Improving test coverage of LAPACK

摘要

We discuss the way in which the LAPACK version 3.0 suite of software is tested and look at how the application of software testing metrics affects our view of that testing. We analyse the ways in which some errors may be masked by the existing approach and consider how we might use the existing suite to generate an alternative test suite that is easily extensible as well as providing a high degree of confidence that the package has been well tested.
