Parameters facilitate re-usability of an Action or a Test. By using parameters, you can record a test once and use it several times. Parameters enable you to run multiple sets of data.
Note: An input Parameter is a placeholder for a value that is passed to the test during the test run.

Parameter Types: By default, a test runs once for the recorded values. To run a test for multiple values,parametrize the test. The types of parameters in QuickTest are:

  1. Input parameter: Enables you to run a test using different sets of input values.
    For example, you can use input parameter to select different destinations for the same source in the Flight
    Reservation Application.
  2. 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.
  3. Random Number parameter: A system-generated number that is generated during a test run.
  4. Environment parameter: A variable that describes a software or hardware object in the application under test environment. Examples are operating system version or Local host name.
