Change Impact Analysis Based Regression Testing of Web Services

Reducing the effort required to make changes in web services is one of the primary goals in web service projects maintenance and evolution. Normally, functional and non-functional testing of a web service is performed by testing the operations specified in its WSDL. The regression testing is performed by identifying the changes made thereafter to the web service code and the WSDL. In this thesis, we present a tool-supported approach to perform efficient regression testing of web services. By representing a web service as a directed graph of WSDL elements, we identify and gathers the changed portions of the graph and use this information to reduce regression testing efforts. Specifically, we identify, categorize, and capture the web service testing needs in two different ways, namely, Operationalized Regression Testing of Web Service (ORTWS) and Parameterized Regression Testing of Web Service (PRTWS). Both of the approach can be combined to reduce the regression testing efforts in the web service project. The proposed approach is prototyped as a tool, named as Automatic Web Service Change Management (AWSCM), which helps in selecting the relevant test cases to construct reduced test suite from the old test suite. We present few case studies on different web service projects to demonstrate the applicability of the proposed tool. The reduction in the effort for regression testing of web service is also estimated.Comment: Master of Technology Thesis, PDPM Indian Institute of Information Technology, Design and Manufacturing Jabalpur (2014

Preemptive regression test scheduling strategies: a new testing approach to thriving on the volatile service environments

A workflow-based web service may use ultra-late binding to invoke external web services to concretize its implementation at run time. Nonetheless, such external services or the availability of recently used external services may evolve without prior notification, dynamically triggering the workflow-based service to bind to new replacement external services to continue the current execution. Any integration mismatch may cause a failure. In this paper, we propose Preemptive Regression Testing (PRT), a novel testing approach that addresses this adaptive issue. Whenever such a late-change on the service under regression test is detected, PRT preempts the currently executed regression test suite, searches for additional test cases as fixes, runs these fixes, and then resumes the execution of the regression test suite from the preemption point. © 2012 IEEE |postprin

(Why) Is My Prompt Getting Worse? Rethinking Regression Testing for Evolving LLM APIs

Large Language Models (LLMs) are increasingly integrated into software applications. Downstream application developers often access LLMs through APIs provided as a service. However, LLM APIs are often updated silently and scheduled to be deprecated, forcing users to continuously adapt to evolving models. This can cause performance regression and affect prompt design choices, as evidenced by our case study on toxicity detection. Based on our case study, we emphasize the need for and re-examine the concept of regression testing for evolving LLM APIs. We argue that regression testing LLMs requires fundamental changes to traditional testing approaches, due to different correctness notions, prompting brittleness, and non-determinism in LLM APIs.Comment: conference versio

ABSTRACT PURWO ERIE NASTITI. The influence of tax service toward taxpayers compliance land value tax in RW 01 Kelurahan South Gandaria (comparison study between compliant and delinquent taxpayers). Thesis. Jakarta: Economics Education Studies Program, Concentration in Economics Cooperative Education, Department of Economics and Administration, Faculty of Economics, State University of Jakarta. July. 2012. This study aims to determine whether there is influence between service of Taxation toward tax Compliance either the compliant taxpayers or taxpayer who delinquent tax. The study was conducted over 3 (two) months from May to July 2012. The method used is survey method with the correlational approach. The study population was at the land value tax Taxpayer RW 01-abiding and delinquent taxpayers. Researchers took 20% of the population-abiding taxpayers and 10% of the population of delinquent taxpayers To collect data from the two variables of the study, the research instruments used for the variable X (service tax) and the variable Y (taxpayer compliance) is the form of a questionnaire. Prior to use, construct validity tested through the validation process is the calculation of the correlation coefficient score points with the total score and reliability testing with Cronbach Alpha formula. The results of the reliability of the instrument variable X (service tax) for 0845. while for the variable Y (taxpayer compliance) for 0.818. For taxpayers who are obedient, test requirement analysis is done by finding the regression equation obtained was Y = 85.18 + 0211. lilifors normality test results produced Lcount = 1.54 while for n = 30 Ltabel the significance level (a = 0.05) is 0161. Because Laccount <Ltabel the variables X and Y are normally distributed. Testing the hypothesis by generating regression test Fcount (9:49)> Ftabel (4.20) which berrati significant regression coefficients. Testing linearity of regression produces Fcount (-1.33) tTable (1.72). To a delinquent taxpayer, the test requirements analysis is performed by finding the regression equation, the results obtained is Y = 42.70 + X. 0428 lilifors normality test results produced Lcount = 1.53 while for n = 30 Ltable the significance level (a = 0.05) is 0161. Because Lcount Ftable (4.20) which means a significant regression coefficient. Testing linearity of regression produces Fcount (2.11) <Ftable (2.42) thus concluded that the linear regression equation. Product moment correlation coefficient test result rcount = 0.33. significance test is then performed regression correlation coefficient using t test, produce tcount (1.87)> TTable (1.72). The results of these studies concluded that there was a positive influence on adherence between the tax service for taxpayer-abiding taxpayers and delinquent taxpayers. For taxpayers who obey the coefficient of determination test results obtained 22.31%, taxpayer compliance variable (Y) is determined by the tax service (X). As for the delinquent taxpayer that the coefficient of determination of test results obtained 11.15% taxpayer compliance variable (Y) is determined by the tax service (X) Key words: tax services, Taxpayer Complianc
