What is Automation Testing? 

Automation Testing in simple terms means the process of ensuring the functionality of a software through Automation before releasing it for public. This helps ensure that  the software does what it's supposed to do and doesn't have any problems when it's put out for people to use. 

Automated Testing involves using special Tools to run scripts that check how a program works. These Tools look at the software, tell you what happened, and check if it's working as it should. The cool thing is, you can make one script and use it many times.
