I would like to request that TestRail support the ability to copy and move Test Runs. The copy feature could include the ability to copy Test Results but we specifically need the ability to copy into a new Test Run (without results).
The copy/move functionality would have to work across Test Plans as well - that is, we should be able to copy or move a Test Run either from the root (outside of a Test Plan) into a Test Plan, from a Test Plan into the root, or from Test Plan to Test Plan.
(Can't think of a business case to copy actual Test Plans but someone might).
Business Cases
The copy functionality will allow us to implement the idea of Test Run templates - rather than re-inventing the wheel (by re-constructing and re-executing filters, which are probably going to become complex) every time we want to do a run, we want to create a base Test Run and copy it into a Test Plan every time we want to execute it.
This would allow us to create a template for different Regression Test Runs that could be used across multiple releases, or create Feature Test Run templates for use across multiple cycles in a single release.
The move functionality will enable us to move a Test Run, which may have been created for the purpose of a feature set that was targeted for release A, from a Test Plan that was created for release A into a Test Plan for release B if necessary.
