The Maintenance stage was created to re-test the application if it encountered any errors that required the programmers to rewrite various segments of code. There are two aspects that are necessary to test to ensure the fluidity of the application has been maintained.

First, check that the required changes have been implemented properly by the programmers. Second, while making the necessary changes to the software that the desired corrections did not cause inadvertent changes. Regression Testing is the procedure of testing the product against all previous test to determine the functionality of the remainder of the application has not been compromised. If the regression testing has been approved, we will package your software and ship it to the desited destination of your choice previously specified.
