• Visual Studio Team System Bugs, test and requirements traceability

  Hi, I'm using VSTS (with both Agile and for CMMi process templates) working primarily on Testing. I have some doubts about traceability of the differents artifacts (requirements, Test Cases and bugs): How can I set this traceability How can I "view" this traceability I started creating a Requirement, a Manual Test and a Bug (created from a failing test execution): I tried linking the Requirement to the Manual Test case using the "versionned item" link type (linking to the last version and to the change set) from the requirement (because I couldn't find a way to link the requirement from the Test).

• SQL Server Task Upgrades, Update and CanUpdate methods.. Why?

  I am writing a new version of a task with and additional property, and wish to support upgrades between the versions. I have implemented the CanUpdate and Update methods, and update the Xml for the new property. The problem I then have it LoadFromXml gets called which promptly fails since it is still using the old version of the Xml. Have I misunderstood the point of the Update mechanism It would seem to me that I’d better off ignoring Update and implementing the checks defaulting my new property within LoadXml. The new version of SaveToXml would sort out the upgrade when saved again. Reviving a thread from the dead. Does anyone hav ...Show All

• Software Development for Windows Vista Questions on workflow types

  Hello,   I have a number of questions about workflow types.   As I understand it, there are two workflow types available out-of-the-box with WWF: sequential and state machine.   With sequential workflows, I believe the flow is generally top down from the initial activity to a final activity.   The path is well defined; activities like ‘While’ allow the workflow to repeat contained activities and the ‘IfElse’ activity allows the workflow author to conditionally execute branches of related activities, which are embedded in the container ‘IfElse’ activity.   In contrast, the state machine workflow is much more adh ...Show All
