A Framework for Testing Real-Time and Embedded Systems

What do we mean when we say local, remote, simultaneous, and distributed testing? Alan Haffenden of The Open Group explores the differences, and explains why the architecture of a distributed test execution system must be different from that of non-distributed systems. An overview of POSIX 1003.13 profiles and units of functionality helps advanced users build a good foundation for testing both their real-time and embedded systems.
