What is auto-healing in test automation?

Auto-healing in test automation is an AI-powered capability that automatically detects and fixes broken locators when a web application's UI changes, allowing tests to continue running without manual intervention.

How does the Auto Healing Agent detect broken locators?

During test execution, the Auto Healing Agent continuously monitors the DOM for changes. When a locator breaks, it compares the current page against a saved baseline and applies the closest matching replacement automatically.

How does auto-healing reduce test maintenance effort?

Auto-healing eliminates the need to manually update test scripts every time the UI changes. Broken locators are fixed at runtime, so your team spends less time debugging failures and more time building new coverage.

Does auto-healing work in CI/CD pipelines?

Yes. TestMu AI's Auto Healing Agent runs during automated test execution in CI/CD pipelines, recovering from locator failures before they break your build and keeping pipeline results stable across frequent releases.

What is Smart Heal and how is it different from Auto Healing?

Smart Heal is TestMu AI's auto-healing capability for real device automation. It uses AI/ML to detect and recover from locator failures on real iOS and Android devices, and surfaces AI-powered suggestions when it cannot fix an issue automatically.

Are there failures that auto-healing cannot fix?

Auto-healing works best with locator changes caused by UI updates. It cannot recover from WebDriver initialization errors, network failures, or complete page redesigns. All healing actions are logged so your team can review what was fixed and identify recurring issues.
