Abstract

The invention discloses a metamorphic relation testing priority ranking method based on quantitative measurement. The method includes: based on testing coverage, measuring in-degree of input relations of metamorphic relations, measuring complexity of output relations, and measuring spacing of relevant test inputs of the input relations to obtain three effectiveness metric units for the metamorphic relations. When results of the three effectiveness metric units are inconsistent, ranking is performed according to PIR (InD(IR)) > PIR (AC(OR)) > PIR (Dis(IR)). Through the application of the three metric units, metamorphic relation testing priorities can be quickly ranked without prior test execution. The metamorphic relation testing priority ranking method based on quantitative measurement has the advantages that quantitative basis is provided for the effectiveness measurement of metamorphic relations, feasible means is provided for setting testing priorities; through the application of quantitative measurement, the method compared to traditional experiential conclusions is simpler, more accurate and more feasible, the application range of priority design is guaranteed, and the precise, effective method is provided for the selection and ranking of metamorphic relations.

Description

technical field [0001] The invention relates to a method for prioritizing a metamorphosis relationship test based on quantitative measurement, relates to a formalized description and decomposition method of a metamorphosis relationship, and belongs to the technical field of software metamorphosis testing. Background technique [0002] In software testing, it is often assumed that test judgments exist, which is also known as test judgment assumptions. However, this assumption is often difficult to hold in practice. Because in many cases, the cost of verifying the correctness of a test case execution result is very high, even impossible to verify under the existing conditions. This is the usual sense of the "test decision problem." In addition, under some other conditions, even if the test judgment can be obtained, this method of obtaining the test judgment cannot be realized automatically, and also requires the participation of manual activities. At this time, manual verif...
