A Controlled Experiment to Evaluate Effectiveness and Efficiency of Three Software Testing Methods

In this paper, we describe a controlled experiment carried out to compare three software testing methods: code reading, functional testing and structural testing. The experiment was carried out with eighteen subjects who applied three techniques to three C programs in a fractional factorial experimental design. The main results of the study are that all testing techniques are equivalent in terms of effectiveness; however the techniques differ partially in terms of efficiency.
