When should I use TxP (Internet Explorer) to record a test script?
The Real Browser service, TxP, should be used to record any Web application transaction that simulates a user navigating and interacting with a site. TxP will provide full IE functionality, rendering every page and summoning any plug-ins that are required by the site. Some Web pages and applications can only be monitored using the Real Browser (TxP) service because they rely on asynchronous communications (AJAX), requiring logic to be executed in the browser to support the user interface. An example might be a transaction where the browser must render complex AJAX content in order to reveal the login fields.
