What student’s have to say about Trainer :
| The instructor “Rahul” is very knowledgeable and has knowledge on every latest tool required for automation. We had a interactive classes and it helped me in gaining knowledge and skills required for automation testing. Thank you Isha training for this – Reshav Das
The API Testing with Java: Rest Assured, Postman & Advanced Concepts course gave me practical experience with API automation using Postman and Rest Assured. A key takeaway for me was learning about the Rest Assured API automation framework and Newman reporting. Raghul’s clear explanations and guidance, along with real-world examples, made it easy to grasp concepts and confidently apply them in a professional setting. – Sandhya Rahul has immense knowledge on Automation, people who wants to get into automation just listen to Rahul demo classes and check his way of teaching and Isha training is good they are providing good trainers like Rahul with affordable fee. – Praween Reddy This course has been very helpful, each topic was covered in depth. Rahul sir had been very patient and took time to explain each and every question. – Madhu Mundhra Rahul is the best instructor and have a plenty knowledge of all the Automation concepts… initially I thought it was Rahul Shetty 😊 as his accent was same like him…he was very cooperative and always willing to help in person as well… – Babita Lugani I had a great time doing this course and it is great learning experience.Rahul was very helpful and responsive in clearing all our doubts.I would like to thank for the guidance provided by my tutor. Great and supportive environment to learn .- Monika Kanthi That was a great pleasure to learn from isha training solutions. Rahul sir was just amazing and he used teach in a way that everyone should understand each and every concept with an ease. Thank you for everything. – C. Harivardhan Reddy The course is very well explained and organized. I am personally very satisfied with what I have learned so far. – Bhanu Kiran Excellent course, thank you very much! In particular, I liked the way you approach the different topics step by step and guide students through these different steps. I also liked the challenges that force you to think through a problem. Furthermore, I also liked some of the videos, where you intentionally inserted errors that made code to fail. Overall, I thoroughly enjoyed this course! –Lei Yuvi |
