Regression Testing

Software is interconnected in ways that are not always obvious. A small fix in one area can have a ripple effect somewhere seemingly unrelated, a new feature can disturb an old one, and a dependency update can change behaviour you relied on. Without a safety net, every release becomes a gamble, you fix the bug you knew about and unknowingly ship two you did not, and customers become your regression testers in production.

Regression testing removes that gamble. By systematically re-checking existing functionality whenever the software changes, we catch the things that have quietly broken before they reach your users. As the product grows this becomes essential rather than optional: the more features you have, the more there is to accidentally break, and the more valuable it is to know, every release, that everything that worked yesterday still works today.

We build a regression suite that covers the features your business and your users depend on, and run it whenever the software changes, so a regression is caught within the same cycle it was introduced, while the cause is fresh and the fix is cheap. The alternative, finding it weeks later in production, is far more expensive in time, money and trust.

Where it makes sense we automate the regression tests so they run fast and consistently on every build, freeing skilled testers to focus on exploring new functionality rather than re-checking old ground by hand. We keep the suite maintained as the product evolves, because a regression suite that is left to rot quickly gets ignored, and an ignored safety net protects nothing.
