Agentic AI QA: Beyond Scripted Testing

Introduction

For years, QA has been a bottleneck of brittle Selenium and Appium scripts that break the moment a developer changes a button ID. With Android 17 introducing new UI paradigms and stricter background behaviors, the old “record and replay” model is officially dead. If your engineering team is still relying on static scripts for regression testing, you are not just slow; you are flying blind on the most critical user journeys.

Plavno’s Take: What Most Teams Miss

At Plavno, we see a fundamental misunderstanding in how most teams approach AI in testing. They treat it as a wrapper around existing tools—essentially using an LLM to write Appium scripts for them. This misses the point. True Agentic QA isn’t about writing code; it’s about reasoning through a user interface like a human would, but at machine speed. The critical failure mode we observe is the “illusion of coverage.” Teams deploy agents that click through happy paths, declare victory, and miss the edge cases where the app actually crashes. The risk isn’t that the AI can’t test; it’s that it can test *convincingly* while missing subtle logic errors or race conditions that a human tester would catch intuitively.

What This Means in Real Systems

Integrating agentic AI into a quality engineering stack requires a shift from linear scripts to event‑driven architectures. In a traditional setup, a CI/CD trigger runs a script; if the script returns exit code 0, the build passes. In an agentic system, the “tester” is a stateful agent with access to vision models and a DOM tree analyzer. It needs a dedicated orchestration layer—often built on frameworks like LangChain or custom orchestration using Kubernetes—that manages the agent’s lifecycle, session state, and credential injection.

Architecturally, this means your testing environment must look more like a production environment. The agent requires access to real device clouds or high‑fidelity emulators, not just headless browser instances. It needs to handle asynchronous events—like waiting for a push notification or a background sync—without hard‑coded sleeps (which are the bane of reliable automation). We are seeing a move toward “self‑healing” test pipelines where the agent, upon encountering a changed UI element, consults a vector database of previous UI states to infer the correct action. However, this introduces new dependencies: your test infrastructure now needs low‑latency access to vector stores and LLM APIs. If your inference latency spikes, your test suite duration explodes, potentially blowing up your CI/CD budget or slowing down deployment velocity.

Why the Market Is Moving This Way

The shift toward agentic QA is driven by the explosion of device fragmentation and UI complexity. With Android 17, Google is tightening permissions and altering how apps handle background processes, meaning tests that passed on Android 16 might fail silently on 17. Maintaining a library of static scripts for every OS version, screen size, and foldable configuration is becoming mathematically impossible for lean teams. The industry is realizing that the cost of maintaining test automation scripts has exceeded the cost of manual testing in many organizations, creating a “automation debt” paradox.

Technologically, the maturity of multimodal models is the catalyst. We now have models capable of understanding pixel data and semantic structure simultaneously, allowing agents to “see” a button even if the underlying ID has been obfuscated or changed by a minification process. This allows for testing based on *intent* (“Click the Checkout button”) rather than implementation details (“Click #btn-checkout-primary”). As applications become more dynamic—with React Native, Flutter, and server‑driven UIs becoming standard—the DOM is no longer a reliable source of truth for automation. The market is moving to agentic AI because it is the only approach that can handle the fluidity of modern mobile development.

Business Value

The business case for agentic QA is rooted in velocity and risk mitigation. In typical enterprise pilots we observe, teams using autonomous agents can expand their regression coverage from 20% of user journeys to over 80% within a single quarter. This is not a marginal gain; it fundamentally changes the risk profile of a release. Consider a high‑volume e‑commerce app: a checkout bug that goes undetected for 24 hours can cost hundreds of thousands of dollars. Agentic agents, capable of exploring the application state space randomly (fuzzing) alongside structured tests, find these “black swan” defects far more effectively than human‑written scripts.

From a cost perspective, while there is an upfront investment in custom software to integrate these agents, the ROI appears quickly. A standard manual regression cycle might take a QA team of five engineers three days to prepare and execute. An agentic system can execute the same coverage in 4–8 hours, unattended. This frees up expensive engineering talent to focus on exploratory testing and UX refinement, rather than the drudgery of script maintenance. According to vendor benchmarks and early adopter data, maintenance overhead for test suites can drop by 40–60% because the agents adapt to minor UI changes automatically, eliminating the “flaky test” syndrome that plagues CI/CD pipelines.

