What is regression testing?
In short
Regression testing is the practice of re-running tests against existing behaviour after every change, to catch breakages in shipped functionality.
Short answer
Regression testing is the practice of re-running tests against existing behaviour after every change, to catch breakages in shipped functionality.
What this actually means in practice
It's the difference between fast, confident releases and slow, fearful ones. The suite must be automated, fast enough to run on every PR, trustworthy (low flake), and maintained alongside the code it tests.
The most common pitfall
A 5,000-test regression suite that nobody trusts because half of it is flaky and the other half is unread.
What to do next
Audit your regression suite for flake, coverage and trust — then prune ruthlessly.
