Ultrasphinx setup part2

Regarding what I wrote about test database in section "4. Build index" in my previous post "Ultrasphinx setup", RSpec code would become like below.

I put this under spec/models accessing database. But for controller spec under spec/controllers, I mocked Ultrasphinx::Search so that the controller spec is not accessing database.

(Note: The line with "system(..)" is one line.
It is shown to be multiple lines because of the space.)

require File.dirname(__FILE__) + '/../spec_helper'

describe "Ultrasphinx sample" do
  fixtures :overviews

  before(:each) do
    system("cd #{RAILS_ROOT}; 
      rake ultrasphinx:index RAILS_ENV=\"test\"")
    system("cd #{RAILS_ROOT};
      rake ultrasphinx:daemon:start RAILS_ENV=\"test\"
        &> /dev/null")
  end

  after(:each) do
    system("cd #{RAILS_ROOT};
      rake ultrasphinx:daemon:stop RAILS_ENV=\"test\"
        &> /dev/null")
  end

  it "should find text with 'test'" do

    @search = Ultrasphinx::Search.new(:query => "test")
    @search.run

    @search.results.size.should == 2

  end

end
