Can full selectors be used inside a container (Attach Window or Open Application activities)?

Full selectors can indeed be used inside a container, such as Attach Window or Open Application activities. Full selectors provide a complete, absolute path to a UI element and include all necessary information like the application type, element type, and many attributes that unequivocally identify the UI element.

Using full selectors in activities like Attach Window or Open Application is beneficial because it enhances the reliability and accuracy of the automation. These activities require a strong reference to the specific element intended for automation, and full selectors help in achieving that by ensuring that the automation interacts with the correct element, regardless of any dynamic attributes that might change during runtime.

While there may be considerations regarding performance and maintainability with full selectors, particularly in applications with frequently changing UI elements, the fundamental capability to use them within containers is intact. Other options might hint at limitations that do not exist for the use of full selectors in context with these activities.
