Computer software test coverage analysis

摘要

A computer implemented method, apparatus, and computer usable program code for performing software testing. A first set of traces is compressed to form a first set of compressed traces. The first set of compressed traces is compared to a plurality of additional traces to identify a set of partially matching traces within the plurality of additional traces. The first set of traces is compressed to form a second set of compressed traces. The second set of compressed traces is compressed according to a technique such that the second set of compressed traces contains more information than the first set of compressed traces. The second set of compressed traces is compared to the set of partially matching traces to identify a second set of partially matching traces within the set of partially matching traces. The second set of partially matching traces is placed in a memory.
