Test Plans are a new way to manage which tests run, and how those tests run. Schemes can reference multiple test plans, and define a default test plan for automation. A new Test Plan editor supports defining test configurations, which can inherit shared settings from the plan itself. Running tests in Xcode now runs tests across all test configurations. The Source Editor test diamonds are updated to support running a test in a single configuration, and the Test Navigator is updated to allow choosing the active test plan. Test reports are updated to support displaying results generated by a test plan. (16138582)
