Good Question, As nowdays testers are shifting from Manual to Automation testing.
The trend is changing among the testers worldwide which in result increasing the demand of test Automation tools in the market.
I am a Manual tester itself trying to Automate my testing for which i have been through a list of Automation tool that are available in the market, Some are paid, some are open source. Some are exceptionally good in performance but some are not even giving the desired results.
So there is kind of a confusion in the Testers about which tool should be used, to get better results.
The list of tools i have checked out are mentioned below and may this list will be helpfull to the Testers out there.
