Hope you are doing good.
I am working as a system admin on Linux operating systems since 10 years.
I want to switch to software or hardware testing , or basically testing is what I want to do.
What knowledge I need to acquire before I make a move. Does it need any testing certification. How much the certification would help me in my career switch. Please provide with info which would help me get a good idea of the field.
Thanks & Regards,
