测试:通过OS X的单元测试,在CentOS上出错

我有一组针对Rails应用程序的测试::单元测试。它是在OSX上Ruby1.8.6、Rails2.3.4下开发的。

我也在使用thoughtbot shoulda 2.10.2。

我用的是标准的铁轨固定装置,不是工厂。

我已经在CentosLinux5工作站上签出了这个项目,以供其他开发人员使用。他在运行Ruby 1.8.7。

(该应用程序在CentOS Linux 5生产环境下运行,在那里运行良好。)

在我同事的Centos Dev机器上, 单元 测试通过了。

然而,大多数,但不是全部 功能性 测试出错了。我隔离了一个测试(从项目中删除所有其他测试),以缩小故障排除范围。

  context 'on DELETE to :destroy' do
    setup {
      delete(:destroy, { :id => addresses(:mary_publics_address).id }, stans_id)
    }
    should 'delete the address' do
      assert Address.find(:all, :conditions => {
        :id => addresses(:mary_publics_address).id
      } ).blank?
    end
    should 'delete the addresses phone numbers' do
      assert PhoneNumber.find(:all, :conditions => {
        :id => phone_numbers(:mary_publics_phone_number).id
      } ).blank?
    end
  end

我们得到的错误是…

[abc@abc contactdb]$ rake test:functionals --trace

我认为关键的谜团是为什么它找不到 Address 和那个ID.

另一个因素是,当我注释掉这个块时,剩下的测试就通过了。

    should 'delete the addresses phone numbers' do
      assert PhoneNumber.find(:all, :conditions => {
        :id => phone_numbers(:mary_publics_phone_number).id
      } ).blank?
    end

以前有人见过这个吗?

故障排除建议?
