NIST Tool Enables More Comprehensive Tests on High-Risk Software
With the research toolkit called Automated Combinatorial Testing for Software, or ACTS, software companies can make sure that there are no simultaneous input combinations that might inadvertently cause a dangerous error. As a rough parallel, think of a keyboard shortcut, such as pressing CTRL-ALT-DELETE to reset a system intentionally. The risk with safety-critical software is that combinations that create unintentional consequences might exist.
NIST’s ACTS toolkit now includes an updated version of Combinatorial Coverage Measurement (CCM), a tool that should help improve safety as well as reduce software costs. The software industry often spends seven to 20 times as much money rendering safety-critical software reliable as it does on more conventional code.
