Method and system for performing parametric testing of a functional programming interface

摘要

The present invention provides a method and system for performing parametric testing of a functional programming interface. Parametric testing of a function verifies that the function performs as expected when a valid or an invalid parameter is passed to the function. To perform parameter testing on a function, the present invention receives as input prototype information for the function, and then formulates a testing plan. The invention tests the function according to the testing plan. The testing plan specifies a list of invalid and valid values for each parameter of the function. The invention repeatedly invokes the function, each time passing the function various combinations of invalid and valid values. The function passes the test when (1) the function does not return an error code for any combination of valid parameter values and (2) the function returns an error for any combination of parameter values that include an invalid parameter value.
