Oh, that's a shame. Sure, I'll elaborate.
When I'm going through a fixture full of tests that have gone red, I typically start at the top of my file and work my way down. If I want to check the trace output, or run the test under debugger, or in any way interact with the test in the test window, I naturally click on the test at the top of the list, expecting it to match the test at the top of the file. Even though I know it isn't, I still keep getting tripped up by this. Then I have to search through the list trying to find the right test to select, where often the relevant bit of the test name is at the end of the name and is clipped by the column width. Makes it quite inconvenient.
Also, tests are often (very) loosely grouped together by position in the file. If it's not a strong enough relationship to be worth creating a new fixture for (and breaking the one fixture per class under test convention) then I might have, for example TestAddPerson, TestDeletePerson, TestUpdatePerson method all next to each other, then some other non-Person related tests too.
There's workarounds, I guess, I could rename my tests, or avoid using the test window and use the in-editor popup (for some stuff, other's like the trace output can't be had here), but I find the in-editor UI significantly less convenient than the test window. I think because it's a small target to hit, then a context menu and a new visual search for the UI element to hit and moving the mouse again. Compared to, once the test is selected in the test window, just a single click on the toolbar button that is always in the same place. Really minor stuff, but I think that's why I find it more 'expensive' using the in-editor UI to the test window.
