A Practical Guide to Testing Object-Oriented Software

Basic Concepts

The basic unit that we will deal with in this chapter is a thread. A thread is an independent context of execution within an operating system process. It has its own program counter and local data. A thread is the smallest unit of execution that can be scheduled. Most modern operating systems allow a single process to group multiple threads into a related set that shares some properties and keeps certain others private. A single thread is a sequence of computations and is the simplest testing situation. Techniques discussed in earlier chapters have “covered” the various entry points into and the paths through a single thread of computation. The techniques have accounted for alternative paths through the logic including the dynamic ...
