We investigate the evolution of a medium sized software package, LAPACK, through its public releases over the last six years and establish a correlation, at a subprogram level, between a simply computable software metric value and the number of coding errors detected in the released routines. We also quantify the code changes made between issues of the package and attempt to categorize the reasons for these changes. We then consider the testing strategy used with LAPACK. Currently this consists of a large number of mainly self-checking driver programs along with sets of configuration files. These suites of test codes run a very large number of test cases and consume significant amounts of cpu time. We attempt to quantify how successful this testing strategy is from the viewpoint of the coverage of the executable statements within the routines being tested.
