Editor Test Runner: Collapse All?

In the asset version of Unity Test Tools there was an option to collapse all tests.

Unity recently integrated the unit test portion of the Test Tools directly into Unity through the Editor Test Runner, removing unit testing from the asset store version.

In the old version you could right click on the test runner to "collapse all." This was very useful for when you have many tests expanded and want to quickly close all of them.

I can't find this feature in the new version.

I've attached a picture of where this option used to be.

 

I know this is a old thread but the good old "hold the alt button" works on this window also

 

Thanks so much for that tip. I never knew that I could hold down alt
