Software Testing Method and System

A software product is tested by first obtaining a performance matrix for the software product, the performance matrix containing the profile results of a plurality of tests on the software product, and an expected result vector for the plurality of tests. A test sequence is then executed for the software product, the sequence comprising selecting a subset of the plurality of tests, running the test subset to obtain a new result vector for the test subset, comparing the new result vector entry with the expected result vector entry for the same test, selecting a test (which may be one of the subset or may be a new test) according to the outcome of the result vector comparison and the performance matrix, and running the selected test under profile.
