Locator failures are a meaningful problem for automation tests. A small UI change such as a renamed button and also an updated attribute or a new element hierarchy can cause brittle scripts to break so it leads to wasted debugging hours plus flaky builds and even slower release cycles.
TestMu AI introduces Smart Heal to solve this for Automation Tests on Real Devices. AI/ML algorithms give power to this new feature. Smart Heal automatically detects, analyzes as well as recovers from locator failures during runtime, ensuring your automation scripts stay quite resilient, even when the UI changes.
Before Smart Heal, locator failures were a recurring problem for QA and Dev teams:
Smart Heal requires at least one successful test run as a baseline. During this run, all element locators are captured and stored. This baseline acts as the foundation for future healing attempts.
Tip: Ensure your project and test names remain consistent across runs for baseline application.
After every successful run, Smart Heal updates the baseline with the most recent fully passed build, keeping it aligned with the latest UI state.
If an element is missing in subsequent runs, Smart Heal leverages AI to analyze attributes, DOM hierarchy, and visual cues to find the closest valid match.
Once a match is found, the step retries automatically with the healed locator, allowing the test flow to continue seamlessly. Both original and healed locators are logged for transparency.
If Smart Heal cannot confidently heal, AI-driven suggestions are recorded in the dashboard to help you strengthen your locators.
