Many test strategies are proposed and used today, but how to compare them to show which one is more cost-effective than others ? In this article, we establish a formula to evaluate the averaged fault-detecting-ability (FDA) per test case of test strategy M under some test sets of M, to be an index of the efficiency of a test strategy. In this formula , we consider not only the effectiveness of test strategy but also the cost of test. Since the size of test set is often too large, we propose a method, partitionong the input domain into subdomains, to reduce the size of test set for the tester. Finally, we experiment with various test strategies for some programs, getting the comparative basis from the results, and concluding which test strategy is better than others among these test strategies.
