app/models/part.rb

class Part < ActiveRecord::Base
  def after_create
    raise "no way" if self.name == "test"
  end
end

app/controllers/parts_controller.rb

class PartsController < ApplicationController
  def test
    Part.create!(:name => "test")
  end
end

test/functional/parts_controller_test.rb

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

class PartsControllerTest < ActionController::TestCase
  def test_test
    old_count = Part.count
    post :test rescue nil   
    assert_equal(old_count, Part.count)
  end
end

    ruby test\functional\parts_controller_test.rb

结果是

<2> expected but was
<3>.

日志是

Processing PartsController#test (for 0.0.0.0 at 2008-05-01 16:26:57) [POST]
  Session ID: 
  Parameters: {"action"=>"test", "controller"=>"parts"}
  Part Create (0.000000)   INSERT INTO parts ("name", "updated_at", "created_at") VALUES('test', '2008-05-01 16:26:57', '2008-05-01 16:26:57')
  SQL (0.000000)   SELECT count(*) AS count_all FROM parts 

看到没. 居然没有 回滚

换用集成测试
test/integration/model_hg_test.rb

require "#{File.dirname(__FILE__)}/../test_helper"

class ModelHgTest < ActionController::IntegrationTest
  fixtures :parts

  def test_truth
    old_count = Part.count
    
    puts Part.find_by_sql("select * from parts").collect(&:id).join(", ")
    puts Part.find_by_sql("select * from parts").collect(&:name).join(", ")
    
    post '/parts/test'
    
    puts Part.find_by_sql("select * from parts").collect(&:id).join(", ")
    puts Part.find_by_sql("select * from parts").collect(&:name).join(", ")
    
    assert_equal(old_count, Part.count)
    
  end
end

结果是
