What Our Users Are Saying

The course is excellent the content is first class and I found Anton to be very interesting and knowledgeable. I would highly recommend the class to looking to learn automation or just as a refresher course.

Brad Winborg

For now, I used only the web version of the tool because of project specific. There is some stuff I really like Locators – At the begging, it was a little hard for me to use them, but later when you get used them a little more you realize that this way for creating of elements is better than normal WebDriver one. Contains methods for IDs and classes are AWESOME! Framework’s Extensibility is excellent. They provide all default HTML elements.
