Test Complete is perfectly able to use custom attributes like "data-blah" to find objects but TestComplete is hiding them in the Available properties list. That make us have to do some extra steps for each object to add this custom properties in mapped objects.
That really will help to the people how is automating angular websites because angular also uses custom attributes like ng-switch, ng-switch-when, sv-busy-click etc.
As I said, TestComplete can find objects only using this attributes but would help to show them in available list properties.
