Augmenting a software module test suite is provided, which includes: providing a test suite including test cases for a module to convert an N-dimensional space into an output space, where N≥2, the cases covering a first portion of the N-dimensional space; exploring the N-dimensional space by repeating: partitioning a further portion of the N-dimensional space by exploring a partition of the further portion, the partition including partition boundaries defined by a constant value of one of the N input values, each partition having a partition boundary bordering one of the test cases; evaluating the partition and generating a further test case if the evaluation reveals that the partition is not covered by the test cases; and adding the partition to the first portion; until the further portion has been explored or a termination criterion met; and producing an augmented test suite including the generated further test cases.
