RSPEC如何發佈到控制器？這有什麼問題？

Question

我想發佈到我的控制器在RSPEC，看到有什麼不對？它的失敗W/O錯誤：

it "should store create an IncomingMail record" do 
    lambda {  
    post 'create', { 
      "from" => 'XXX', 
      "to" => 'XXX', 
      "cc" => 'XXX', 
      "subject" => 'XXX', 
      "message_text" => 'XXX', 
      "message_html" => 'XXX' } 
    }.should change { IncomingMail.count }.by(1) 
end 

更新時間：

it "should store create an IncomingMail record" do 
    post :create, 
     :from => 'xx', 
     :to => 'xx', 
     :cc => 'xx', 
     :subject => 'xx', 
     :message_text => 'xx', 
     :message_html => 'xx' 

    mail = IncomingMail.last(:order => 'created_at desc') 
    mail.from.should == 'xx' 
end 

控制器

class IncomingMailsController < ApplicationController 

    require 'iconv' 

    #make sure that rails doesn't raise an exception because we have no way of knowing the token 
    skip_before_filter :verify_authenticity_token 

    def create 

    begin 
     @incoming_mail = IncomingMail.create(
              :from => params[:from], 
              :to => params[:to], 
              :cc => params[:cc], 
              :subject => params[:subject], 
              :message_text => message_text_utf8, 
              :message_html => message_html_utf8 
              ) 
.....

這是我要做的事：

路由實例：

post 'train_ability/:ability' => :train_ability, :as => 'train_ability' 

規格：

it "should increase the strength ability by one point and also update the strength_points by one if strength is the trained ability" do 
    @user.str = 10 
    @user.str_points = 0 
    @user.save! 
    post :train_ability, :ability => 'str' 
    @user.reload 
    flash[:error].should be_nil 
    @user.str_points.should == 1 
    @user.str.should == 11 
end
