What exclamation mark means near the play test icon in front of class name. Espresso. Testing

Issue

I write automated tests in Espresso for Android and i was faced with next problem.

I noitced the exclamation mark near the play icon in front of class name that we usually use for launch all tests of some class by one click.

Please take a look a picture:

I have to note that i don't get any errors, all my UI tests launch without problem.

Did i miss something? Or that exclamation mark does not have any relation with testing?

Thanks all!

Solution

You should be able to see all the Android Studio "Gutter Icons" in preferences.

Preferences > Editor > General > Gutter Icons (Mac, Android Studio 3.3.2)
