Provided is a system and method for black-box testing of software using positive and negative test cases with N-way combinations of parameter values that solves the problem of input masking. An original model comprising valid and invalid values is modified in a first phase, by generating exclusions (constraints) for pairs of invalid values. A first suite of test cases is generated from the modified model, and positive test cases eliminated, creating a first test suite with only negative tests. In a second phase, the original model is modified by eliminating invalid values, from which a second test suite having only positive test cases for all valid N-way combinations is generated. Merging the two test suites provides a suite of positive and negative test cases that thoroughly test software with N-way combinations of values, in which each negative test case has only one invalid value, thereby preventing input masking.
