How do I do regression testing for my game?

Combine a checklist, automation, and per-version monitoring. Keep a checklist of the core flows that must always work, the game boots, saves load, the core loop completes, purchases work, and run it before every release to catch catastrophic regressions in minutes. Automate what you can so regression checks on core logic run every build without manual effort and don't get skipped under deadline pressure. Track crashes per version as a safety net so any regression that slips past testing surfaces fast as a spike on the new build. And test the areas your change could ripple into, not just what you changed, since regressions hide in code you didn't mean to touch.

Why do regressions happen in code I didn't change?

Because changes ripple through shared dependencies. A fix or feature in one system often touches code, data, or state that other systems rely on, so a function you modified for one purpose quietly breaks a feature elsewhere that called it, or a change in shared state invalidates an assumption another system made. This is exactly why regression testing covers core flows broadly rather than just the area you edited, and why testing the ripple areas a change could affect matters. It's also why per-version crash tracking is valuable: when a regression does slip through into untouched-seeming code, it spikes on the new build so you catch it quickly.

How can a small team keep up with regression testing?

Make it cheap and partly automatic so it actually happens. A short manual checklist of must-work core flows takes only minutes per release and catches the blunt game-breaking regressions that cause the worst fires, that alone is high return for low effort. Automating tests on your most critical logic provides a regression safety net that runs every build without anyone remembering to, which is far more reliable than ad-hoc manual testing under deadline pressure. And tracking crashes per version catches whatever slips through, since a regression that escapes both checklist and automation shows up as a crash spike on the new build. The combination gives small-team regression coverage without a QA department.

Tips for Regression Testing

Quick answer: Keep a checklist of must-work core flows and run it every release, automate what you can, track crashes per version to catch slips, and test where your change could ripple. Regressions hide in untouched code.

Regression testing, making sure new changes don't break things that used to work, is one of the most valuable and most skipped QA practices, especially for small teams. Here are practical tips for regression testing.

Keep a Checklist of Core Flows That Must Always Work

The foundation of regression testing is a checklist of the core flows that must always work, the game boots, saves load, the core loop completes, purchases work. Run it before every release. This catches the catastrophic regressions, the ones that turn an update into a disaster, in a few minutes.

A consistent core-flow checklist is the cheapest, highest-return regression practice for a small team. It won't catch every subtle regression, but it reliably catches the blunt, game-breaking ones that cause the worst launch-day fires, which is exactly what you most need to prevent.

Automate What You Can So Regressions Are Caught Cheaply

Manual regression testing every release gets tedious and skipped, so automate what you can, automated tests for core logic catch regressions without manual effort every time you build. The upfront cost pays off as the same checks run automatically forever, catching regressions you'd otherwise miss.

Automation makes regression testing sustainable rather than a chore you skip under deadline pressure. Even a modest suite of automated tests on your most critical logic provides a regression safety net that runs every build, which is far more reliable than remembering to test manually.

Track Crashes Per Version to Catch What Slips Through

No regression testing catches everything, so track crashes per version as a safety net, if a regression slips past your testing, the new build's crash rate spikes and you catch it fast. And test the areas your change could ripple into, since regressions hide in code you didn't mean to touch.

Bugnet tracks crashes per version, so a regression that escapes testing surfaces immediately as a spike on the new build. So do regression testing with a core-flow checklist, automation, per-version crash tracking, and testing the ripple areas, catching regressions before and after release.

Keep a checklist of must-work core flows and run it every release, automate what you can, track crashes per version to catch slips, and test the ripple areas. Regressions hide in code you didn't mean to touch.
