Software regression

Software regression is when something that used to work in a computer program or software application stops working. For example, a button that used to open a particular menu might no longer work after the software was changed or updated. To fix this problem, you need to do something called 'regression testing', where a specialist checks the software to make sure everything is working the way it should. This could involve changing settings, running tests, or even undoing changes made to the software to see if it fixes the problem.
