rubygem-escape_utils (not yet in Fedora) was also converted upstream
to Minitest 5. Here's what I used in %prep to switch back to the old
Minitest 4 syntax:

# Get the major version number of the Minitest gem
minitest=$(ruby -r 'minitest/unit' \
  -e "puts Minitest::Unit::VERSION.split('.')[0]")
if [ $minitest > 5 ]; then
  # Conditionally correct Minitest usage, for Minitest versions < 5.0.0.
  # For example, at least Fedora 20 has Minitest 4.x.
  for f in $(find test -type f); do
    sed -i "s/Minitest::Test/Minitest::Unit::TestCase/g" $f
  done
fi

This should be forward-compatible with Minitest 5 when it lands in Fedora 21.
