Under the conditions of ensuring the reliability test effectiveness, the reliability test efficiency is improved, and better feasibility and effectiveness are realized.

Description

technical field [0001] The invention belongs to the field of software reliability engineering, and mainly relates to the field of software reliability testing. Specifically, it refers to a method for generating software reliability testing data based on orthogonal test design and a computer-aided tool thereof. Background technique [0002] Software reliability is the most important attribute in software quality of weapons and equipment. The level of software reliability directly affects the combat readiness of equipment and the successful completion of tasks. In order to ensure the reliability of the weapon equipment system, the reliability of the software must be guaranteed. Therefore, it is particularly important to put forward quantitative requirements for software reliability, and to realize this requirement and verify whether the requirements are met through software reliability testing. [0003] The core idea of ​​software reliability testing is that the test input sim...
