Output Parameter: Enables you to use output to capture values from the Application at run-time. You can get a value from the application and store it in the QuickTest Test Results. You can later use this value as an input to a variable.

Using Output Parameters:

An Output parameter is the value of a property captured from the aut during test execution. When you run a test, QuickTest retrieves the value of the property and enters it in the run-time Data table as an output value. You can then use this output value as an input variable in your test. Capturing a value during run-time and using it as an input variable in your test is called data correlation.
