# are you tired of getting "ignoring attempt to close body with div" warning
# messages in integration and functional testing? do you hate to find where exactly,
# in which otherwise passed assert_select it pops out?
#
# this patch is for you, then!
#
# it makes such a warning fatal, writes current test responce body to a temp file
# and gives you a path for further inspect.
#
# put this in lib/patch_testprocess.rb
# and require it from test/test_helper.rb like this
#
#  require 'lib/patch_testprocess'
#
# please, contact me if it doesn't work for you in some future Rails version,
# or if you make a gem from it or patch rails core, or whatever relevant. thanks
#
# worked for me on Rails2.3.3
