This is being moved to the spellcheck-specific test.

-      test('spellcheck edit dictionary page add word validation', function() {
-        assertFalse(!!languagesPage.$$('settings-edit-dictionary-page'));
-        var spellCheckCollapse = languagesPage.$.spellCheckCollapse;
-        MockInteractions.tap(
-            spellCheckCollapse.querySelector('.list-button'));
-        var editDictPage = languagesPage.$$('settings-edit-dictionary-page');
-        assertTrue(!!editDictPage);
-        var addWordButton = editDictPage.root.querySelector('paper-button');
-        editDictPage.$.newWord.value = '';
-        assertTrue(!!addWordButton);
-        assertTrue(addWordButton.disabled);
-        editDictPage.$.newWord.value = 'valid word';
-        assertFalse(addWordButton.disabled);
-      });
-    }
   }.bind(this));
