TFS has several built-in reports readily available for the selected process template. Some of these reports are specific to defects, and some are specific to testing while some others are common to work items.
Bugs are the list of defects found during the test run or code compilation, or during the build, or an exception during the test. All these defects can be added as work items of type Bug to the team project under the TFS. There are different parameters to the work item such as the iteration, area, priority, triage, description, title, and other additional details for the defect. Every time the defect is modified, a history is maintained. The first time the defect is added, the status would be active. Whenever the defect is fixed, the developer can change the status to resolve so that the tester can test the defect in the next deployment of the application and change it to fixed. All these activities are tracked, and history is maintained in the SQL Server...
