[EditorTest] Running a single edit mode test is really slow

Editor - Other


To reproduce:

1. Open attached project.
2. Open Test Runner.
3. Select an Edit Mode test : CrossSceneReferenceTests -> CrossSceneReferencesShouldStillBePresentAfterSavingScenes
4. Press "Run Selected"

Expected result: Test runs instantly.
Actual result: Editor freezes on main thread for 2-3 seconds before even starting to run the test.

Note: Only happens when there are a lot of tests. On fresh empty project, slowdown is not visible.

Reproducible on: 2017.1.0b1 (a29fc4a7eb25)
Not reproducible: 5.6.0b9 (e1cc23a55ad8)

    It doesn't look like it has been fixed. I am using Unity 2017.1.0f3 and it takes about a minute for the test to even run.

    This was not fixed for the FINAL release of Unity 2017.1 ?! You have been destroying the tests runner performance version after version and didn't find the means to fix it when it was reported in the FIRST beta version of Unity 2017? Really?
