# Element Repository

Use this section to learn tips and tricks for working with the Element Repository. These help you to create, manage, reuse, and update elements to support stable and maintainable test automation.

* **Scenario**: Test steps fail when the application User Interface (UI) elements have attributes that change frequently.\ <i class="fa-lightbulb-on" style="color:yellow;">:lightbulb-on:</i> **Tip & Trick**: Open element **Details** and enable the **Self-Healing** feature along with **Custom** attributes. This allows **Avo Assure** to identify elements even when some attributes change, which improves the stability of your tests.
* **Scenario**: When default element attributes are not enough to uniquely identify an element.

  <i class="fa-lightbulb-on" style="color:yellow;">:lightbulb-on:</i>**Tip & Trick**: Use [Custom Properties](/avo-assure/working-with-the-avo-assure-platform/create-and-execute-tests-with-design-studio/working-with-element-repository-section/custom-property.md) to define additional attributes for element identification.\
  This helps create more reliable element identification when standard attributes do not provide enough uniqueness.
