Problems solved by technology

The prioritization method of combined test cases with variable strength has the following problems: it is difficult to select the combination strength during the sorting process, and the current prioritization method of combined test cases with fixed strength cannot satisfy the complex interaction relationship
Moreover, in the prioritization method of combined test cases with variable strength, the influence of other factors is ignored, and the situation of test feedback result information in the actual test process is not considered.

test Embodiment t

[0044] where tc is the test case, t i is the current moment, λ is the combined coverage strength, is the partial combined coverage of test case tc. Denotes the test case tc, t i Cover all λ-element combinations in the local impact factor set R at the moment, and these λ-element combinations have not been tested by the test case sequence probability of coverage. is the test case tc failure rate. Indicates that during the test, t i The failure rate of the time test case tc. I (tc,R) is the importance of the test case tc. α, β, γ represent the weights of partial combined coverage, test case failure rate and test case importance respectively, and α+β+γ=1.

Abstract

The invention discloses an OTT policy-based variable intensity combination test case priority online sorting method and belongs to the field of software testing. The method comprises the steps of adjusting an influence factor set according to a current test case sequence coverage combination condition; through an OTT policy thought, selecting a test case with a highest priority to be executed froma combination test case set each time; calculating and ranking test case priorities by using three influence factors including a local combination coverage rate, a test case failure rate and test case importance; according to test results of test cases, adjusting parameter values of the influence factors in real time, and updating a test case sequence, the test case set and a non-covered combination set of the test case sequence; and re-calculating the priorities, and repeating the process until a test goal is achieved. The method can be used for ranking the test case priorities generated bydifferent combination coverage intensities; and more defects can be effectively detected out under the condition of using the same test case quantity, so that the defect detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of software testing, and in particular relates to an OTT strategy-based variable strength combination test case prioritization method. Background technique [0002] In today's era of rapid development of computer technology, users' demand for existing products is getting higher and higher, and the update rate of software products is also increasing. In this case, users not only require to reduce the product development cycle, but also require to improve the quality of the product. However, for developers, how to efficiently develop new products and improve product quality has become a difficult problem. From the perspective of testing, how to improve testing efficiency and defect detection capability is the key link to solve this problem. [0003] The introduction of test case priority technology makes it possible to avoid exhaustive testing and repeated testing during the testing process. In order to achieve the t...
