Comment 1 for bug 807873

This is a known problem with NUnit 2.x, which requires significant design changes in order to fix. For that reason, it has been scheduled for correction in the NUnit 3.0 project.

Under NUnit 2.x, the Gui display is not separate from the structure of the tests themselves. That is, when you select a flat list, the tests are loaded by the nunit core without the hierarchical information that is needed to run the SetUpFixtures for a given namespace. In the NUnit 3.0 design, the structure shown in the Gui is entirely separate from the actual structure of the loaded tests.

(Changed the title so it fits with 3.0 as well as 2.x.)
