Better Jasmine rake task. Starts the server and opens it in the default browser.

jasmine.rake

begin
  require 'jasmine'
  load 'jasmine/tasks/jasmine.rake'
  
  namespace :jasmine do
    task :server_without_open => :server
    
    desc 'Run specs via server'
    task :server_with_open do
      Rake::Task['jasmine:server_without_open'].invoke
      
      Thread.new do
        sleep 1
        `open http://localhost:8888`
      end
    end
    
    remove_task :server
    task :server => :server_with_open
  end
rescue LoadError
  puts 'Jasmine gem not available.'
end

remove_task.rake

Rake::TaskManager.class_eval do
  def remove_task(task_name)
    @tasks.delete(task_name.to_s)

def remove_task(task_name)
