EXPERIENCE WITH THE COST OF DIFFERENT COVERAGE GOALS FOR TESTING

In coverage-based testing, coverage conditions are generated from the program text. For example, a branch generates two conditions: that it be taken in the false direction and in the true direction. The proportion of coverage conditions a test suite exercises can be used as an estimate of its quality. Some coverage conditions are impossible to exerise, and some are more cost-effectively eliminated by static analysis. The remainder, the feasible coverage conditions, are the subject of this paper.
