Automated testing tools have been used commonly for their ability to speed up testing processes, ensure consistent results, and save valuable time and effort. However, like any powerful tool, it comes with its own challenges. Flaky tests, unexpected failures, and the need for constant maintenance can hinder the full potential of [automation testing](https://www.lambdatest.com/automation-testing?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=webpage).

To deal with such issues, our team of driven developers has come up with the all-new Auto Healing feature to transform your [Selenium testing](https://www.lambdatest.com/selenium-automation?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=webpage) journey. It is a game-changing feature that automatically empowers your tests to recover from certain failures, making your test suite more robust and reliable.

So buckle up as we dive into the nitty-gritty of the Auto Healing feature, its reliability, and how it can effortlessly handle changes in web elements without breaking a sweat.

### Enhanced Robustness For Your Test Suite

Test flakiness and unexpected errors can be frustrating challenges in automation testing. With the Auto Healing feature enabled, these issues become a thing of the past. The feature proactively handles unexpected situations and errors, improving the overall reliability of your test suite.

To benefit from the Auto Healing feature, all you need to do is pass the “autoHeal: true” capability in your [WebDriver](https://www.lambdatest.com/learning-hub/webdriver?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=learning_hub) configuration. It’s that simple! Here’s an example of how to enable Auto Healing in your test setup:

**Note:** The given below code snippet is in JavaScript. However, you can use the below code in your preferred programming language.

```plaintext
const capability = {
    "browserName": "Chrome",
    "browserVersion": "114.0",
    "LT:Options": {
        "platformName": "Windows 10",
        "project": "Untitled",
        "username": "Your Username",
  "accessKey": "Your access key",
        "w3c": true,
        "plugin": "node_js-node_js",
        "autoHeal": true // Enable autoheal
    }
}
```

If you wish to learn more about the Auto-Healing feature, check out our [detailed support documentation](https://www.lambdatest.com/support/docs/auto-healing/?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=support_doc).

### Automatic Detection of New Locator

In web applications, elements can change their locators due to updates. But don’t worry! The Auto Healing feature is equipped to handle this seamlessly. It automatically detects new locators and continues test execution without any manual intervention. Here’s a simple test case to demonstrate the Auto Healing feature in action:

```plaintext
import { Builder, By } from 'selenium-webdriver';

describe('Amazon Search Box Test', function () {
    // Test setup code here...
    it('should change id of search box and find element', async function () {
        // Test steps here...
    });
});
```

### Addressing the Limitations

While the Auto Healing feature is a powerful addition to your testing arsenal, there are certain limitations to keep in mind:

1. **Non-recoverable Errors**: Auto Healing cannot recover from all types of errors, such as WebDriver initialization or system-level failures. However, it effectively handles a wide range of issues.
    
2. **Test Accuracy**: While Auto Healing reduces test flakiness, reviewing the logs and understanding why a test needs healing is essential. This ensures that any real issues are properly addressed.
    
3. **Performance Impact**: Enabling Auto Healing may impact test execution time due to additional checks and recovery mechanisms. However, the benefits far outweigh the minimal impact.
    

Additionally, the Auto-healing feature is currently supported on all browsers and the latest browser versions except IE.

Remember, while the Auto Healing feature is valuable, it does not replace good [test design](https://www.lambdatest.com/learning-hub/test-design-tool?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=learning_hub) and error-handling practices. Ensuring your tests are well-designed and have proper error handling in place is crucial.

With the Auto Healing feature, [Selenium](https://www.lambdatest.com/selenium?utm_source=devto&utm_medium=organic&utm_campaign=sept_27&utm_term=ap&utm_content=webpage) web automation becomes even more resilient and efficient, allowing you to focus on delivering high-quality applications with confidence.
