Embodiment Construction

[0040] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] A class cluster testing method for object-oriented software, such as figure 2 shown, including:

[0042] Step 1: Construct the software system to be tested as a directed loop network with classes as nodes and inter-class dependencies as edges;

[0043] Step 1.1: Use the code analysis tool DependencyFinder to read the compiled jar package of the software system to be tested, analyze the tree structure by scanning and analyzing the syntax, and export the XML file that stores the inter-class dependencies of the software system to be tested;

[0044]Step 1.2: Use the XMLParser parser to parse out the classes, modules, interfaces, functions, attributes and dependencies between them in the software system to be tested from the XML file, and filter out the tool classes and tools in the Java virtual machine contained in the XML file. meth...

Abstract

The invention provides a project-software-oriented class cluster test method. A software system to be tested is constructed into a directed loop network; all class nodes in the directed loop network are traversed to calculate the test important degree; all strong communication components in the directed loop network are traversed, and the test pile complexity corresponding to each edge in each loop is calculated; a weight value is aligned to each edge in the loop, and the loop removing operation is performed; a class stage integrating test sequence is generated for performing class cluster test on the software system to be tested. The method has the advantages that classes easily generating errors in the software system and classes with a wide affected range after the error occurrence are regarded as important test nodes; the class complexity and the class error spreading influence power are combined, and the goals of discovering the software defect as soon as possible and effectively controlling the error spreading range are used as test objectives; the test important degree of the class is combined for breaking through the loop of the software system network; the integrated test sequence is generated; the nodes with great test important degree value is enabled to be tested in a preferential way; the general complexity of the test pile is also reduced.

Description

technical field [0001] The invention relates to the field of software reliability research, in particular to a class cluster testing method for object-oriented software. Background technique [0002] The integration test sequence refers to the order in which classes are tested successively determined by the dependencies between classes in the class cluster test of object-oriented software. The main idea of ​​integration testing according to the test sequence is to ensure that the class nodes that do not depend on other classes are tested first, and then test those class nodes that depend on the tested classes, which can effectively reduce the construction of test stubs and test drivers, so as to achieve The purpose of reducing the cost of testing. If there is no cycle in the inter-class dependencies of the software system, the integration test sequence can be generated directly by reverse topological sorting. However, in the actual operation process, the complexity of the ...
