Perhaps we shouldn't even test this, then?  I can see future people
wanting to change this behaviour, while I can see argument for not
touching the working tree file, too.  It is essential for the main
purpose of the command (i.e. "I want to flip the executable bit for
the path in the index") to make sure that the bit in the index is
changed.  Comparing the index with the working tree using "status"
is probably not how you would want to do so.  A future breakage may
cause the indexed blob name to change by mistake, and status would
happily report difference but you would not notice its output is
saying "Hey, they are different between the index and the working
tree", while you are expecting ONLY the change in the executable bit.

How about doing

        git add foo4 &&
        git add --chmod=+x foo4 &&
        test_mode_in_index 100755 foo4
