Let's suppose you have the parser within some kind of class, let's say:

class MyApp::XmlImporter
  def initialize(file)
    @file = file
  end

  def parse
    ...
  end
end

Then add a file to your spec folder spec/lib/my_app/xml_importer_spec.rb:

require 'spec_helper' do

describe MyApp::XmlImporter do
  it "should import the test file" do
    described_class.new("#{Rails.root}/spec/fixtures/test_file.xml").parse

    # Now you check for the correct database state given your test_file.xml
  end
end
