How often should regression run?

Ideally on every release and every pull request. Automated, it runs itself in your CI on each change, so you know within minutes if you've broken something, without depending on someone remembering to test it by hand.

Manual or automated regression?

We automate the stable, repetitive cases — most of a regression suite — because that's where automation pays off. What still changes a lot stays manual until it settles.

Do you have to re-test everything on every change?

Not always. We select the critical cases and the ones the change can affect via the traceability matrix; that keeps regression thorough where it matters without dragging on every release.

What happens when the app changes and the suite fails?

Continuous maintenance is included: we tell a real failure from a case that just needs updating, and adjust the suite so it stays reliable. A suite full of false failures gets ignored, and that makes it useless.

Regression tests

Every new change can break something that already worked. We re-run the tests for what was already fine on every version, so you ship features without fear of regressions.

01 / The service

What is regression testing?

Regression testing verifies that the features that already worked keep working after a change. Every time a feature is added, a bug is fixed or a dependency is updated, there's a risk of breaking something that was working. We call that a regression.

We re-run a set of cases, manual and automated, over what was already validated, comparing the current behavior with the expected one. This way, every version that ships keeps intact everything your users already took for granted.

02 / Why it matters

Why without regression there are no calm releases

The fear of breaking something is what slows deployments. Without a regression safety net, every change is a gamble and every release a sleepless night. With it you protect your software quality: your team ships fast and certain that what already worked stays green, version after version.

Frequently asked questions

It's when a change — a new feature, a bug fix, an updated dependency — breaks something that used to work. Regression testing re-runs what was already validated to catch those breakages before they reach the user.
