Regression testing is performed when changes are made to the existing functionality of the software or if there is a bug fix in the software. Regression testing can be achieved through multiple approaches; if a test all approach is followed, it provides certainty that the changes made to the software have not affected the existing functionalities, which are unaltered.
A software performance regression is a situation where the software still functions correctly, but performs more slowly or uses more memory or resources than before. [3] Various types of software regressions have been identified in practice, including the following: [4] Local – a change introduces a new bug in the changed module or component.
Software testing is the act of checking whether software ... Techniques used in white-box testing ... Regression testing focuses on finding defects after a major code ...
Test data are sets of inputs or information used to verify the correctness, performance, and reliability of software systems. Test data encompass various types, such as positive and negative scenarios, edge cases, and realistic user scenarios, and aims to exercise different aspects of the software to uncover bugs and validate its behavior.
Gray-box testing techniques are: Matrix Testing: states the status report of the project. Regression testing: it implies rerunning of the test cases if new changes are made. Pattern Testing: verify the good application for its design or architecture and patterns. Orthogonal array testing: used as subset of all possible combination. [10]
Regression Testing: Orthogonal array testing is effective in the detection of regressions, ensuring that new updates or modifications do not introduce unintended consequences. Configuration Testing : This technique is valuable in assessing different configurations of software, ensuring compatibility across diverse environments.
In software engineering, graphical user interface testing is the process of testing a product's graphical user interface (GUI) to ensure it meets its specifications. This is normally done through the use of a variety of test cases .
In addition, testing of large numbers of users (performance testing and load testing) is typically simulated in software rather than performed in practice. Conversely, graphical user interfaces whose layout changes frequently are very difficult to test automatically. There are test frameworks that can be used for regression testing of user ...
