Why Mobile Test Automation Keeps Breaking

Traditional mobile test automation breaks because it depends on selectors, fragile scripts, and implementation details that change with every UI, SDK, OS, and device update. Page Object Models, retries, and self-healing locators reduce some maintenance but don't solve the underlying problem. Drizz takes a different approach with Vision AI, reading real app screens like a human tester instead of relying on selectors. The result is faster test authoring, less flakiness, and significantly less test maintenance.

Are Vision-Based Tests Slower Than Selector-Based Tests?

Per step, yes, seconds vs milliseconds, and we publish our numbers. Per suite, the math flips: waits, retries, and triage decide real speed. Benchmark data inside.

Asad Abrar

Can AI-Written Tests Be Version Controlled and Reviewed?

Yes, if tests exist as human-readable steps that diff cleanly. Who wrote a change matters less than whether you can see it. The vendor test: "show me the diff."
