nit: using ContentSettingBubbleContentsTest = views::ViewsTestBase;

[Charlie Harrison, 2017/04/11 19:20:57]

Done.

q: Hmm, should this be bubble_view->GetWidget()->GetNativeView()?

[Charlie Harrison, 2017/04/11 19:20:57]

I think it needs to be bubble_view->GetWidget()->GetNativeWindow(), no? The
constructor takes a native window, not a native view.

[msw, 2017/04/11 19:27:35]

Yup, typo on my part; just meant s/widget/bubble_view->GetWidget()/

+      event_generator.MoveMouseTo(checkbox->GetBoundsInScreen().CenterPoint());
+      event_generator.ClickLeftButton();
+
+      EXPECT_TRUE(checkbox->checked());
+      break;
+    }
+  }
+
+  // The done button's text and size should change.
+  EXPECT_EQ(done_button_text, button->GetText());
+  EXPECT_GT(button->width(), before_width);
+
+  widget->Close();
+}
