Problems solved by technology

Based on the 1999 paper, Elbaum et al. made some improvements. First, relative to the statement and branch coverage granularity, the coarse-grained function coverage was increased, and it was confirmed that the coarse-grained sorting method can reduce program overhead, but it will also reduce the sorting effect.

Abstract

The invention discloses a method and system for prioritizing test case sets based on dynamic feedback weights. Step 1 is to collect code coverage information of the test case set according to the operation of the test case set on the basic version program set; step 2 is to convert the test case set The set is run on the iterative error version to obtain the error detection status of the test case set on each version; step 3, use the dynamic feedback weight sorting method to sort the test cases according to the obtained code coverage information, and output the sorted test case sequence; Step 4, according to the sorted test case sequence and the error detection situation of the test case set, calculate the evaluation value of the test case sequence and perform statistical analysis. In the sorting process, compared with the traditional greedy algorithm, the covered statements are no longer considered or completely discarded. As the number of covered sentences increases, the inverse proportional weight value is set, which reduces the randomness in the sorting process and improves the test cases. The efficiency of sequence detection errors.

Description

technical field [0001] The invention belongs to the field of software testing, and relates to a test case priority sorting method based on dynamic feedback weights. Background technique [0002] From the software development life cycle, we can find that software engineering is not only software development and programming language, software testing occupies a large part, especially in software iterative regression testing, in fact, regression testing is an effective method , which can ensure partial modification of the code and bring some errors to the tested program, and the data shows that regression testing generally accounts for about 80% of the software testing budget and half of the entire software maintenance budget. Therefore, in order to reduce the cost of regression testing, the industry and academia have proposed a series of technologies based on test maintenance, including test case sorting TCP (Test Case Prioritization), test case selection TCS (Test Case Select...
