Question

我在lib目录中有一些类，我想测试它。我想测试的课程如下：

class StatAggregation
  class << self
    def skills_rate(user_id)
      user_id = User.find_by_id(user_id)
      ...
    end
  end
end

我创建了规范：

require File.expand_path(File.dirname(__FILE__) + '/../../spec_helper')

describe StatAggregation do
  fixtures [
    :users
  ]

  describe 'skills_rate method' do
    it 'should work' do
      @user_id = 1
      @user = mock_model(User)
      User.should_receive(:find_by_id).with(@user_id).and_return(@user)    
      ...
      StatAggregation.skills_rate(@user_id)
    end
  end
end

它运作正常，但它没有显示出现错误的地方：

1)
ArgumentError in 'PxStatAggregation skills_rate method should work'
wrong number of arguments (1 for 0)
script/spec:10:

Finished in 0.326331 seconds

如何获得出现错误的行数“错误的参数数量（1为0）”？

Answer 1

将-b或--backtrace添加到spec命令行或spec.opts文件。

Rspec和rails：在lib目录中测试库时出现问题
