NIST Covering Array Tables

The tables of covering arrays that are accessible from this website are maintained as part of the Automated Combinatorial Testing for Software (ACTS) project at NIST. An important component of this project is the development of covering arrays for use in the design of small but effective test sets for combinatorial testing. Software to produce a covering array of given size on demand, called FireEye, is under production by the ACTS team. The covering arrays accessible here were produced by IPOG-F, an enhanced component of the FireEye software. It is intended that the tables will be augmented by results from FireEye and by contributions of especially noteworthy covering arrays from the public.
