1. In a computational device providing a test environment, a method for conducting a test for testing units under test, the method comprising: enabling users to edit the test to include a sequence of one or more test steps for testing the units under test, each of the one or more test steps being of a type selected from a group consisting of a test step for testing a textual program, a test step for testing a graphical program, a test step for testing a function provided in a software tool and a test step for testing a hardware device; enabling the users to edit one or more independent parameters, an independent parameter defining a dimension of a parametric space, the parametric space including a plurality of points; generating code for the test; and automatically executing the code using defined values of the one or more independent parameters to produce output data from a number of executions of the test, elements of the output data corresponding to the plurality of points of the parametric space of the one or more independent parameters, wherein automatically executing comprises: using at least two independent parameters to execute the code, wherein at least one of the at least two used independent parameters has a plurality of defined values, determining the number of executions of the test by multiplying the defined values in each of the at least two used independent parameters; initializing a multidimensional parametric space for storing the output data generated from the number of executions of the test, dimensions of the multidimensional parametric space representing and corresponding to a product of the defined values in each of the at least two used independent parameters, and adding the output data to the multidimensional parametric space.
