Embodiment 1

[0148] A technology for automatically generating software test cases, the specific steps are:

[0149] Step 1. According to the software structure, respectively generate packet-level and class-level software networks. The specific steps are:

[0150] Step 1.1, set up a software system consisting of 5 classes and 2 packages, and abstract all classes into a class node set VC={vc 1 ,vc 2 ,...,vc 5},vc 1 ,vc 2 ,...,vc 5 Represents the nodes in the class node set, and all the static and dynamic dependencies between nodes are abstracted as the inter-class edge set EC={ic ,vc jc >|vc ic ,vc jc ∈VC}, vc ic and vc jc Represents any two nodes in the class node set, ic,jc∈{1,2,…,5}, n is the number of classes, that is, n=5, and the inter-class relationship of the software system is expressed as a directed network GC = (VC, EC), GC is the class-level software network;

[0151]Step 1.2, abstract all packages into a package node set VP={vp 1 ,vp 2}, vp 1 ,vp 2 Represents the ...

Abstract

The present invention proposes a kind of software test case automatic generation method, comprises the following steps: step 1, according to software structure, generate package level, class level software network respectively; Comprehensive importance; step 3, according to the class-level and package-level software network structure, calculate the dependency strength between nodes in each network, and then determine the state probability and transition probability; step 4, according to the hidden Markov model, automatically generate for the software test case. The method for automatically generating software test cases of the present invention provides a method for automatically generating software test cases from the perspective of node importance and comprehensively considering graph topology, and the results have high credibility.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a method for automatically generating software testing cases. Background technique [0002] Due to the characteristics of encapsulation, polymorphism and inheritance, object-oriented software is very different from traditional process-oriented software in software testing technology. Among them, the class integration test is the test of the class integration process on the basis of the completion of the class unit test. Because the test order of classes is related to the time of software defect discovery and the test cost caused by designing test stubs, the order of class integration testing becomes an important issue in integration testing. [0003] At present, there are mainly two types of generation methods for inter-class integration test sequences: (1) Inter-class integration test sequence generation methods based on genetic algorithms. This method first initializ...
