Regression testing
Re-testing existing features after a change to make sure they still work
What's it for?
Checks that existing features still work after software has been changed.
For example…
After a checkout redesign, tests confirm old features still work.
After developers change the checkout, regression testing reruns login, basket, payment and refund checks to make sure unrelated behaviour still works.
Think of it like…
Walking the same safety route after a building renovation to be sure fire exits still open
