To my understanding, all the testing follows a Testing 
Process. Test Process is something which we have to execute 
in step by step. We cannot skip any of the process defined 
for a bug free application. Following is the Test Process 
which are in terms of their priority:

1- Preparation of URS.
2- Preparation of Test Plan (Very important Step).
3- Preparation of Test Cases from URS.
4- Execution of the Test Cases.
5- Defect report and tracking.
6- Test Report Summary.
