Test result data retention with Team Foundation Server 2015

This post introduces test result data cleanup capabilities in TFS 2015 Update 1. It enables deleting test results when builds are deleted (for Build vNext) and cleaning up test results based on age at the team project level. This includes team project-level retention policies for automated and manual test results, and build vNext-level policies to delete test results when builds are deleted. These features aim to keep test systems performant and responsive by periodically cleaning up irrelevant test data.
