Marcel Molina, Manik Juneja and DHH
DHH and Marcel were surprised to know that there were Rails programmers in India.

RailsConf2006

VINSOL IS RAILING ....

RailsConf2006 marked the presence of Rails based Indian company Vinsol.
Vinsol's chief Manik Juneja is attending the conference. The 1st day of conference was shining with good sessions by DHH, Marcel, Jamis Buck, Thomas Fuchs and David Black.


There was a very interesting discussion between DHH, Marcel and Jamis Buck about what should go into functional testing and what should go into integration testing.
DHH believes testing for permission should go into integration.

How to prepare test database environment from migrations.

Usually we build our test database by using
$ rake db:test:prepare

To use your migrations for preparing test database create a file testdb.rake
in the directory lib/tasks.
Now add the following code in the lib/tasks/testdb.rake file.

 module Rake
  module TaskManager
    def redefine_task(task_class, args, &block)
      task_name, deps = resolve_args(args)
      task_name = task_class.scope_name(@scope, task_name)
      deps = [deps] unless deps.respond_to?(:to_ary)
      deps = deps.collect {|d| d.to_s }
      task = @tasks[task_name.to_s] = task_class.new(task_name, self)
      task.application = self
      task.add_comment(@last_comment)
      @last_comment = nil
      task.enhance(deps, &block)
      task
    end
  end
  class Task
    class << self
      def redefine_task(args, &block)
        Rake.application.redefine_task(self, args, &block)
      end
    end
  end
end

def redefine_task(args, &block)
  Rake::Task.redefine_task(args, &block)
end

namespace :db do
  namespace :test do

    desc 'Prepare the test database and migrate schema'
    redefine_task :prepare => :environment do
      Rake::Task['db:test:migrate_schema'].invoke
    end

    desc 'Use the migrations to create the test database'
    task :migrate_schema => 'db:test:purge' do
      ActiveRecord::Base.establish_connection(ActiveRecord::Base.configurations['test'])
      ActiveRecord::Migrator.migrate("db/migrate/")
    end
  
  end
end

Now from command prompt run this command to view all the rake tasks
$ rake --tasks

You will c a task as rake db:test:migrate_schema
To prepare the test database run this command
$ rake db:test:migrate_schema
