# AI Healer

Test healer is a powerful tool that can help you quickly assess and eliminate mistakes in your tests. When a test run fails, Healer analyzes Scenario and target web page, and tries to understand why the run failed and how to make it pass.

Consider the following basic example. Here we try to click on 'Get Started' button and verify that we've been redirected accordingly. The only issue is, there's been a minor typo - the letter 'd' in the selector is doubled.

As expected, the test fails and when we go to the test run report for details, here's what we see:

Not only does it correctly recognize that there are no matches for the mistyped selector and what the right one is, DogQ's Healer also proposes a fix that you can use if you see fit.
