How do I prevent untested code from shipping?

Build a process where shipping requires passing checks rather than relying on discipline. Make testing a required step before release, part of the process every change must pass, not something done only if there's time, since untested code ships mainly because verification is treated as optional and skipped under pressure. Automate tests so coverage runs every build automatically and doesn't depend on anyone remembering or finding time, so a category of untested-code bugs is caught regardless of deadline pressure. And gate shipping on verification, a build that hasn't passed your tests and regression checks doesn't go out, which makes shipping untested code structurally difficult rather than just discouraged. The principle is to make verification a required gate rather than an optional step, so untested code can't slip out simply because nobody got to testing it, and to back the gate with per-version field monitoring that catches anything still slipping through.

Why does untested code end up shipping?

Almost always because testing is treated as optional and gets skipped, usually under deadline or momentum pressure. When verification is a separate, discretionary step rather than a required part of shipping, it's the first thing dropped when time is short or a change seems small ('just ship it, it's a quick fix'), so code goes out unverified. It also happens when testing depends on human memory and discipline, someone has to remember to test, find the time, and do it thoroughly, all of which fail under pressure or oversight. And without a gate, nothing structurally stops an untested build from shipping. The fix addresses each: making testing a required step removes the option to skip it, automating tests removes the dependence on remembering, and gating shipping on verification makes it structurally hard to ship unverified code. Untested code shipping is rarely a deliberate choice and usually a process gap, so closing the gap with required, automated, gated verification prevents it far more reliably than asking people to be more disciplined.

Should I block releases that haven't passed tests?

Yes, gating releases on passing verification is the most reliable way to prevent untested code from shipping. Relying on discipline, asking everyone to remember to test and to choose not to ship if they didn't, fails predictably under deadline pressure, when skipping verification is tempting and a small change seems safe. A gate removes the choice: a build that hasn't passed your automated tests and required regression checks simply doesn't ship, so untested code can't go out regardless of pressure or oversight. This makes shipping untested code structurally difficult rather than merely discouraged, which is what actually changes behavior. The gate should be calibrated, fast enough not to bottleneck shipping (automated tests plus a short regression checklist, not exhaustive manual testing every time) so it's sustainable, but firm enough that it genuinely blocks unverified builds. Combined with per-version field monitoring to catch anything that still slips through, gating release on verification is how teams keep untested code from reaching players without depending on everyone being perfectly disciplined every time.

How to Prevent Untested Code From Shipping

Quick answer: Make testing a required step before release, automate tests so coverage doesn't depend on remembering, and gate shipping on verification. Untested code ships when testing is skippable.

Untested code shipping, changes going out that were never verified, is how avoidable bugs reach players. Preventing it is about making verification a required gate, not an optional step. Here's how to prevent untested code from shipping.

Make Testing a Required Step Before Release

Untested code ships when testing is optional and skipped under pressure, so make testing a required step before release, part of the process every change must pass, not something done if there's time. When verification is built into shipping rather than bolted on, untested code can't slip out because nobody got to it.

Bugnet catches in the field the bugs that untested code causes, showing the cost of skipping. Making testing a required step prevents untested code shipping by removing the option to skip it, since the most common reason untested code ships is simply that verification was treated as optional.

Automate Tests So Coverage Doesn't Depend on Remembering

Manual testing that depends on remembering gets skipped, so automate tests so coverage runs every build automatically. Automated tests on your core logic verify code without anyone having to remember or find time, so a category of untested-code bugs is caught every build regardless of pressure or oversight.

Bugnet tracks crashes per version, complementing automated tests by catching what they miss. Automating tests prevents untested code shipping by making verification automatic rather than dependent on human memory and discipline, which fail under deadline pressure.

Gate Shipping on Verification

The strongest prevention is a gate, code doesn't ship until it passes the required checks. So gate shipping on verification: a build that hasn't passed your tests and regression checks doesn't go out. Gating makes shipping untested code structurally difficult rather than just discouraged, which is what reliably prevents it.

Bugnet's per-version monitoring catches anything that still slips through after the gate. So prevent untested code from shipping by making testing required, automating tests, and gating shipping on verification, building a process where shipping requires passing checks rather than relying on discipline alone.

Make testing a required step before release, automate tests so coverage doesn't depend on remembering, and gate shipping on verification. Untested code ships when testing is skippable, so build a gated process.
