A new development project requires the use of the features “Test Management” and “Package Management” which belong to Team Foundation Server 2017. Which licenses do we need to purchase for our developers?

A Team Foundation Server CAL does not suffice to cover those features. Therefore, additional licenses need to be either acquired from the Visual Studio Marketplace or those features can also be covered by a certain Visual Studio license.

To use the feature Test Management you need one of the following:

• a MSDN subscription
• a Visual Studio Enterprise subscription
• a Visual Studio Test Professional subscription
• Test Manager user licenses from the Visual Studio Marketplace

To use the feature Package Management you need one of the following:

• a Visual Studio Enterprise subscription
• Package Management user licenses from the Visual Studio Marketplace
