Testing / Ranorex Interview questions
How do you handle dynamic UI elements in Ranorex?
Dynamic elements - ones whose ID, index, or visible text changes between runs - are handled by relying on stable attributes instead of the values that shift.
The most reliable option is to locate the element by an attribute that the developer sets deliberately, such as an AutomationId or a name that doesn't change with locale or content, rather than by visible text or sibling position.
When no single attribute is fully stable, RanoreXPath supports regular-expression matching on an attribute (for example, matching an ID that always starts with "row_" followed by any digits) and variables that a test module fills in at run time, so the same repository item still resolves correctly even as the underlying value changes.
For elements that only appear after some delay - a spinner finishing, an async list populating - the fix is a generous but bounded wait condition (an Exists timeout) rather than a fixed Sleep, so the test proceeds as soon as the element is ready instead of always waiting the worst-case amount of time.
