I am not happy with the presentation and explanation. There are so many drawbacks here, 1) He is not even able to explain the process properly. And keeps on repeating this is not needed. this is not needed. 2) The way things are presented are nt clear.

Yes. Best part is i got to know errors which we may encounter while automating. For example Printing a response object in console. We should use S.O.P(respObject.asString()). It helps beginners and then always emphasizing on like POST/PUT should have ContentType.JSON It helps a lot @Vaibhav thank you :)

I really recommend this course to learn the basics of Rest, like post, put, get and delete, i also learned how to validate the response, and how to work with json file, i think that the fact that this is a free course makes it more incredible.
