Embodiment Construction

[0046] The invention proposes an interface-oriented software fault injection automatic testing method, which can realize the automatic testing of interface fault injection. First obtain the cross-link interface relationship, communication behavior, and protocol data, then design the fault injection operator and model the test case, automatically generate the test case in XML format on the basis of this model, and finally automatically generate the test case in C++ language based on XSLT The test script calls the windows SDK to automatically generate and execute the test program, and realizes the result collection through the Windows pipeline technology.

[0047] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0048] figure 1 A flow chart of an interface-oriented software fault injection automated testing method is given, and the specific process is as follows:

[0049] The first step is to model the cross...

Abstract

The invention provides an interface-oriented automatic test method for software fault injection, and aims at realizing the automatic test of interface fault injection. The method comprises the following steps of: firstly carrying out cross-linkage interface modeling, communication behavior modeling and protocol data modeling; designing a fault injection operator and carrying out test case modeling; automatically generating an XML-format test case on the basis of the model; and finally automatically generating the test case into a test script of C++ language on the basis of XSLT, calling windows SDK to automatically generate a test program and automatically executing the test program, realizing result collection through a Windows pipeline technology, and evaluating the test result so as to complete the fault injection test of the whole cross-linkage interface. According to the method, universality and usability realized by an interface fault injection test tool are effectively improved, the interface test efficiency is improved and the test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to an interface-oriented software fault injection automatic testing method. Background technique [0002] Fault injection technology adopts the method of artificially introducing faults into the target system to accelerate the failure of the system, and evaluates the reliability of the system by observing the behavior of the system after a fault occurs. At present, fault injection can be divided into four categories from the technical realization: hardware-based technology, software-based technology, simulation-based technology and ion radiation technology. [0003] Software-based technologies include program mutation testing technology, module or component fault injection technology, software cross-link interface fault injection technology and system operating environment fault injection technology. Among them, environmental fault injection refers to the fault injection t...
