如何使用RSpec测试我的销毁动作？

Question

In my Rails app, if a user wants to delete his own account he will first have to enter his password in my terminate view:

<%= form_for @user, :method => :delete do |f| %>

  <%= f.label :password %><br/>
  <%= f.password_field :password %>

  <%= f.submit %>

<% end %>

This is my UsersController :

def terminate
  @user = User.find(params[:id])
  @title = "Terminate your account"
end

def destroy
  if @user.authenticate(params[:user][:password])
    @user.destroy
    flash[:success] = "Your account was terminated."
    redirect_to root_path
  else
    flash.now[:alert] = "Wrong password."
    render :terminate
  end
end

The problem is that I can't seem to find a way to test this with RSpec.

What I have is this:

describe 'DELETE #destroy' do

  before :each do
    @user = FactoryGirl.create(:user)
  end

  context "success" do

    it "deletes the user" do
      expect{ 
        delete :destroy, :id => @user, :password => "password"
      }.to change(User, :count).by(-1)
    end

  end

end

However, this gives me an error:

ActionView::MissingTemplate:
Missing template users/destroy, application/destroy with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder]}. Searched in:
* "#<RSpec::Rails::ViewRendering::EmptyTemplatePathSetDecorator:0x007fa7f51310d8>"

Can anybody tell me what I'm missing here or suggest a better way to test this action?

Thanks for any help.

Answer 1

According to Rspec docs Views are stubbed by default . So, I think you should add controller.prepend_view_path 'users/destroy' in test method.

Answer 2

First wrong what I sow is:

In destroy action you have params[:user][:password] but in test you give only params[:id] and params[:password]

in controller you create @user in before_filter ?
