# Understand Object Recognition Mechanism & Self Healing

Self-healing of objects refers to the ability to automatically recover from errors or unexpected conditions related to object identification or interaction. This feature enhances the robustness and reliability of automation scripts, especially in dynamic environments where objects may change frequently.

In this section you'll learn about various challenges faced in automation and how SimplifyQA works with self-healing of objects.

#### Common Challenges in Object Identification

* **Dynamic Object Attributes:** Elements on a web page may have dynamic attributes that change over time, making it difficult for automation scripts to identify them reliably.
* **Object Overlays:** Objects may be partially or completely obscured by other elements on the page, interfering with their identification.
* **Page Loading Delays:** Automation scripts may encounter delays in page loading, leading to synchronization issues and object identification failures.

#### Object Recognition & Self-Healing Techniques

1. **Object Attribute Flexibility:**
   * **Multiple Attributes:** Multiple attributes (e.g., ID, class, XPath) would be captured to identify objects, increasing the likelihood of successful identification.
2. **Object Synchronisation:**
   * Test scripts waits to ensure that elements are present or visible before attempting to interact with them.
3. **Object Recovery:**
   * **Alternative Paths:** After trying all above techniques, if it failed to recognise the object, then it updates the properties to up-to-date object available on screen.

#### Benefits of Self-Healing Objects

* **Increased Reliability:** Self-healing objects help prevent automation scripts from failing due to unexpected changes in the application under test.
* **Reduced Maintenance:** By automatically handling object identification challenges, self-healing can reduce the time and effort required to maintain automation scripts.
* **Improved Efficiency:** Self-healing can help automation scripts run more smoothly, reducing the likelihood of manual intervention and improving overall efficiency.
* **Enhanced Robustness:** Self-healing objects make automation scripts more resilient to changes in the application's user interface.
