A gist for adding a CI rake task for project hydra applications so that Jetty gets started and stopped between test runs, this code should guarantee that Solr is up before starting your rspec or cucumber tests.

Rakefile

require 'jettywrapper'
require 'rsolr'

desc 'Start up jetty and run rspec and cucumber tests'
task :ci => ['jetty:unzip', 'jetty:config'] do
  puts 'running continuous integration'
  jetty_params = Jettywrapper.load_config
  error = Jettywrapper.wrap(jetty_params) do
    ping_solr #check solr is up before starting the tests
    Rake::Task['spec'].invoke
    Rake::Task['cucumber'].invoke
  end
  raise "test failures: #{error}" if error
end

#Because Jetty takes a long time to start Solr and Fedora we need to wait for it before starting the tests
#Following code attempts to connect to Solr and run a simple query, if the connection refused it catches
#this error and sleeps for 5 seconds before trying again until successful
def ping_solr
  begin
    solr = RSolr.connect :url => 'http://localhost:8983/solr'
    response = solr.get 'select', :params => {:q => '*:*'}
    puts 'Solr is up!'
    return
  rescue Errno::ECONNREFUSED
    puts 'Solr not up yet, sleeping for 10 seconds... zzz'
    sleep 10
    ping_solr
  end
end
