This behavior is only tangentially related to IME (i.e., cut/copy/paste commands
are simply forwarded by ImeAdapter.java, they don't meaningfully interact with
the adapter). 

I think you can test this functionality using minimal interaction with IME
itself, e.g., you can programatically add text to the clipboard: 

 ClipboardManager clipboard = (ClipboardManager)
getSystemService(CLIPBOARD_SERVICE); 
 ClipData clip = ClipData.newPlainText("test", "Text to copy");
 clipboard.setPrimaryClip(clip);

then you can avoid the boilerplate of commit/selectall/cut on these tests.  With
that, I would move all of these tests to ContentViewCoreSelectionTest.java.

Thanks for the suggestion, I had corrected it and moved to
ContentViewCoreSelectionTest.java.
