Ruby on rails 正在呈现的Rspec测试模板

我试图测试一个条件，成功注册后，成功模板由以下控制器代码呈现

def create
    @user = User.new(params[:user])
    if @user.save
      render :template => "success"
    else
      flash[:notice] = "Oops Somethings not quite right! :("
      render :action => "new"
    end
  end

我使用以下规范来测试这段代码

 before(:each) do
    @user = User.new
    @user.attributes = valid_attributes    
    @params = valid_attributes
    @user.stub!(:save).and_return(true)
  end


  def do_post
    post :create
  end


  it "should create new user " do
    count = User.count
    do_post
    user = User.new(@params)    
    user.save.should eql(true)
    User.count.should eql(count + 1)

  end

  it "should render the success page on successful signup" do
    do_post
    @user.save
    response.should render_template("success") if @user.save
  end

但是这个例子失败了，“它应该在成功注册时呈现成功页面”，并显示此错误消息

1)
'UsersController handling POST /users should render the success page on successful signup' FAILED
expected "success", got "users/new.html.erb"
./spec/controllers/users_controller_spec.rb:67:

成功视图是存储在视图/用户/中的模板，无需操作。我猜我犯了一个非常基本的错误，需要一些帮助。

您正在测试中存根

@user

变量，但是控制器将实例化一个新实例，因此存根将不在适当的位置

在这种情况下，仅为了模拟成功的保存调用而使用存根不是一个好主意。为什么不提供有效的数据，并确保操作成功

以下代码用于RSpec>2.1，它使用

expect

语法

before(:each) do
  @params = valid_attributes
end

it "should create new user" do
  @_before = User.count
  post :create, :user => @params

  expect(assigns(:user)).to_not be_new_record
  expect(User.count).to eq(@_before + 1)
end

it "should render the success page on successful signup" do
  post :create, :user => @params

  expect(response).to be_successful
  expect(response).to render_template("success")
end

最后，改变

render :template => "success"

到

对于以前的RSpec版本，或者如果必须使用

should

语法，请使用

before(:each) do
  @params = valid_attributes
end

it "should create new user" do
  @_before = User.count
  post :create, :user => @params

  assigns(:user).should_not be_new_record
  User.count.should == (@_before + 1)
end

it "should render the success page on successful signup" do
  post :create, :user => @params

  response.should be_successful
  response.should render_template("success")
end

就这样。我刚拿到。非常感谢。我仍在理解与Rspec合作的过程中。非常感谢。我会删除你上一次声明中的user.save条件。伙计，你的问题就是我的答案。

before(:each) do
  @params = valid_attributes
end

it "should create new user" do
  @_before = User.count
  post :create, :user => @params

  assigns(:user).should_not be_new_record
  User.count.should == (@_before + 1)
end

it "should render the success page on successful signup" do
  post :create, :user => @params

  response.should be_successful
  response.should render_template("success")
end
