We mainly use TestRail for test management activities, like creating a test case, logging a defect, assigning to a user story, exporting the test cases, and generating reports.

We use it for test case repository and test management. My primary role is quality assurance. I've got one developer who looks at the SQL, upgrades, and a few other things. I do the customization, integration, and normal administration for granting access. I also provide user support and help users with training, guidance, demos, etc. I handle 80% work, and the developer handles the remaining 20% of work on this solution.

We use TestRail by Gurock as a task management tool. It is integrated with Jira for task tracking.

TestRail is basically a central repository for us since our team is geographically distributed. It is really convenient to use this on cloud. This is one use case. The other is the two-way integration with Jira. That is also one of the important factors.
