Generally UFT supports three kinds of features.
Direct Features – Features that are built-in with a UFT tool window like Data Table, Object Spy, Step generator etc.
HP Integrated Tools – These tools can be automatically installed if the UFT is installed. Example: Test Batch Runner, Password Encoder, etc.
Other Integrated Tools – If we want to use these tools, then a user needs to install them. Example: VB Script, SQL etc.
