Instead of us humans running a function over and over with different parameters and checking the results are what we expected them to be, we let the computer do this for us. Software testing can be divided into two classes, Mannual testing and Automated testing. Automation Testing or Test Automation is a software testing technique that performs using special automated testing software tools to execute a test case suite. Having written our test cases let us now test our application for any bugs.
