Embodiment Construction

[0045] The method of the present invention will be further described in detail below in conjunction with the drawings and the embodiments of the present invention.

[0046] The method for automatically locating software faults in unit testing of the present invention proposes an automatic locating technology for faults in unit testing based on two execution modes under multi-type coverage, and the two execution modes are considered separately from the perspective of users. For the fully automatic mode, a group of test cases will be executed at the same time, and the more common situation is that once a certain wrong test case is executed, the test is stopped for fault finding. Therefore, the method of the present invention can separately perform two The execution mode automatically locates software faults. Taking the edge on the corresponding control flow graph of the program as the covering unit, the program will fail, and the path execution trajectory will inevitably change. Tw...

Abstract

The invention provides an automatic positioning method of software failures in a unit test. The automatic positioning method comprises the following steps: A. adopting a group of test examples meeting the covering requirements, executing a tested program, and judging whether the executing result of the test examples is identical to an expected result or not; B. analyzing edge information on a path according to an executing path corresponding to each test example and determining a suspicious space formed by edges on the path; C. performing statistics on covering times of the test examples passed or not passed for each edge in the suspicious space and calculating the degree of suspiciousness of each edge under an appointed executing mode; D. calculating the degree of suspiciousness of a node of an adjacent sentence; and E. sequencing failure nodes according to the degree of suspiciousness and mapping orderly to the tested program to generate a failure positioning report to assistant the user to examine the failures. With the adoption of the method provided by the invention, the calculating workload of sentence analysis can be reduced, and the failure positioning efficiency is improved by taking logic relationships among the sentence nodes into consideration.

Description

Technical field [0001] The method relates to a fault location technology in software testing, and more particularly to a method for automatically locating software faults in unit testing. By executing test cases, according to whether the execution results are consistent with the expected test results, faults existing in the software are automatically located. Background technique [0002] Software failure is a dynamic behavior. If a software failure occurs without proper measures to deal with it in time, software failure will occur. Finding and eliminating as many faults as possible in the unit test as early as possible will reduce and avoid wasting too much unworthy time later. [0003] At present, most of the research on software fault location technology is based on whether the execution result is passed, and the program statement is used as the coverage node for statistical analysis. When the program code is large, the calculation amount of sentence analysis is large, which ...
