fix it
Every change makes a quiet bet: that fixing or adding one thing did not break something that already worked. Regression testing is how you collect on that bet before your users do. You rarely have time to re-test everything, so the real skill is choosing what to re-check.
How a QA brain runs the check
What did this change touch directly, and what is built on top of it?
Which shared components could it have disturbed indirectly?
Are the critical flows — login, checkout, saving data — still solid?
Does this area have a history of breaking that warrants extra attention?
When a bug slips through, did I add a test so it cannot return quietly?
Why it matters
A neglected regression suite rots — full of tests for features that no longer exist and blind to the paths that matter. A tended one turns every release from a leap of faith into a routine step. The goal is not to test everything; it is to never be surprised by the same break twice.
