TruClient is a tool for recording web-based applications. The TruClient engine records your actions as you navigate through your business process. It creates a script in real-time, allowing you to see the steps as they are performed in a sidebar.
For details, see the TruClient Help Center (select the relevant version).
If you are working locally, you can open the TruClient Help Center from the Windows Start menu, from Micro Focus > LoadRunner > Documentation.
