  • Arrangement for generating an optimal set of verification test cases
    Patent number: 5159600
    Abstract: A facility is provided for generating from a series of parameters (factors) and their respective values (levels) inputted by a user a plurality of test cases using an orthogonal array selected from a library of such arrays, in which the selection is optimized by characterizing the arrays by respective cumulative level vectors and converting the user input into a cumulative level input vector. The smallest array for generating the test cases is then selected on the basis that the values of the input vector are no larger than the corresponding values of the cumulative level vector characterizing the selected array.
