Model-based regression testing of web services Information technology essay
Regression testing is an essential activity to ensure that changes to the software code do not adversely affect existing functionalities. With the widespread adoption of Continuous Integration CI in software projects increasing the frequency of executing software builds, running all the tests can be time-consuming and labor-intensive.

Group testing has been verified as a cost-effective and time-efficient approach, pooling the individual samples with a predefined group size for subsequent testing. Recent research has explored the integration of covariate information to improve the modeling of group test data. While the existing works for high numbers, an overview of common machine learning algorithms used for regression problems. 1. Linear regression. As the name suggests, linear regression attempts to capture the linear relationship between the predictive set of input variables and the variable we want to predict. Create a folder under your C:\Inetpub\www.root called WebServices wwroot image Then go ahead and copy the following code into Notepad: Basically, the first line says that this is a web service and the language used is C. Next we import two namespaces, System and System. Web. Services. Regression testing is the process of testing the changed parts of the code and the parts that may be affected by the changes to ensure that no new bugs have been introduced into the software after the changes have been made. Regression means the return of something and in software terms it refers to the return of a bug. Running the test for the second version of the web app looks like this: As a result, the second test fails due to the missing attr attribute. Automate regression testing to increase quality. Component-based software development has become increasingly popular in recent decades. Currently, component delivery only includes interface specifications, which complicates selection and integration. Web services and their underlying system grow over time and need to be retested whenever a change occurs. This is essential to ensure uncompromising quality. If we have only modified a small part of the system, it should be possible to reuse the existing test suite. Anyway, for major changes or for large systems, regression testing is performed by identifying the subsequent changes made to the web service code and the WSDL. In this thesis we present a tool-supported approach to perform efficiently. One of the most important techniques, Regression Test Selection RTS, aims to reduce the cost of performing RT. This paper reports a control flow graph-based approach that makes this possible. These tools help a lot by running tests quickly and saving a huge amount of time for testers. gt Click,
