I started off as a manual tester before I decided to subscribe to automation. I assume that you already know the benefits of automation. To learn, you can take up physical classes or seek help from those that are used to automation before getting started. In addition to that, we are in a global village, the required knowledge as regards automation can be learned on websites or perhaps youtube. The most important thing is that individuals having an interest in automation must be ready to commit to learning. In my years of experience, I’ve encountered several persons that have learned automation online.
Peradventure you are worried about the validity of the information, no worries, you can always check reviews and comments as regards such online lessons. And it should be noted that to learn automation strongly depends on the aspect of automation you wish to engage yourself in.
