What is a Dynamic ID in Tosca?

• A. Dynamic ID is a value of a property on a Module Attribute that can change during each run.
• B. A fixed identifier assigned to a test step.
• C. A global constant that never changes.
• D. A separate entity used for reporting.

Answer: (A)

Dynamic ID refers to a property value on a Module Attribute that can change during each run. In Tosca, UI elements are located using attributes defined in a Module. When the value used to identify an element isn’t stable—for example, an HTML id that the application generates anew every time—the attribute is treated as Dynamic ID. Marking it this way signals Tosca to locate the element using a flexible or parameterized value rather than a fixed one, ensuring reliable identification despite changing identifiers. This isn’t about a fixed identifier, a global constant, or something used only for reporting—the dynamic ID specifically captures the need to adapt to identifiers that vary across executions.
