Problems solved by technology

There are many defects in the implementation process of this test method, mainly including the following aspects: 1) The accuracy of the operation profile is not high: when the software is running, the execution logic is often unpredictable, the usage scenarios are complex and changeable, the data interaction is frequent, It is very difficult to accurately describe the software usage and its probability information for complex features such as difficult to measure operating rules; It was not used in the software reliability testing process, resulting in early software failure information not being effectively transmitted to the testing stage. Targeted testing was not carried out for software failure modes in the software rel...

Abstract

The invention provides a test data generation method for software reliability, which comprises the steps of software failure mode analysis, software space analysis, mapping and test data generation. According to a software failure mode obtained at an early stage of a development phase and analysis of the software space, the software input variable, the output variable, the value space of the variable, the value rules and the constraint conditions of the variable in the value space are determined, then the failure mode is mapped to the software space, finally, the test data are generated basedon the mapping function of the failure mode and the software space according to the possible input of the software when the software is in use. The early information of the development phase is utilized, so the ability of expose defects of the test case is improved and the repetition of the test case is reduced.

Description

technical field [0001] The present application relates to the technical field of software testing, in particular to a method for generating test data for software reliability. Background technique [0002] At present, the mainstream technology is the method of generating and executing software reliability test cases based on the operation profile. There are many defects in the implementation process of this test method, mainly including the following aspects: 1) The accuracy of the operation profile is not high: when the software is running, the execution logic is often unpredictable, the usage scenarios are complex and changeable, the data interaction is frequent, It is very difficult to accurately describe the software usage and its probability information for complex features such as difficult to measure operating rules; It was not used in the software reliability testing process, resulting in early software failure information not being effectively transmitted to the te...
