It looks like a shortcut. It's usually a loan — with interest paid in production incidents, lost customers, and emergency weekends.
Most teams don't decide to skip testing. It just gets deprioritized — one release at a time — until "we'll test it properly next sprint" has quietly become the permanent policy. By the time it becomes a visible problem, it's usually an expensive one.
A bug caught during development costs a developer a few minutes. The same bug caught by a customer costs a support ticket, an emergency patch, a rushed deploy outside your normal review process, and — if it touches payments, data, or uptime — real damage to trust that took months to build. Untested code doesn't remove risk from a project; it just moves the risk downstream, to the worst possible moment: after launch, in front of real users.
A recurring bug is rarely a coincidence — it's usually a sign that a code path has no regression coverage, so every unrelated change has a chance of breaking it again.
If shipping a one-line fix makes your team nervous, that's not a people problem — it's a signal that nothing is verifying the parts of the system you're not directly touching.
What worked when three people manually clicked through the app before release stops working once you have real user volume, more integrations, and less room for a bad Tuesday.
Functional bugs and security vulnerabilities are usually found by the same discipline, just aimed at different questions. Software testing asks "does this work as intended?" Penetration testing asks "can this be made to do something it shouldn't?" Products that skip the first question almost always have gaps in the second one too — an untested input field is very often an unvalidated one.
It doesn't need to mean months of process overhead. In practice, it's usually: automated regression tests that run on every change, a manual pass on anything user-facing before release, and a security review on anything that touches auth, payments, or user data. That's enough to catch the vast majority of what would otherwise become an incident.
