Establishing structural testing criteria for Java bytecode

This paper describes intra‐method control‐flow and data‐flow testing criteria for the Java bytecode language. Six testing criteria are considered for the generation of testing requirements: four control‐flow and two data‐flow based. The main reason to work at a lower level is that, even when there is no source code, structural testing requirements can still be derived and used to assess the quality of a given test set. It can be used, for instance, to perform structural testing on third‐party Java components. In addition, the bytecode can be seen as an intermediate language, so the analysis performed at this level can be mapped back to the original high‐level language that generated the bytecode. To support the application of the testing criteria, we have implemented a tool named JaBUTi (Java Bytecode Understanding and Testing). JaBUTi is used to illustrate the application of the ideas developed in this paper. Copyright © 2006 John Wiley & Sons, Ltd.

Anomaly detection in performance regression testing by transaction profile estimation

As part of the process to test a new release of an application, the performance testing team need to confirm that the existing functionalities do not perform worse than those in the previous release, a problem known as performance regression anomaly. Most existing approaches to analyse performance regression testing data vary according to the applied workload, which usually leads to the need for an extra performance testing run. To ease such lengthy tasks, we propose a new workload‐independent, automated technique to detect anomalies in performance regression testing data using the concept known as transaction profile (TP). The TP is inferred from the performance regression testing data along with the queueing network model of the testing system. Based on a case study conducted against two web applications, one open source and one industrial, we have been able to automatically generate the ‘TP run report’ and verify that it can be used to uncover performance regression anomalies caused by software updates. In particular, the report helped us to isolate the real anomaly issues from those caused by workload changes with an average F1 measure of 85% for the open source application and 90% for the industrial application. Such results support our proposal to use the TP as a more efficient technique in identifying performance regression anomalies than the state of the art industry and research techniques.

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.     

Understanding the effects of changes on the cost‐effectiveness of regression testing techniques

Regression testing is an expensive testing process used to validate modified software. Regression test selection and test‐case prioritization can reduce the costs of regression testing by selecting a subset of test cases for execution, or scheduling test cases to meet testing objectives better. The cost‐effectiveness of these techniques can vary widely, however, and one cause of this variance is the type and magnitude of changes made in producing a new software version. Engineers unaware of the causes and effects of this variance can make poor choices in designing change integration processes, selecting inappropriate regression testing techniques, designing excessively expensive regression test suites and making unnecessarily costly changes. Engineers aware of causal factors can perform regression testing more cost‐effectively. This article reports the results of an embedded multiple case study investigating the modifications made in the evolution of four software systems and their impact on regression testing techniques. The results of this study expose tradeoffs and constraints that affect the success of techniques and provide guidelines for designing and managing regression testing processes.
