Controllable testing from nondeterministic finite state machines with multiple ports [PDF]

open access: yes, 2011
Copyright @ 2011 IEEESome systems have physically distributed interfaces, called ports, at which they interact with their environment. We place a tester at each port and if the testers cannot directly communicate and there is no global clock then we are ...

Mutation testing from probabilistic finite state machines [PDF]

open access: yes, 2007
Mutation testing traditionally involves mutating a program in order to produce a set of mutants and using these mutants in order to either estimate the effectiveness of a test suite or to drive test generation.
