 Assuming developers associate source code with work items on check-in, Team Build has the ability to report on the changes in each build - both source code changes and work item changes as well as test results (this includes unit testing results as well as automated functional testing (CodedUI) results).As bugs and PBIs are resolved and integrated into builds, the work items which track these artifacts are automatically updated to indicate in which build they were successfully integrated.Combined with the testing tools, testers then get an integrated view of what code was changed in each build, but also which bugs, PBIs and other work changed from build to build.
