Our Test-Script

require 'test_helper'  

class OracleSimpleTest < Test::Unit::TestCase

  def setup
    ActiveRecord::Base.connection.execute "CREATE TABLE DEFAULT_NUMBER (VALUE NUMBER, DATUM DATE DEFAULT sysdate)"
    ActiveRecord::Base.connection.execute "INSERT INTO DEFAULT_NUMBER (VALUE,DATUM) VALUES (0.076,'11.05.09')"
  end

  def teardown
    ActiveRecord::Base.connection.execute "DROP TABLE DEFAULT_NUMBER"
  end


  def test_default_number_precision
    klass = Class.new(ActiveRecord::Base)
    klass.set_table_name "default_number"
    obj = klass.find(:first)
    assert_equal 0.076, obj.value
    assert_not_nil obj.datum, "no date"
  end
end if defined?(JRUBY_VERSION)
