I don't think you need the "<< web_event.domKey" or on the line below. EXPECT_EQ
will generate the sufficient info if it doesn't match.

+    EXPECT_EQ(ui::VKEY_APPS, web_event.windowsKeyCode)
+        << web_event.windowsKeyCode;
+  }
+}

 // Flaky - https://crbug.com/640457
 // Test that a ui::Event and blink::WebInputEvent made from the same NSEvent
 // have the same values for comparable fields.
