There are lots of ways to make sure that a software is working properly and one of them is to make use of testing, either manual testing or Automated Software Test.  Some even make use of them both and they say that one cannot exist without the other.  They should complement each other and not be like rivals of each other. They both have pros and cons and they can help each other out with the cons.  

I have had experience with the manual testing and not with Automated testing.  And all I can say is that it did not work well at all.
