What our students are saying?

“I appreciate the time the instructor put on this course as well as the opportunity to get familiar with TestProject free of charge. Well explained, however, if you are using Windows and you are new in Automation Testing, you might find it a bit challenging with adding the SDK Token in your system environment since the instruction used MAC which is completely a different way with windows. Other than that… I appreciate a lot this free course …. thank you so much”

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
