rails--rails/activesupport/lib/active_support/testing/file_fixtures.rb
Yves Senn d28e5b94a7 introduce ActiveSupport::Testing::FileFixtures.
It's a thin layer to provide easy access to sample files throughout
test-cases. This adds the directory `test/fixtures/files` to newly
generated applications.

# Adds simple access to sample files called file fixtures.
# File fixtures are normal files stored in
# <tt>ActiveSupport::TestCase.file_fixture_path</tt>.
#
# File fixtures are represented as +Pathname+ objects.
# This makes it easy to extract specific information:
#
# file_fixture("example.txt").read # get the file's content
# file_fixture("example.mp3").size # get the file size

#
# Raises ArgumentError if +fixture_name+ can't be found.
