nit: Really strange that this test is bundled with UserInputMonitorTest, when
it's actually a unit-test of the KeyboardEventCounter. Also not clear why it is
tied to OS_LINUX || OS_WIN..?

Done.

   KeyboardEventCounter counter;
 
   EXPECT_EQ(0u, counter.GetKeyPressCount());
 
   counter.OnKeyboardEvent(ui::ET_KEY_PRESSED, ui::VKEY_0);
   EXPECT_EQ(1u, counter.GetKeyPressCount());
 
   // Holding the same key without releasing it does not increase the count.
   counter.OnKeyboardEvent(ui::ET_KEY_PRESSED, ui::VKEY_0);
   EXPECT_EQ(1u, counter.GetKeyPressCount());