Real-World Application

Fintech Onboarding: A neobank launching a new KYC (Know Your Customer) flow used agentic AI to test the document upload process across 50 different Android devices. The agents identified a specific camera permission failure occurring only on Samsung devices running the Android 17 Beta, a scenario the static scripts missed because they mocked the camera hardware. This prevented a critical blockage for new users at launch.

Retail Inventory Sync: A logistics company needed to verify that their handheld scanning app correctly synced data in poor network conditions. Scripted tests failed because they couldn’t reliably simulate network latency and app recovery. Agentic agents were programmed to intentionally toggle airplane mode and force‑kill the app, observing if the local SQLite database persisted correctly. This resulted in a 30% reduction in field‑reported sync errors.

Healthcare Telemedicine: A telehealth provider utilized agents to test video connectivity across various OS versions. The agents were tasked with initiating a call, rotating the camera, and muting the mic. They discovered that on specific low‑end tablets, the video stream froze when the notification drawer was pulled down—a defect that would have caused severe compliance issues regarding patient data privacy.

How We Approach This at Plavno

We do not treat agentic QA as a “set it and forget it” tool. At Plavno, we design these systems with a “Human‑in‑the‑Loop” (HITL) verification layer. When an agent encounters a failure or an ambiguous state, it captures a screenshot, a network log, and a DOM dump, then flags it for a human engineer rather than failing the build immediately. This creates a continuous feedback loop where the human verifies the bug, and the agent learns from this confirmation to refine its future testing logic.

Security is also paramount. Since these agents often need valid credentials to test authenticated flows, we implement Just‑in‑Time (JIT) credential vaulting. The agent never has persistent access to production user data; it requests short‑lived tokens for the duration of the test session. We also focus heavily on observability. We instrument the agents to emit traces not just of their actions, but of their *reasoning*. Why did the agent decide to click element A over element B? This logging is crucial for debugging the tests themselves. If an agent starts hallucinating—clicking invisible elements or entering gibberish into forms—the observability stack alerts us immediately so we can adjust the prompt engineering or the model temperature before the pipeline is compromised. This rigorous approach to AI automation ensures reliability.

Our platform also leverages AI agents that can explore applications autonomously, learn from failures, and continuously improve test coverage without manual script updates.

What to Do If You’re Evaluating This Now

• Define the Scope: Pick 3–5 critical flows (e.g., Login, Search, Purchase). Avoid complex edge cases like payment gateways initially; focus on UI navigation and state management.
• Choose Your Battles: Use agents for UI‑heavy, dynamic applications (React Native, Flutter). They are overkill for stable, backend API testing where standard REST/GraphQL contract testing is still cheaper and faster.
• Budget for Latency: Agentic testing is slower than script execution because of inference time. Plan for a 2–3x increase in individual test duration, offset by the ability to run tests in parallel across more devices.
• Monitor the “Why”: Ensure your chosen platform or custom solution exposes the agent’s chain of thought. If you only get a Pass/Fail result, you have gained nothing over a black‑box script.
• Guardrails are Non‑Negotiable: Implement strict “sandbox” environments. Ensure the agent cannot accidentally trigger production actions, like emailing all users or deleting a database, even if the UI allows it.

Conclusion

The release of Android 17 Beta support via agentic platforms is a clarion call for the industry. The era of brittle, maintenance‑heavy test scripts is ending. For CTOs and engineering leads, the question is no longer *if* you will adopt AI in QA, but *how* you will architect it to be reliable, secure, and cost‑effective. The teams that embrace this shift will move from fighting fires to preventing them, shipping high‑quality software with a velocity that their script‑dependent competitors cannot match. Agentic AI is not just a faster tester; it is a different kind of engineer—one that doesn't sleep, doesn't get bored, and constantly learns from your evolving codebase.
