Rspec 使用未定义变量测试复杂代码

Question

在 rspec 测试方面只需要一点帮助...对它很陌生，不太知道如何测试这段代码

# Get a list of tasks recently used by the user
    recent_task_ids = Effort.all( :select => "project_task_id",
                                  :conditions => { :user_id => @user_id },
                                  :group => "project_task_id",
                                  :order => "MAX( week_commencing )" )


    # For each of the task ids, get the actual project task records
    @recent_tasks = []
    recent_task_ids.each do |effort|
      if ProjectTask.find_by_id( effort.project_task_id ) != nil
        @recent_tasks.push( ProjectTask.find( effort.project_task_id ) )
      end
    end

不确定您是否应该以这种方式测试未定义的变量，但任何帮助都会很棒

Answer 1

您可以删除 Effort.all 方法。

it "tests with nil values" do
  Effort.stub(:all).and_return(nil)
end
