Problems solved by technology

Reference 6 establishes a system of measurement indicators for the entire testing process, many of which cannot be used as factors for judging the adequacy of test criteria, such as code walkthroughs, etc.
However, its measurement index system is not satisfactory, resulting in inaccurate final evaluation results

Abstract

The invention provides a method for acquiring test adequacy on the basis of function call path criteria. The method includes steps of 1, determining indexes in test criterion adequacy metric index systems by the aid of GQM (goal question metrics) normal forms; 2, computing and comparing test adequacy of a plurality of test criteria by the aid of data envelopment analysis processes which are used as decision-making processes in the index systems.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for obtaining test adequacy based on function call path criteria. Background technique [0002] The quality of software testing determines whether the software system can operate reliably according to the requirements, and the test results obtained by using different testing criteria in the testing process are also different, and the adequacy of software testing is the only criterion for testing the quality of software testing criteria. Based on the function call path criterion, the analysis granularity of path coverage is extended from statement to function level, which not only reduces the test workload exponentially, but also ensures the test effect. [0003] In software testing, testers should test all combinations in the input field of the software, but this is time-consuming and labor-intensive and impossible to achieve. In the actual testing process, testers en...
