After installing the Test Management plugin, which role is required for a user to use it?

The role Tm_test_manager is specifically designed for users who need to manage testing activities within the Test Management plugin in ServiceNow. This role grants the necessary permissions required to oversee the test management processes, including creating, executing, and managing test cases and instances.

Having the right role is crucial in ServiceNow, as it helps to ensure that only authorized users can perform specific actions related to test management. This also aids in maintaining the integrity of the test management process by restricting access to sensitive functionalities.

The other roles, while they may provide some level of access to test management features, do not encompass the full range of capabilities required to effectively manage the entire testing lifecycle. Thus, for comprehensive management of testing activities, the Tm_test_manager role is essential and appropriate.
