The Self-Healer: Test Cases That Stay Valid No Matter What Changes

Test maintenance is the cost nobody budgeted for.

Mobile QA teams don't just write tests. They maintain them. Constantly.

A button label changes. A flow gets restructured. A marketing pop-up appears mid-session that wasn't there when the test was written. A banner gets added to a screen that the test expected to look a specific way. Any of these, none of which represent a bug in the product, will break a test that was perfectly valid yesterday.

Someone has to find the broken tests, figure out what changed, update the steps, and rerun. It's not complex work. It's just endless, recurring work. And because it's triggered by every release, it scales with your shipping velocity. The faster you move, the more maintenance accumulates.

"The hidden cost of test maintenance isn't in any sprint. It's in every sprint." — Asad Abrar, Founder & CEO, Drizz

The deeper problem: maintenance is invisible until it isn't. A team running fast accumulates a growing backlog of stale tests quietly in the background, tests that fail not because the product is broken, but because the scripts haven't kept up. By the time someone notices, the backlog is large enough to slow down testing significantly.

THE FEATURE

The Self-Healer: detect, adapt, continue.

The Self-Healer is Drizz's automatic test repair capability. When a test step fails because something unexpected has changed — in the UI, in the flow, or anywhere else in the session — the system doesn't stop. It detects the failure, reasons about what changed, adapts its action, and continues the test.

What it handles

Most test breakages fall into predictable categories. The Self-Healer is designed to handle all of them:

UI changes: a button moved, a label changed, a screen was redesigned. The system identifies the correct element in its new state and continues.
Flow changes: a step in the user journey was restructured or reordered. The system adapts its path through the app.
Unexpected overlays : a marketing pop-up, an interstitial, a new onboarding prompt, a banner that wasn't there when the test was written. The system recognises the interruption, handles it, and returns to the test flow.

This last category matters more than it might seem. In fast-moving consumer apps, marketing modules and promotional overlays are deployed constantly and often independently from product releases. A test can break not because engineering shipped anything, but because the growth team pushed a campaign. The Self-Healer treats these as the non-issues they are.

How it worked in practice

In the Instamart wheat search test on Swiggy, the execution trace shows the Self-Healer in action: the first attempt to add 'Aashirvaad Superior MP Atta' to the cart didn't result in the item being added. The system detected the failure, corrected its action, and succeeded on the retry, without stopping, without any human intervention, without the test being marked as failed.

Metric	Before	With Self-Healer
UI change	Manual script update required	✓Adapts automatically
Unexpected pop-up or overlay	Test fails, manual patch needed	✓Detected and stitched past mid-run
Maintenance per release	Recurring — accumulates over time	✓Near-zero
False failures from stale steps	Frequent	✓Eliminated

Early-stage — coverage is expanding across more complex, multi-step flows in the coming weeks.

WHY IT MATTERS

Coverage compounds instead of decaying.

The practical consequence of the Self-Healer isn't just saved time on individual fixes. It's what happens to your test suite over time.

Without it, coverage decays. Tests break, backlogs form, and the suite gets less reliable with every release until someone dedicates time to a maintenance sprint. Teams end up running fewer tests than they should because the overhead of keeping them alive is too high.

With it, coverage compounds. Every test you write today stays valid through tomorrow's release, and the one after that. The suite grows rather than erodes. The backlog never forms.

For teams shipping at pace, that's the difference between a test suite that actually reflects the product and one that's perpetually playing catch-up.

What changes for your team:

No manual script updates after deployments
No time wasted diagnosing "real bug or stale test"
No maintenance backlog forming quietly in the background
Tests written today stay valid through future releases

GETTING STARTED

The Self-Healer is live. Your existing tests work as-is.

The Self-Healer is active for all Drizz users. No configuration required, it runs automatically as part of every test execution. Your existing test cases get the benefit without any changes.

To see it handling real-world breakages on your own app, book a demo and we'll walk you through a live run.
