noun the process of retesting a software application after changes have been made to ensure that the existing functionality still works correctly
In software development, regression testing is used to ensure that new code changes do not adversely affect existing functionality.
In quality assurance, regression testing is used to verify that previously fixed bugs have not reappeared in the software.
In DevOps practices, regression testing is integrated into the deployment process to prevent unexpected issues in production environments.
In CI/CD pipelines, regression testing is often automated to quickly detect any regressions introduced by new code changes.
In Agile development methodologies, regression testing is performed frequently to maintain the stability of the software.
In the field of technical writing, regression testing is often used to ensure that software documentation remains accurate and up-to-date after changes have been made to the software. Writers may also use regression testing to verify that user guides and manuals are still relevant and effective.
Psychologists may use regression testing in research studies to validate the results of previous experiments or to ensure the reliability of psychological assessments. By retesting subjects with the same measures, psychologists can confirm the consistency and stability of their findings.
Software developers commonly use regression testing to verify that new code changes do not introduce bugs or errors into existing software systems. By running automated tests on a regular basis, developers can quickly identify and fix any regressions that occur during the development process.
Quality assurance testers rely on regression testing to confirm that software updates or modifications do not negatively impact the overall functionality of an application. By conducting thorough regression tests, QA testers can ensure that all features continue to work as intended across different platforms and devices.
Project managers may use regression testing to track the progress of software development projects and ensure that deadlines are met. By monitoring the results of regression tests, project managers can identify any potential roadblocks or delays in the development process and take corrective action as needed.
