Why We Need Regression Testing

Regression testing is a testing system that's done in order to confirm a code change in the program doesn't affect the present operation of the goods.  This testing makes certain the item works well as formerly with the recently added performance or some other alteration from the current attribute or after the bug repair is finished.  Formerly executed test instances are re-executed so as to verify the Effect of change.

When can we do Regression Testing?  We do applications regression testing if the manufacturing code has been modified.

To Plan a Successful Regression Testing One Must Determine First:

• To Plan, a Successful Regression Testing One Must Determine First
• what test-cases have to be implemented
• what needs to be improved and altered from the test-cases
• if it's essential to perform regression testing of this machine
• what and how must be automatic
• What's required to carry out the automatic testing
• The best way to test the results of this regression testing.
