API automation framework, not just theory
Skip it ifYou already automate REST APIs and just want a quick GraphQL or OAuth refresher

Pros

  • Uses real hosted APIs like Jira, Twitter, and Google Maps instead of toy examples
  • Goes all the way to a Cucumber BDD framework with Maven and TestNG
  • Assumes zero coding or automation background and builds up from scratch
  • Refreshed in April 2026 with new GraphQL testing content

Cons

  • No downloadable notes or PDF, several reviewers want a way to review concepts without rewatching lectures
  • One reviewer says a sample API used in the POJO class section isn't included in the resources
  • At 152 lectures over roughly 24.6 hours, it's a long commitment for a niche testing skill
The course is excellent, delivering knowledge in a very clear and structured way. The teaching style makes even complex topics easy to understand.

It good be better if provide that whole class pdf evrythig good only that is

By Shaila Chougule on 8/12/2026

Yes it was good but most of the things looks easy while listening but looks difficult while working on it actually. So it would be better if you provide some notes which covers all your topics and make it available for download. Otherwise each time we have to go to that particular lecture and check it how you have resolved it and we also not able to take notes of all the points.

By Chinmaye Chinnappa H E on 7/14/2026

The course is excellent, delivering knowledge in a very clear and structured way. The teaching style makes even complex topics easy to understand. Overall, it feels both engaging and highly effective for learning.

By Dipika Tambe on 5/23/2026

Very well explained in a properly structured format. I am new to the Rest Assured concept, but I was able to understand everything on the first attempt itself because Rahul Sir explained each and every topic in detail and with great depth, even the small concepts. His way of teaching makes even complex topics easy to understand.

By Kuldip Mishra on 4/24/2026

I personally learned lot by taking this course. The teaching flow of Rahul Sir is amazing. I am from non IT background but Rahul sir makes very easy to understand each topics taught by him. I really appreciate your hardwork. Keep of the good work!

By Karan Sagale on 4/15/2026

A comprehensive course to learn API testing with Rest Assured from scratch. Covers core concepts, validations, and framework design with practical examples. Easy to understand and well-paced for beginners. Some topics feel repetitive and advanced areas like CI/CD or real-world integrations could be expanded. Overall, a great starting point for API automation.

By Aravinth Kumar on 4/5/2026

Its an amazing experience to learn with rahul shetty academy online course, its more clear and easy to understand the concepts. Hope i will do implement the concepts with more confidence . Fingers crossed.

By Prateek jain on 3/28/2026

I would like to sincerely appreciate Rahul Shetty for his excellent Rest Assured API course. The way he explains concepts step by step makes even complex topics easy to understand. The hands-on examples and real-time scenarios really helped me gain confidence in API automation. Thank you for creating such a valuable course and making learning so engaging and practical. Highly recommended for anyone looking to strengthen their API testing skills!

By Nishita on 2/18/2026

This course has a detailed explanation for API testing based on real time projects. I do recommend this to anyone who is preparing for next automation testing interviews.Best of Luck!!!

By Mariia Kulgava on 2/16/2026

I'm giving this course a low rating because: 1. The instructor does not follow proper syntax or format the code consistently. The messy code is very difficult and frustrating to read. 2. The correct test structure is not introduced from the beginning; instead, the main() method is used throughout. 3. I am familiar with Java, but I decided to watch the Java section out of curiosity. Unfortunately, the explanations do not stand up to scrutiny. If someone is new to Java, these lessons are unlikely to provide a solid understanding.
