Abstract

The invention provides a software reliability accelerated test and evaluation method based on a deformed operational profile as well as a computer-aided tool used in the same, and belongs to the field of software reliability engineering. In the method, the deformed operational profile is constructed, and then software reliability growth and verification accelerated test and evaluation are carried out on tested software based on the profile. By using the tool, a traditional operational profile is constructed by a traditional operational profile construction module, the deformed operational profile is further constructed by a deformed operational profile construction module, a reliability verification accelerated test module and a reliability growth accelerated test module are executed according to selection of a user, and cases in test are generated by an automatic test case generation module. By adopting the software reliability accelerated test and evaluation method provided by the invention, unbiased estimation of reliability parameters between the deformed operational profile and the traditional Musa operational profile is realized and the test efficiency is better; and compared with the traditional test method, the method has the advantages of short test time and accurate test result, thus facilitating understanding and practical operation of engineering personnel.

Description

technical field [0001] The invention belongs to the field of software reliability engineering, in particular to the field of software reliability testing and evaluation, and specifically refers to a method for accelerated testing and evaluation of software reliability based on distorted operation profiles and a computer-aided tool thereof. Background technique [0002] Software reliability testing is of great significance to software quality assurance. On the one hand, it is necessary to continuously eliminate software defects that have an important impact on software reliability through software reliability growth testing, and to achieve continuous growth of software reliability levels to meet user expectations for software. Reliability requirements; on the other hand, it is necessary to pass software reliability verification tests to determine whether the software has reached the required reliability level, and then determine whether the software can be received or released...
