Describe Identify by Anchor.

• A. The anchor must be unique, and the target is found relative to the anchor using shortest path or coordinate methods.
• B. The anchor is optional and used only for visualization.
• C. Anchors are deprecated in Tosca XScan.
• D. Anchor only works with image-based identification.

Answer: (A)

Identify by Anchor uses a reference element that is unique on the screen as a fixed point of reference. The actual target element is located relative to that anchor, either by following the shortest path in the UI structure or by applying a coordinate offset from the anchor. This makes element identification more robust when UI elements move or reflow, because you’re anchoring to something stable.

The anchor must be unique to prevent ambiguity—if there were multiple possible anchors, the identification could pick the wrong one. Once the anchor is established, the search for the target uses its position in relation to that anchor, not an absolute location. This approach is not limited to image-based methods and isn’t deprecated; it’s a general way to keep interactions reliable even when layouts change.
