Test evaluation of software testing

　　 The goal of the test evaluation

　　1、 Quantify the test process

　　2、 Generate a summary report of defects and test coverage

　　 Problems of test evaluation

　　1、 The test coverage is not taken as the basis for reporting the test process , So I don't know whether the test is over ;

　　2、 No defect evaluation , Defect evaluation is an important indicator to measure the feasibility of software ;

　　3、 Do not use special software tools for data input tasks and corresponding evaluation activities , These tasks become heavy and tiring .

　　 Test coverage

　　 Criteria for evaluating how many tests have been completed

　　

　　 Defect assessment

　　 An important indicator for evaluating software quality , Generally, evaluation models assume that the discovery of defects is Poisson distribution ; Strict defect evaluation should consider the time interval between defects found in the test process . The evaluation is to estimate the current reliability of the software and predict that as the test continues , How can software reliability be improved .

　　SQA Suite Four forms of defect evaluation are provided ：

　　1、 The defect distribution report can generate a function of the number of defects and defect attributes . How to test requirements and status .

　　2、 The defect trend report shows the trend of defect growth and reduction ;

　　3、 The defect age report shows how long a defect has been in a certain state

　　4、 The test result progress report shows the execution results and test cycle of the test process in several versions of the application under test .

　　 Specific steps

　　1、 Review test diary

　　2、 Assess the coverage of test requirements

　　3、 Analysis of defects

　　4、 Decide whether to meet the criteria for completing the test , When the standard is not met

　　1、 Retest

　　2、 Lower standards

　　3、 Determine a subset of the software that meets the criteria , See if it can be released .
