Regression testing is a crucial software testing process aimed at verifying that previously developed and tested software continues to perform as expected after changes are made. It should be conducted whenever new features are added, existing functionalities are modified, or new integrations are performed. The document outlines the phases of regression testing, including need identification, test case definition, and the use of manual or automated testing methods, emphasizing the importance of careful planning and execution.

TestingXperts Delivers a spectrum of Regression testing services such as: According to Wikipedia, Regression testing is an important type of software testing that revolves around re-running functional and non-functional tests. These tests are conducted to ensure and check the previously developed and tested software still performs well even after a change is made in the software. Primarily, it checks whether the previous functionality of an application is working as intended even with a new feature added. It checks for any new bug or error in the existing software and is a verification process that takes place in the software. Whenever a new feature is developed, or when an existing feature is improved or if there are any UI updates made, eventually there is a need to perform software regression testing. Functional and regression testing should be performed to ensure that the changes do not impact the already existing functionality of the software. In addition, the regression testing process should be employed whether there is a small localized change to the software or for even a larger change that might affect any change to the old functionality. Functional regression testing teams must verify that the new code does not conflict with older code, and also confirms that the code that has not been changed is still working as expected. Therefore, this type of visual regression testing ensures that the previous functionality of the application works effectively and new changes have not introduced any sort of new bugs within the application. A change is the key concept of regression testing process to take off and it should be taken up when: New functionality is taken up It is one of the important stages to initiate the regression testing process. Whenever the developers introduce new code, they don’t fully concentrate on its compatibility with the existing code and hence the software regression testing should be taken up to find any possible issues within software. Existing functionality changes Within the software development process, in some cases, developers revise the existing functionality and exclude or edit some features based on the requirements. In such cases, functionality and regression testing process checks whether the new changes or features do not cause any damage to the rest of the functionality. New Integrations take place with other products At times of integration, regression testing assures that the software product performs flawlessly even after integration with another product. Define & Identify Needs and Components of Initial Phase This is the first and important step to start with the software regression testing process wherein the moment a single change takes place within the software, regression tests should ideally be initiated. The main motive is to test the existing code or functionality with the help of regression test scripts. Therefore, careful planning should be taken up to identify the needs and components of regression testing. Define Testing Requirements This is the second phase wherein defining of the right test cases for a project should be taken up. This phase is achieved with an effective collaborative approach established between stakeholders, developers, and software test engineers. Therefore, a common consensus is required to decide upon the test cases that need to be prepared which could be reused each time there is a change in the application. Define Entry & Exit Criteria There is an effective need to define the entry and exit points of regression testing such that the test objectives are in sync with the project requirements. Before beginning the software regression testing, the entry and exit criteria should be identified to smoothen the process of regression testing. Regression testing can be achieved by adopting either manual regression testing or automated regression testing. What is Manual Regression testing? When regression testing is performed by manual testers, then test cases are initially drafted and they will be executed. These tests help to check whether it is a pass or fail based on the expected results mentioned in the test cases. No separate tools are used to perform this testing process. What is Automated Regression Testing? When it comes to automated regression testing, various types of test automation tools are used to perform the regression testing process. It is evident that manual regression testing takes a lot of time and to save time, automated regression testing is taken up. Typically, automated regression testing includes various steps such as deciding on what test cases to automate, whether to test early or test often, along with some importance placed around test automation tool to be selected.
