--- title: VS402325 Work item type category Microsoft.TestPlanCategory does not exist in project layout: post.liquid published_date: 2015-11-04 15:00:00 -0800 --- I tried to create a Test Plan on our Team Foundation Server today but I got this error message: VS402325: Work item type category Microsoft.TestPlanCategory does not exist in project xxx I solved this this by following the directions in this [MSDN article] to enable the Test Plan feature on the project. There were no search results at the time of writing about this error message, I thought I may as well post one.
