Parametrization in QTP

Test can be enhanced by parameterizing the values that it uses. A parameter is a variable that is assigned a value from an external data source or generator.

Following values can be parametrized:

•        Checkpoints

•        Object properties for a selected step

•        Operation arguments defined for a selected step.

•        One or more properties of an object stored in the local object repository. 

Values can be parameterized using:

•       Test/action parameters

•       DataTable parameters

•       Environment Variable parameters

•       Using Random number parameters

Following are the parameter types used for parametrization

Test/action parameters: Test parameters enable to use values passed from the test. Action parameters enable to pass values from other actions in the test.

Data Table parameters: Enables to create a data-driven test (or action) that runs several times using the data supplied. In each repetition, or iteration, QTP uses a different value from the data table

Environment variable parameters: Enables to use variable values from other sources during the run session. These may be values supplied, or values that QTP generates based on conditions and options

Random number parameters. Enables to insert random numbers as values in the test
