Regression testing is a crucial process in software development and maintenance, particularly within the context of Digital Asset Management (DAM) systems like ResourceSpace. It involves re-running previously completed tests on a modified software application to ensure that recent changes have not adversely affected existing functionality. This type of testing is essential for maintaining the integrity and performance of the software, especially after updates, bug fixes, or enhancements have been implemented.

In the realm of Digital Asset Management, regression testing ensures that new features or updates do not disrupt the system's ability to manage, store, and retrieve digital assets efficiently. For instance, if a new feature is added to improve metadata tagging, regression testing would verify that this addition does not interfere with existing functionalities such as asset search, user permissions, or file uploads. This is particularly important in DAM systems where the seamless operation of various integrated components is critical for user satisfaction and operational efficiency.

The process of regression testing can be automated or manual. Automated regression testing is often preferred in complex systems like ResourceSpace due to its efficiency and ability to quickly execute a large number of test cases. Automated tools can be programmed to run tests at scheduled intervals or in response to specific events, such as code commits. This ensures that any issues are identified and addressed promptly, reducing the risk of downtime or user disruption.

Manual regression testing, on the other hand, involves human testers who execute test cases and verify outcomes. While more time-consuming, manual testing can be beneficial for identifying issues that automated tests might miss, such as user interface inconsistencies or unexpected user behaviour. In a DAM system, both automated and manual regression testing play complementary roles in ensuring that the software remains robust, reliable, and user-friendly, even as it evolves to meet new requirements and challenges.
