During a run session, UFT attempts to identify each object in your application by matching the description properties stored for the corresponding test object with the properties of the DOM element in the application. For complex Web applications that contain many objects, using only the standard identification methods may have unreliable results.
You can instruct UFT to use Web object identifiers before the regular object identification process to help limit the number of candidate objects to identify. UFT accesses the application's DOM and returns objects that match the object identifier property values. UFT then continues to identify this smaller set of returned objects using the normal object identification process. Therefore, using Web object identifiers can lead to a more reliable and accurate object identification, and a quicker object identification process.
