There are several tools (like burn_in_tests, generated_tasks, etc) that need to understand the membership of resmoke tests and tasks. These tools currently call directly into resmoke code to get this information.

It would be nice, however, to formalize that interface. This would make it easier for other tools take take advantage of it and reduce the coupling between resmoke and the tools mentioned.

This ticket will add a new "discovery" subcommand to resmoke that will provide the various types of test discovery options these commands need.
