# This module provides some helper methods to assist with fixtures. It's # methods are designed to help when you have a conforming fixture layout so we # get project consistency. module PuppetlabsSpec::Fixtures # Returns the joined path of the global FIXTURE_DIR plus any path given to it def fixtures(*rest) File.join(PuppetlabsSpec::FIXTURE_DIR, *rest) end # Returns the path to your relative fixture dir. So if your spec test is # /spec/unit/facter/foo_spec.rb then your relative dir will be # /spec/fixture/unit/facter/foo def my_fixture_dir callers = caller while line = callers.shift do next unless found = line.match(%r{/spec/(.*)_spec\.rb:}) return fixtures(found[1]) end fail "sorry, I couldn't work out your path from the caller stack!" end # Given a name, returns the full path of a file from your relative fixture # dir as returned by my_fixture_dir. def my_fixture(name) file = File.join(my_fixture_dir, name) unless File.readable? file then fail "fixture '#{name}' for #{my_fixture_dir} is not readable" end return file end # Return the contents of the file using read when given a name.
