Self-healing test automation

A locator-healing engine that updates broken selectors at runtime — keeping regression suites green and CI/CD flowing through frequent UI change.

Outcome

70% less script-fixing time

Outcome

75%+ better CI/CD uptime

Outcome

Manual investigation eliminated

Overview

With the application under frequent change, the regression suite kept breaking: low UI-automation pass rates, broken CI/CD pipelines, effort-intensive script fixes, and a slide back toward manual testing — causing downtime and regression-suite delays.

The challenge

Low pass percentage in UI automation
Frequent CI/CD pipeline breakage
Effort-intensive automation-script fixes
Manual testing creeping back as the default approach

Our approach

Automated locator healing using an LCS (longest-common-subsequence) algorithm dynamically during test runs
Captured the DOM structure of each UI page for comparison and storage
Detected locator changes and automatically applied updated locators to keep tests running
Generated detailed reports on locator updates and made the engine compatible with existing frameworks

Results & business impact

70% reduction in script-fixing time
Over 75% improvement in CI/CD pipeline uptime
Dynamic adaptation to application changes with less manual effort
Eliminated manual investigation of broken locators
