A Designing Method for Function Combination Testing Based on Orthogonal Chart
Ruonan Rao · Microcomputer applications · 2007
Software testing has become increasingly important in software development.Its importance has been extremely un- derlined today when software often features with multiple functions and a test is necessary to examine whether these functions could co-exist harmoniously.However,tests on any software function combinations are unpractical if no pre-condition is given beforehand as they would lead to testing staffs exhausted by endless testing projects.Orthogonal chart is an effective way in helping testing staffs to get rid of unnecessary tests due to unscientific project designs.In the paper,the author depicts in details a new testing method on software function combination based on the theory of orthogonal chart and its adoption in practice.Fur- thermore,the author introduces a tool especially on creating test cases accordingly.With the adoption of the new testing method,testing staffs could scientifically combine functions of test targets and make sure they could test as many functions of target software as possible by using just a few testing cases.It has been proved that,compared with traditional testing methods, the new method based on orthogonal chart could double the coverage of test cases on targeted software,detect bugs by three times and shorten time on test case designing by one sixth.
