Don’t just take my word for it, check out what existing students have to say about my other courses:

“Great course! This was one of the most thorough training courses I have ever taken/endured/survived. For me, the course had a real “graduate course” feel to it, along with some almost impossible challenges that will result in frustration as well as some very deep learning.”- David Kotschessa

“The C# section is taught by someone else, which surprised me, but I think they did a great job at instructing at a beginner level. The Selenium materials are quite comprehensive and the instructor is easy to follow and understand. I am impressed that the author has taken the time to keep the course materials updated, and therefore merits 5 stars in my book!” – David Draper

“Well, I can’t explain in words how much am excited after completing this course. The more I was close to completion the more am getting excited. You are a great instructor Nikolay. You don’t just teach Selenium but other aspects of being a beautiful coder. Now am pretty confident and can say “Yes” to my clients when they need me to automate the application. Thank you Sir for all the hard work and effort you put into the course. Surely would like to see you in another engaging course!” – Randhawa Verma

I like the fundamental approach used by the author. Will see:) To prepare for such a course – it’s a really hard and big job. Respect and thank you.” – Serhii Kovalenko

Wonderful content and things explained in a nutshell. Overwhelmed by Author’s dedication to putting things in such a way that any novice or manual tester can follow and understand and definitely be on-boarded as a Selenium Automation Engineer the next day at work. Thanks a million, times for creating these courses! One Stop for Automation.”- Rupashree Geethaaviji Ananthakrishna

“I am familiar with Nikolay from a course I saw on TestAutomation and have the highest regard for him. Glad to see him on Udemy.” – Annamalai Viswanathan

“One Of the Best courses on Selenium With C#. Cheers Nikolay!!” – Saransh Vaid
