How can you improve the stability of UI element recognition in Tosca?

• A. Ignore the attributes and rely on the position.
• B. Use robust Attributes, multiple identification properties, and avoid brittle selectors.
• C. Only use a single, simplest locator.
• D. Disable UI recognition and use manual testing.

Answer: (B)

Stability in Tosca comes from identifying UI elements with robust attributes and multiple properties, not from vague or position-based hints. Relying on where an element sits on the screen is fragile because layouts change with screen size, resolution, or UI updates. By defining several identification properties—such as a stable automation or accessibility ID, control type, name/Text, and possibly class—and combining them, you create a unique, resilient signature for the element. If one property shifts, the others still anchor the recognition, so automation keeps working across UI changes. Using more than one property (AND) reduces the chance of accidentally matching the wrong element as the UI evolves. It’s also wise to avoid dynamic values and, when needed, use partial matches (contains/starts-with) only where appropriate, to balance stability and accuracy. Don’t fall back to a single locator or to relying on exact screen position, and don’t disable UI recognition—that would defeat automation and increase brittleness.
