Method for evaluating software quality based on test data

Abstract

The invention discloses a method for evaluating software quality based on test data, which comprises the following steps: firstly, determining a case set evaluation formula for functional test and a case set evaluation formula for non-functional test; determining a sub characteristic evaluation formula of the software quality according to the case set evaluation formulas for the test; determining a characteristic evaluation formula of the software quality according to the sub characteristic evaluation formula of the software quality; and determining an evaluation formula of the software quality according to the characteristic evaluation formula of the software quality. The method determines the evaluation confidence level of the software quality, and determines a comprehensive evaluation formula of the software quality according to the evaluation result and the evaluation confidence level of the software quality. The method evaluates the software quality objectively, and has high accuracy.

Description

technical field [0001] The invention relates to a software quality evaluation method based on test data in software engineering. technical background [0002] With the development of information technology, computer software has penetrated into various fields of the national economy and is closely related to people's production and life. Therefore, the quality of software is increasingly concerned by people. "The quality of software products is the life of software companies", this point of view has become the consensus of the industry. Implementing software quality evaluation on software is another important means to promote software quality after software quality management and software testing. Software quality evaluation can quantitatively evaluate the quality level of software, accurately control, manage and improve software quality, and provide objective and fair scientific basis for software finalization, acceptance, appraisal and industrialization. [0003] The so...

Problems solved by technology

[0020] (1) The evaluation formula of the functional test case set does not consider the situation that one test case corresponds to multiple software problems

[0021] (2) The measurement of the difference degree of evaluation factors is given by manual review, which is easily affected by the subjective influence of review experts

[0022] (3) The model does not give a measure of confidence in the software quality evaluation results

[0023] These deficiencies make the evaluation results of software evaluation by existing quality evaluation methods not objective enough and less accurate
