Answer:
Regression test
Explanation:
There are different types of testing in software development. Some of them are;
i. Smoke test
ii. Interface test
iii. Alpha test
iv. Beta/Acceptance test
v. Regression test
vi. System test
While all of these have their individual meanings and purposes, the regression test seeks to confirm that a recent update, modification or change in the underlying program code of the application (software) has not affected the existing features. This test ensures that a change to a software has not introduced new bugs or vulnerabilities to the state of the software before the change was made.
Regression test is actually done when;
i. there is a change in requirements of the software and thus the code is modified.
ii. a new feature is added to the software.
