When Passing Tests Are Just a Performance: The Hidden Cost of Testing for the Wrong Audience
There's a version of software testing that looks fantastic in a weekly status report. Coverage percentages climbing. Test suites running clean. QA signing off before the deadline. Everyone's happy.
Except the user who just hit a broken checkout flow on a Tuesday afternoon. Or the enterprise customer who discovered a data import bug three weeks after it shipped. Or the mobile user who's been silently churning because your app crashes on a specific Android version nobody on your team actually owns.
This is the quiet dysfunction that's taken root in a lot of engineering organizations: testing that's optimized for visibility rather than reliability. Call it what it is — testing theater.
What Testing Theater Actually Looks Like
Testing theater isn't always obvious. It doesn't announce itself. It creeps in gradually, shaped by the incentives and pressures that accumulate inside growing teams.
It looks like a QA checklist that gets rubber-stamped on Fridays because the release is already scheduled. It looks like unit test coverage measured by line count rather than by which lines actually matter. It looks like end-to-end tests written to cover the happy path your product manager demoed last quarter — not the weird, unpredictable paths real users take.
One senior engineer at a mid-sized SaaS company put it bluntly in a conversation we had recently: "We knew which tests the VP looked at in the report. So those were the tests that always passed. The stuff that was actually hard to test? That lived in a backlog nobody touched."
That's not laziness. That's a rational response to misaligned incentives.
The Metric That Ate the Strategy
Here's what typically happens. An organization decides it needs better visibility into test quality, so it picks a metric — coverage percentage, test count, pass rate — and starts tracking it. Leadership celebrates when the number goes up. The number goes up by people writing tests that make the number go up.
This is Goodhart's Law in a dev environment: when a measure becomes a target, it ceases to be a good measure.
A 90% coverage rate sounds reassuring until you realize it includes 40% coverage of your authentication module and 95% coverage of a utility function that formats dates. The metric doesn't know the difference. Your users definitely do.
The same dynamic plays out with pass rates. A team under pressure to ship can — intentionally or not — structure tests around the code that works rather than the code that's risky. Tests that might fail get deprioritized. Tests that always pass get promoted. The suite stays green. The bugs stay hidden.
Why Engineers Play Along (Even When They Know Better)
It would be easy to frame this as an individual failure, but that framing misses the point entirely. Most engineers who end up contributing to testing theater are smart people caught in systems that reward the wrong behaviors.
Release pressure is real. When a sprint ends and a feature has to ship, the calculus shifts. Writing a thorough test for an edge case you might never hit in production feels like a luxury. Especially when nobody in the retro is going to ask "did we test the weird stuff?" — they're going to ask why the deployment took 20 minutes longer than last time.
Another engineer we spoke with described it this way: "I'd spend two hours writing a test that covered a real failure scenario we'd seen in staging. And then I'd spend 30 minutes writing three tests that covered things we'd never actually break just to hit our coverage target. The 30-minute tests are what showed up in the report."
When the feedback loop rewards the wrong output, smart people adapt to it. That's not a character flaw — that's just how incentive structures work.
The Shift from Defensive Testing to Useful Testing
Breaking out of the theater model requires rethinking what testing is actually for. And that starts with being honest about who the real audience is.
Tests aren't for your engineering manager. They're not for the QA dashboard. They're not even really for your CI pipeline. They're for your users — specifically, to catch the failures your users would encounter if you didn't catch them first.
Once you anchor to that, a few things follow naturally.
Start with failure modes, not features. Instead of writing tests that verify your code does what you built it to do, write tests that probe what could go wrong in the real world. What happens when the API times out? What happens when a user uploads a file that's twice the expected size? What happens when two users edit the same record at the same time?
Weight your tests by user impact, not code proximity. The most-tested code should be the code that, when it fails, causes the most damage — to users, to revenue, to trust. Not the code that's easiest to write assertions for.
Make edge cases first-class citizens. The weird paths users take aren't bugs in the user. They're signal. If your test suite only validates the happy path, you're not testing software — you're testing a demo.
Decouple test metrics from performance reviews. This one's harder organizationally, but it matters. If engineers are evaluated partly on test coverage numbers, they will optimize for test coverage numbers. Evaluate on outcomes instead: production incident rates, time-to-detect, mean time to recovery.
Building a Culture That Tests for Real
Organizational change is slow, and nobody's pretending this flips overnight. But there are low-friction places to start.
Post-mortems are one of the best. When a production incident happens, one of the standard questions should be: "Did we have a test that should have caught this? If not, why not?" That question, asked consistently, starts shifting where test effort goes.
Another lever is making user behavior data visible inside the testing conversation. Session recordings, support tickets, error logs from production — these are maps of where real failures live. If your test suite isn't covering the scenarios that show up in those sources, you have a gap worth naming.
Finally, give engineers explicit permission — and time — to test the risky stuff. Not the easy stuff. Not the stuff that makes the coverage graph look good. The stuff that, if it breaks, somebody's going to have a very bad day.
The Bottom Line
Testing theater exists because the incentives that create it are real. Deadlines are real. Reporting pressure is real. The desire to show progress in a standup is real.
But the cost of performing tests for your boss instead of your users is also real — it just shows up somewhere less visible. It shows up in support queues, in churn data, in the engineering time burned fighting fires that should have been caught earlier.
The goal of testing isn't to look like you're shipping quality software. It's to actually ship quality software. Those two things can diverge pretty dramatically when nobody's paying attention.
At TryChec, we think the best testing culture is one where engineers test because it makes their work better — not because it makes their metrics look better. The difference is worth chasing.
