All the expected values should be the same for a top/bottom, left/right arrow,
and none/float pairs, and there are other strong similarities between various
cases. Can you remove some cases or consolidate the tests to avoid some
duplication? Maybe something like this pattern, which I've used with success
elsewhere:

  struct TestCase {
    BubbleBorder::Arrow arrow;
    BubbleBorder::ArrowPaintType paint_arrow;
    gfx::Size content;
    gfx::Size expected;
  };

  const gfx::Size kSmallHorizArrow = ...;
  const gfx::Size kSmallVertArrow = ...;
  const gfx::Size kSmallNoArrow = ...;

  TestCase cases[] = {
     { BubbleBorder::TOP_CENTER, BubbleBorder::PAINT_NORMAL, kSmall,
kSmallHorizArrow },
     { BubbleBorder::TOP_CENTER, BubbleBorder::PAINT_TRANSPARENT, kSmall,
kSmallHorizArrow },
     { BubbleBorder::TOP_CENTER, BubbleBorder::PAINT_NONE, kSmall, kSmallNoArrow
},
     { BubbleBorder::BOTTOM_CENTER, BubbleBorder::PAINT_NORMAL, kSmall,
kSmallHorizArrow },
     { BubbleBorder::BOTTOM_CENTER, BubbleBorder::PAINT_TRANSPARENT, kSmall,
kSmallHorizArrow },
     { BubbleBorder::BOTTOM_CENTER, BubbleBorder::PAINT_NONE, kSmall,
kSmallNoArrow },
     ...
     <Similar cases for vertical arrows, then ditto for all kMedium vert/horiz
cases>
  };

  for(size_t i = 0; i < arraysize(cases); ++i) {
    SCOPED_TRACE(...)
    border.set_arrow(cases[i].arrow);
    border.set_paint_arrow(cases[i].paint_arrow);
    EXPECT_EQ(expected, border.GetSizeForContentsSize(cases[i].content));
  }

[bruthig, 2014/08/20 15:01:28]

Interesting, I stayed away from this approach because I was not familiar with
the SCOPED_TRACE(...) macro and hated how you couldn't tell from the EXPECT_*
output which test actually failed.  This is very useful to know about, thanks!!
:D

[msw, 2014/08/20 20:41:02]

Yeah, SCOPED_TRACE and looping over similar test cases is a great approach, you
can find some examples in RenderTextTest and SearchProviderTest.
