Combined test method for combining software reliability tests with hardware reliability tests

Abstract

The invention discloses a combined test method for combining software reliability tests with hardware reliability tests. The combined test method is used for testing the reliability of software and hardware systems. The combined test method includes analyzing the software and hardware systems and constructing hardware reliability test profiles and software reliability test profiles; enabling software and hardware scenarios to be orthogonal to one another to acquire system task scenarios and determining execution probabilities of the system task scenarios; creating relation matrixes for determining whether the software reliability test profiles and hardware scenario profiles are associated with one another or not; combining corresponding hardware environmental stress test profiles with the associated software reliability test profiles to generate stage child profiles for each system task scenario; organizing the stage child profiles of the same system task to form a periodic child profile, organizing the periodic child profiles according to test cycle periods to generate final combined test profiles; generating test cases according to the combined test profiles and performing the tests. The combined test method has the advantages that the reliability of the systems can be accurately evaluated by the aid of test results generated by the method, and system failure which cannot be discovered in traditional reliability tests can be discovered by the aid of the combined test method.

Description

technical field [0001] The invention is applied to the field of reliability testing of software and hardware systems, and specifically relates to a combined testing method combining software reliability testing and hardware reliability testing. Background technique [0002] With the continuous improvement of the informatization level of national defense weaponry and aerospace equipment, the application of software and hardware systems, especially embedded systems, has become more and more extensive, and more and more attention has been paid to the reliability research of such systems. Since the software and hardware of the software and hardware system are more and more closely integrated, it is difficult to simply divide the system into software and hardware. It is the reliability of the system when the hardware and software are combined. Reliability identification through the separation of hardware reliability test and software reliability test is not suitable for complex ...
