Manual testing is a process in software development where testers manually execute test cases without the use of automated tools. This method involves a tester playing the role of an end user and using most of the application's features to ensure correct behaviour. The primary goal of manual testing is to identify bugs, issues, and defects in the software application. It is a fundamental aspect of quality assurance and is crucial for ensuring that the software meets the specified requirements and functions as expected.

In the context of Digital Asset Management (DAM) systems like ResourceSpace, manual testing is essential for verifying that the system can handle various types of digital assets, such as images, videos, and documents, effectively. Testers would manually upload, search, retrieve, and manage these assets to ensure that the system's functionalities are working correctly. This includes checking the user interface for usability, ensuring that metadata is correctly applied and searchable, and verifying that permissions and access controls are functioning as intended. Manual testing in DAM systems helps in identifying user experience issues that automated tests might overlook.

One of the significant advantages of manual testing is its ability to provide human insight and intuition, which can be particularly valuable in identifying user interface and user experience issues. Testers can provide feedback on the look and feel of the application, which is crucial for applications like ResourceSpace that are heavily used by creative professionals. Manual testing also allows for more flexible and exploratory testing, where testers can deviate from predefined test cases to explore potential edge cases and unexpected behaviours.

However, manual testing can be time-consuming and may not be as efficient for repetitive tasks compared to automated testing. It requires a significant amount of human resources and can be prone to human error. Despite these drawbacks, manual testing remains an indispensable part of the software development lifecycle, especially in the initial stages of development and for applications that require a high degree of user interaction and visual assessment, such as Digital Asset Management systems.
