So you have:
    project_dir/
        Rakefile
        tests/
        tests/(lots of tests.rb)
        tests/testdata/

And your current directory when you are running 'rake test' is
project_dir.

The bug is here, the current directory when the test is executed is
'project_dir' but the test assumes it is 'project_dir/tests'

If all of your tests are all in test/ directory the easy way would be to
change your FilePeeker line above to do something like:

    # make sure we have the directory of the data data files, in this
    # case it is relative to the test's directory by being up one and
    # then down the 'testdata' directory
    def setup
        @data_dir = File.join(File.dirname(__FILE__),"..","testdata"))
        ....
    end

    def test_initialize
        o = PAHelper::FilePeeker.new(File.join(@data_dir,'peeker.txt'))
        puts o.output_data
        assert_equal(1, o.output_data.size)
    end

Munge as necessary for deep testing directories, etc.
