nit: No need to test the y co-ordinate.

+  EXPECT_EQ(67, ([cell imageRectForBounds:rect]).origin.x);

[Ilya Sherman, 2011/12/14 00:27:39]

Rather than testing that the x-coordinate is 55 or 67, please test that the
x-coordinate is different depending on whether a title is set for |cell|; and
that it is the same regardless of whether a title is set for |folder_cell|.

[KushalP, 2011/12/14 00:31:04]

So something like:

EXPECT_NE(67, ([cell imageRectForBounds:rect]).origin.x);

?

[Ilya Sherman, 2011/12/14 00:33:06]

Something like:

[cell setBookmarkCellText:@"" image:image];
int x_without_title = [cell imageRectForBounds:rect]).origin.x;
[cell setBookmarkCellText:@"test" image:image];
int x_with_title = [cell imageRectForBounds:rect]).origin.x;
EXPECT_NE(x_without_title, x_with_title);

(Except "int" is probably the wrong integer type for the coordinate.)
