Quick answer: Monitor per version after release so a new crash or spike is caught fast, test the areas a change affects, gate releases on stability, and verify fixes, a regression is something a change broke, caught by per-version comparison.
A regression, something that used to work now broken by a change, ships when you cannot catch it. Here are the best ways to catch regressions.
Monitor Per Version After Release
Catch regressions by monitoring crash rate per version after release with alerts, so a regression that slipped through (a new crash or crash-rate spike on the new build) is caught within minutes, before it spreads. This is the key safety net for what testing missed.
Bugnet tracks crash rate per version and alerts on spikes, so a regression surfaces within minutes of shipping (the new build's crashes), letting you roll back or fix before it spreads.
Test the Areas a Change Affects
Catch regressions by testing the areas a change affects, not just the change itself, since a change can break related functionality. Test the affected areas, especially on real devices, to catch regressions before they ship.
Bugnet complements testing by catching the regressions that slip through, capturing crashes per version so a regression testing missed surfaces fast from real players, with the context to fix it.
Gate Releases on Stability
Catch regressions before they go wide by gating releases on stability, compare a new build against the previous one and do not ship (or stage the rollout) if it is obviously worse. This catches a regression before it reaches everyone.
Bugnet tracks crash rate per version, so you can compare a new build against the last and gate or stage the rollout, catching an obviously-worse build before it ships to all players.
