1.Top Down Approach(Studs) 2.Bottom Up Approach(Drivers) Unit Testing : This testing is done by the developers not by the testers.Unit Testing is completely based on internal coding. Approach : 1.Equlvalence Partioning 2.Boundary Value Analysis 3.Error Guessing Regression Testing : The main objective of regression testing is to check the new functionalities without disturbing the old functionalities. Generally Regression Testing is used for automation tools. What is the difference between retest and regression testing? Retesting: testing the same application to make sure that it does not create any defects and if it does create defects we r going to fix the bugs and then comes regression testing. in other words retesting is performed to ensure that if at all the bugs were found we r going to perform regression testing.this means that retesting and regression testing are performed in a cyclic process or chain process. Retesting: testing the application before enhancements or changes or fixing the bugs. Regression testing:testing the component/system/appl after fixing the bugs or after some changes or enhancements. ________________________________________ Testing is the process in which defects are identified,isolated,subject for retification and ensure that the product is defect free,in order to produce a quality productin the end and hence customer satisfaction. Retest is the process of testing the same functionality again and again with multiple sets of data in order to confirm whether the functionality is working fine or not and also to rule out any environmental issues.
