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 class cluster testing method for object-oriented software, which constructs the software system to be tested as a directed loop network; traverses all class nodes in the directed loop network to calculate the test importance; traverses the directed loop network All strongly connected components of each loop, calculate the complexity of the test pile corresponding to each edge in each loop; assign a weight to each edge in the loop and perform loop removal operations; generate a class-level integration test sequence to be tested Software systems undergo cluster testing. This invention regards the error-prone classes in the software system and the classes with a larger scope after the error occurs as important test nodes, and combines the complexity of the class with the error propagation influence of the class to discover software defects as early as possible and effectively control errors. The propagation scope is the test target, and the test importance of the class is combined to break the loop of the software system network and generate an integrated test sequence, which not only ensures that nodes with high test importance are tested first, but also reduces the overall complexity of the test pile.

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 ...
