一种基于程序切片技术的软件测试方法

1 引言软件测试是人们发现、纠正、预防软件错误以及完善软件功能的重要手段。软件测试的目的就是为了发现程序中的错误。对于传统程序设计语言书写的软件,软件测试人员普遍接受三个级别的测试:单元测试、集成测试和系统测试。无论在哪个级别上进行测试,其测试过程均为输入测试数据、处理和验证输出结果三个步骤。目前面向对象软件开发技术发展迅速,但面向对象软件测试技术的研究还相对薄弱。例如,对面向对象的程序测试应当分为多少级尚未达成共识。基于结构的传统集成策略并不适于面向对象的程序。这是因为面向对象的程序的执行实际上是执行一个由消息连接起来的方法序列,而这个方法序列往往是由外部事件驱动的,在面向对象语言中,虽然信息隐藏和封装使得类具有较好的独立性,有利于提高软件的易测试性和保证软件的质量,但是,这些机制与继承机制和

A practical model‐based statistical approach for generating functional test cases: application in the automotive industry

With the growing complexity of industrial software applications, industrials are looking for efficient and practical methods to validate the software. This paper develops a model‐based statistical testing approach that automatically generates online and offline test cases for embedded software. It discusses an integrated framework that combines solutions for three major software testing research questions: (i) how to select test inputs; (ii) how to predict the expected results of a test; and (iii) when to stop testing software. The automatic selection of test inputs is based on a stochastic test model that accounts for the main particularity of embedded software: time sensitivity. Software test practitioners may design one or more test models when they generate random, user‐oriented, or fault‐oriented test inputs. A formal framework integrating existing and appropriate specification techniques was developed for the design of automated test oracles (executable software specifications) and the formal measurement of functional coverage. The decision to stop testing software is based on both test coverage objectives and cost constraints. This approach was tested on two representative case studies from the automotive industry. The experiment was performed at unit testing level in a simulated environment on a host personal computer (automatic test execution). The two software functionalities tested had previously been unit tested and validated using the test design approach conventionally used in the industry. Applying the proposed model‐based statistical testing approach to these two case studies, we obtained significant improvements in performing functional unit testing in a real and complex industrial context: more bugs were detected earlier and in a shorter time.

A framework for table driven testing of Java classes

With the advent of object‐oriented languages and the portability of Java, the development and use of class libraries has become widespread. Effective class reuse depends on class reliability which in turn depends on thorough testing. This paper describes a class testing approach based on modeling each test case with a tuple and then generating large numbers of tuples to thoroughly cover an input space with many interesting combinations of values. The testing approach is supported by the Roast framework for the testing of Java classes. Roast provides automated tuple generation based on boundary values, unit operations that support driver standardization, and test case templates used for code generation. Roast produces thorough, compact test drivers with low development and maintenance cost. The framework and tool support are illustrated on a number of non‐trivial classes, including a graphical user interface policy manager. Quantitative results are presented to substantiate the practicality and effectiveness of the approach. Copyright © 2002 John Wiley & Sons, Ltd.     

Seeding strategies in search‐based unit test generation

Search‐based techniques have been applied successfully to the task of generating unit tests for object‐oriented software. However, as for any meta‐heuristic search, the efficiency heavily depends on many factors; seeding, which refers to the use of previous related knowledge to help solve the testing problem at hand, is one such factor that may strongly influence this efficiency. This paper investigates different seeding strategies for unit test generation, in particular seeding of numerical and string constants derived statically and dynamically, seeding of type information and seeding of previously generated tests. To understand the effects of these seeding strategies, the results of a large empirical analysis carried out on a large collection of open‐source projects from the SF110 corpus and the Apache Commons repository are reported. These experiments show with strong statistical confidence that, even for a testing tool already able to achieve high coverage, the use of appropriate seeding strategies can further improve performance. © 2016 The Authors.

MuJava: an automated class mutation system

Several module and class testing techniques have been applied to object‐oriented (OO) programs, but researchers have only recently begun developing test criteria that evaluate the use of key OO features such as inheritance, polymorphism, and encapsulation. Mutation testing is a powerful testing technique for generating software tests and evaluating the quality of software. However, the cost of mutation testing has traditionally been so high that it cannot be applied without full automated tool support. This paper presents a method to reduce the execution cost of mutation testing for OO programs by using two key technologies, mutant schemata generation (MSG) and bytecode translation. This method adapts the existing MSG method for mutants that change the program behaviour and uses bytecode translation for mutants that change the program structure. A key advantage is in performance: only two compilations are required and both the compilation and execution time for each is greatly reduced. A mutation tool based on the MSG/bytecode translation method has been built and used to measure the speedup over the separate compilation approach. Experimental results show that the MSG/bytecode translation method is about five times faster than separate compilation. Copyright © 2004 John Wiley & Sons, Ltd.     

Model‐based security testing: a taxonomy and systematic classification

Model‐based security testing relies on models to test whether a software system meets its security requirements. It is an active research field of high relevance for industrial applications, with many approaches and notable results published in recent years. This article provides a taxonomy for model‐based security testing approaches. It comprises filter criteria (i.e. model of system security, security model of the environment and explicit test selection criteria) as well as evidence criteria (i.e. maturity of evaluated system, evidence measures and evidence level). The taxonomy is based on a comprehensive analysis of existing classification schemes for model‐based testing and security testing. To demonstrate its adequacy, 119 publications on model‐based security testing are systematically extracted from the five most relevant digital libraries by three researchers and classified according to the defined filter and evidence criteria. On the basis of the classified publications, the article provides an overview of the state of the art in model‐based security testing and discusses promising research directions with regard to security properties, coverage criteria and the feasibility and return on investment of model‐based security testing.
