Abstract:

This thesis addresses the research in the area of regression testing. Software systems change and evolve over time. Each time a system is changed regression tests have to be run to validate these changes. An important issue in regression testing is how to minimise reuse the existing test cases of original program for modied program. One of the techniques to tackle this issue is called regression test selection technique. The aim of this research is to signicantly reduce the number of test cases that need to be run after changes have been made. Specically, this thesis focuses on developing a mo

This report describes the work on automating the testing of nodes at CCS (Common Control System) in Ericsson. The goal was to every three hours configure nodes with the latest build and run the tests. This process is to be fully automatic without user in-put. The existing configuration tool CICC (Core Integration node Control Center) is to be used for configuration. Before work started fault reports were analyzed and creating a usecase for testing restarts should reduce some faults.The first step was to make the configuration tool CICC automated.

Abstract:

<p>Industrial robots make up an important part in today’s industry and are assigned to a range of different tasks. Needless to say, businesses need to rely on their machine park to function as planned, avoiding stops in production due to machine failures. This is where fault detection methods play a very important part. In this thesis a specific fault detection method based on signal analysis will be considered. When testing a robot for fault(s), a specific test cycle (trajectory) is executed in order to be able to compare test data from different test occasions. Furthermore, different test cy

Abstract:

As Web services grow in maturity and use, so do the methods which are being used to test and maintain them. Regression Testing is a major component of most major testing systems but has only begun to be applied to Web services. The majority of the tools and techniques applying regression test to Web services are focused on test-case generation, thus ignoring the potential savings of regression test selection. Regression test selection optimizes the regression testing process by selecting a subset of all tests, while still maintaining some level of confidence about the system performing no wors

Abstract:

Regression testing is the process of confirming that a code change did not introduce any test failure into the current build. One Regression testing technique commonly used is Regression test selection or RTS. It is the process of identifying all tests affected by a code change, which are identified by creating a dependency graph of the project. The selected tests are then executed. The purpose of RTS is to reduce the development time by lowering the time for testing. Machine learning has been used as a test selection tool in recent studies and have shown promising results.

The main objective of this master thesis is to reconstruct randomized rendered scenarios leading to failure in the 3G system. The incitement is the ability to easily rerun the scenario triggering a failure, take additional traces to isolate the root cause and verify corrections. This is achieved by utilizing CPPemu (Cello Packet Platform) which emulates a complete 3G system, consisting of the RNC (Radio Network Controller), CN (Core Network), RBS (Radio Base Station), UE (User Equipment), where the three latter are simulated by 3Gsim.

Abstract:

Accelerated life tests (ALT) are appealing to practitioners seeking to maximize information gleaned from reliability studies, while navigating resource constraints due to time and specimen costs. A popular approach to accelerated life testing is to design test regimes such that experimental specimens are exposed to variable stress levels across time. Such ALT experiments allow the practitioner to observe lifetime behavior across various stress levels and infer product life at use conditions using a greater number of failures than would otherwise be observed with a constant stress experiment.

In this research, we present an extension to an existing requirement-based regression test suite reduction approach that uses EFSM model dependence analysis to reduce a given regression test suite [19]. The approach is based on the difference between the original model and the modified model expressed as a set of elementary model modifications: elementary addition of a transition and elementary deletion of a transition. For each elementary modification, the data and control dependencies are used to capture potential interactions between EFSM transitions. The potential interactions are used to

Detta görs också med syfte till att kontrollera att systemets befintliga funktioner inte har påverkats negativt av dessa förändringar. Att genomföra regressionstester manuellt är resurskrävande i form av tid och pengar. Därför rekommenderas det att utföra denna aktivitet på ett automatiserat sätt.

Abstract:

Regression analyses constitutes an important part of the statistical inference and has great applications in many areas. In some applications, we strongly believe that the regression function changes monotonically with some or all of the predictor variables in a region of interest. Deriving analyses under such constraints will be an enormous task. In this work, the restricted prediction interval for the mean of the regression function is constructed when two predictors are present. I use a modified likelihood ratio test (LRT) to construct prediction intervals.

The pre-test itself is a test for exact linear restrictions and is conducted using the usual Wald statistic, which provides a Uniformly Most Powerful Invariant test of the restrictions in a well specified model.

Notre travail port sur l'inf´erence au sujet de l'AIC (un cas de vraisemblance p`enalis´ee) d'Akaike (1973), o`u comme estimateur de divergence de Kullback-Leibler est intimement reli´ee `a l'estimateur de maximum de vraisemblance. Comme une partie de la statistique inf´erentielle, dans le contexte de test d'hypoth`ese, la divergence de Kullback-Leibler et le lemme de Neyman-Pearson sont deux concepts fondamentaux. Tous les deux sont au sujet du rapports de 11 vraisemblance. Neyman-Pearson est au sujet du taux d'erreur du test du rapport de vraisemblance et la divergence de Kullback-Leibler es

Abstract:

Software testing is something that is very common and is done to increase the quality of and confidence in a software. In this report, an idea is proposed to create a software for GUI regression testing which uses image recognition to perform steps from test cases. The problem that exists with such a solution is that if a GUI has had changes made to it, then many test cases might break. For this reason, REGTEST was created which is a GUI regression testing tool that is able to handle one type of change that has been made to the GUI component, such as a change in color, shape, location or text.

Soit un modele de regression ou les variables explicatives sont deterministes et les erreurs sont des variables aleatoires independantes gaussiennes centrees. Nous envisageons deux cadres : la regression parametrique non-lineaire et la regression non parametrique monotone. En regression parametrique non-lineaire, nous developpons des resultats asymptotiques au second ordre, l'approche adoptee etant conditionnelle a une statistique ancillaire. Nous etablissons une approximation de type laplace de la densite conditionnelle de l'estimateur du maximum de vraisemblance du parametre de regression. N

Abstract:

Testing is an important activity when developing a system. Testing requires resources in terms of time, labour and money. By correctly automating the tests, the development time may either be shortened or there will be a possibility to run more tests. ABB in Ludvika has developed MACH, a control & protection system for HVDC (high power electrical transmission over long distances) applications. During development of the control & protection system for each HVDC project, which are all unique, the system is today tested manually, which takes considerable time.This thesis project studies t

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV<br>Over the past several years DoD imposed constraints on test deliverables, requiring objective measures of test results, i.e., statistically defensible test and evaluation (SDT&E) methods and results. These constraints force testers to employ statistical hypotheses, analyses and modeling to assess test results objectively, i.e., based on statistical metrics, analytical methods, probability of confi

Abstract:

This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data. The error term in the regression model is assumed to be additive. The main goal of this thesis is to work out diagnostic measures for assessing the influence of observations on various results from a nonlinear regression analysis. The obtained results comprise diagnosti
