Telerik Test Studio Tip: Use regular expressions for identifying dynamic pages, frames, elements

Another challenge in automation is, handling elements whose identification logic will change dynamically. Assume the cases like, we are using URL for identifying page but some part of the URL is dynamic, we are using ID for identifying element but ID is appending with time stamp, frame name is dynamic. In such cases, it is recommended to use regular expressions in identification logic to identify multiple elements with same identification logic avoid duplication and reduce Element Repository size which ultimately reduces complexity.
