Empirical Studies of Test Effectiveness and Delivered Reliability

چکیده
White-box testing techniques based on control flow and data flow analysis have been widely studied in the software testing research literature, but there is no definitive answer to the question of how effective these techniques are at finding software faults. In the absence of data indicating how effective (and how expensive) these techniques are, it is hardly surprising that they have not been adopted widely in practice. On the other hand, there is no easy answer to this question. Meanwhile, many analytical and empirical studies of software testing effectiveness have used the probability that a test set exposes at least one fault as the measure of effectiveness. That measure is useful for evaluating testing techniques when the goal of testing is to gain confidence that the program is free from faults. However, if the goal of testing is to improve the reliability of the program ( as determined by the probability that the program will fail when executed on an input randomly selected

متن کاملEstablishing an Argument-Based Validity Approach for a Low-Stake Test of Collocational Behavior
Most of the validation studies conducted across varying test application contexts are usually framed within the traditional conceptualization of validity and therefore lack a comprehensive framework to focus on test score interpretations and test score use. This study aimed at developing and validating a collocational behavior test (CBT), drawing on Kane's argument-based approach to validity. F...
