Which panel of the UI Explorer interface contains all the UI elements of an opened application?

The UI Hierarchy panel in the UI Explorer interface displays all the UI elements of an opened application in a structured format. This panel is crucial for automation development as it presents a clear and organized view of the application’s interface elements, allowing developers to easily locate and interact with the components they want to automate.

The UI Hierarchy typically shows the relationships between various UI elements, such as parent-child relationships, which can help developers understand how different parts of the interface interact. This is especially useful when trying to identify and control specific UI elements during automation tasks.

The other panels serve different purposes: UI Frameworks help in selecting the appropriate automation technology based on the application type, Edit Attributes allows developers to modify properties of the selected UI element, and Visual Tree provides a graphical representation of the UI components but does not list them in a hierarchical manner. Hence, the UI Hierarchy is the most relevant for seeing all UI elements at a glance.
