Course Description

REST Assured API is one of the most popular library when it comes to automating the REST APIs. Most of the today's web applications are backed by the Micro services architecture and the REST APIs.

REST stands for REpresentational State Transfer. REST is web standards based architecture and uses HTTP Protocol for data communication.

In REST architecture, a REST Server simply provides access to resources and REST client accesses and presents the resources.

no communication. no links or support. some complex sessions was not explained enough. no material to support - download,links,etc.

This course is full of information. Trainer has covered all the prerequisites as well. It is not only about RestAssured but a complete introduction to API testing methodology and Tools.

By Saumya ranjan Panigrahy on 11/13/2018

Good but it could be better if he shows the e.g of the web application and differentiates in the e.g why the web-service is batter then the web application

El instructor es super claro y estructurado, me ha encantado su forma de transmitir conocimiento, además de la buena estructuración que ha hecho de los tema. Buenisímo!

Tutor explains the areas in clear and concise manner. My only issue for the half mark is for the URLs in the Postman tutorials need to be updated.

Earlier i don't have knowledge of Rest Assured Now i am at decent position after watching these videos Thanks to Udemy for providing me such type of platform Thanks to the trainer- covered the things step by step with real examples.Now Rest Assured looks easy to me.

Good to watch and study.indepth xplainations and good xamples are available and is useful forboth a beginner and an xperienced one

It seems that some lessons were missing between two lessons (TestNG module). The example suddenly shows commands that weren't explained before.

By David Mateo Carmona on 5/11/2017

The course well explained and you will get an idea about how to use RestAssured. But it is very basic. Also the code is not well structured for a larger project. Also in one of the last chapters, the one talking about TestNG reporting, the author starts working with a selenium project never mentioned before on the course, so you can't follow completely all the lessons. Nethertheless it was worth the price, because you obtain a pretty good idea of RestAssured testing framework.

By Jayzwin on 3/1/2017

In the beginning of the course it was mentioned that an End to End project on JIRA will be done for demo but it was not done. This is a very basic course on rest assured. I am editing the above review here: It is a quick turn around from the instructor adding more videos here. Really appreciate that. I started automating our rest APIs in parallel to this video but was stuck because ours is form based login. It took a while for me to get that done. So if the instructor can add more flavors in the demo projects and more advanced concepts of rest assured would be great. We can really afford even more than this price if it is an advanced course instead of basics. I would highly recommend this for any beginner.
