To make a UI selector stable, what practices should be followed?

A UI selector is a critical part of RPA that defines how a robot identifies and interacts with user interface elements. To enhance the stability of a UI selector, it is important to select fixed properties whenever possible. Fixed properties are attributes that are less likely to change and provide a reliable means of identifying elements on the UI. Unlike dynamic properties, which can vary based on different conditions (like system states or changing data), fixed properties maintain consistency across sessions.

Using "Attach to Live Element" is also a key practice because this feature allows the RPA tool to automatically adjust to changes in the UI context. When the selector is attached to a live element, it can adapt dynamically when the position or state of the element changes—this further boosts the resilience of the automation.

Choosing dynamic properties would lead to instability, as these can change frequently based on user actions or system updates. Also, selecting elements based purely on appearance can lead to errors since visual aspects can vary based on themes, screen resolutions, or user settings. Relying solely on an element’s ID might not be viable in certain applications where IDs can change or be reused frequently, which could cause failures in the automation process.

Therefore, following the practice of utilizing fixed properties combined with the "
