I can't make ViewActions.closeSoftKeyboard() work in Espresso 2.2.2

I'm trying to test an app and I require to hide the keyboard, because I cannot click button because of it. So, I added Espresso in build.gradle:

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'

and tried to use this from android.support.test.espresso.action.ViewActions library:

ViewActions.closeSoftKeyboard();

Test runs successfully, but fails after typing some text in EditText in my layout. And keyboard is still there, showing.

P.S. I realized it was keyboard's fault after reading this answer.
