Powered by AI, machine learning, and computer vision, CoTester by TestGrid dynamically adapts test scripts to UI and structural application changes in real time, reducing QA maintenance overhead and accelerating software release cycles.

ALPHARETTA, GA — November 4, 2026 —  [KOREWIRE] — TestGrid today highlighted the enterprise capabilities of AgentRx, the proprietary AI-powered self-healing engine built into CoTester, TestGrid’s enterprise-grade AI software testing agent. Designed to eliminate the bottleneck of brittle automated test scripts, CoTester by TestGrid enables quality assurance (QA) and engineering teams to automatically detect, adapt to, and heal broken locators and test logic during live execution.

As development and testing teams increasingly rely on test automation to accelerate software delivery, maintaining traditional automated test scripts remains a significant operational challenge. Conventional automation frameworks depend on rigid, single-attribute locators—such as ID, name, XPath, or CSS selectors—that are highly sensitive to application updates. Even minor user interface (UI) modifications, such as renaming a button or shifting page elements, can trigger widespread script failures and errors like NoSuchElementException. Consequently, QA teams often spend dozens of hours every week repairing broken scripts rather than testing critical application workflows and new features.

CoTester by TestGrid addresses this challenge directly through self-healing test automation—also known as auto-heal testing—which keeps test suites continuously synchronized with the latest version of an application without manual intervention.

“Modern software release cycles move too quickly for engineering teams to spend valuable cycles manually fixing brittle locators after every UI update,” said Harry Rao, Founder and CEO of TestGrid. “With CoTester and our built-in AgentRx self-healing engine, we engineered an enterprise AI testing agent that understands how applications evolve. By dynamically re-mapping elements and updating test logic in real time, CoTester by TestGrid gives QA teams the resilience they need to minimize maintenance costs, improve test coverage, and accelerate delivery speeds.”

How CoTester’s AgentRx Self-Healing Engine Works

Unlike traditional automation tools that rely on a single static identifier, CoTester’s AgentRx engine executes a continuous, four-stage self-healing workflow:

  1. Multi-Attribute Element Identification: AgentRx gathers multiple element attributes—including name, ID, CSS selector, text label, class, XPath, and relative positioning—to build a comprehensive profile of every interactive element.

  2. Structured Test Execution: During execution, CoTester follows predefined test steps to verify application functionality across specified user scenarios.

  3. Dynamic Real-Time Healing: If an element cannot be located via its primary identifier due to an application change, AgentRx does not immediately flag a false failure. Instead, the engine dynamically evaluates secondary attributes and re-maps the test during execution—adapting not only to renamed buttons, but also to structural shifts and complete UI redesigns.

  4. Validation and Continuous Learning: Once a test step is healed, AgentRx validates that the scenario executes as intended and updates the script for future runs. If an issue requires human oversight, the system flags it for manual review. Every update trains the engine to better predict and adapt to future application changes.

Core Technologies Powering CoTester by TestGrid

TestGrid developed CoTester’s AgentRx engine by combining three core artificial intelligence disciplines to scale reliably across complex enterprise environments:

  • AI and Machine Learning (ML) Algorithms: Deep neural networks process multiple data streams simultaneously—including Document Object Model (DOM) structures, visual cues, historical execution logs, and behavioral patterns—to make highly accurate healing decisions.

  • Computer Vision: Rather than depending solely on fragile HTML selectors, computer vision enables CoTester to recognize on-screen elements by their visual appearance, shape, color, and functional purpose, mirroring how human testers interact with forms and buttons.

  • Pattern Recognition and Predictive Adaptation: By analyzing thousands of test executions, AgentRx identifies how applications evolve over time, enabling predictive healing that anticipates structural updates before they disrupt release pipelines.

Enterprise Use Cases and Key Operational Benefits

By deploying CoTester and its AgentRx engine, enterprise QA teams experience fewer false test failures, reduced object flakiness, broader test coverage across edge cases and user flows, lower maintenance overhead, and faster feedback loops for developers. Key operational scenarios where CoTester by TestGrid delivers immediate impact include:

  • Dynamic Wait Mechanisms: Instead of relying on fixed wait times that cause premature interaction failures or slow down execution, CoTester dynamically adjusts waiting periods based on real-time element readiness and visibility.

  • Self-Healing API Testing: When API response structures or schemas change while core data remains intact, self-healing capabilities automatically adjust verification logic and request structures to prevent unnecessary test failures.

  • Visual AI Element Recognition: When web or mobile forms undergo underlying code refactoring, CoTester identifies interactive components visually, ensuring uninterrupted test execution.
