如何使用 RSpec 测试这种销毁操作? [英] How can this destroy action be tested with RSpec?

问题描述

在我的 Rails 应用中，如果 user 想要删除他自己的帐户，他首先必须在我的 terminate 视图中输入他的密码:

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 %>

这是我的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

问题是我似乎无法找到使用 RSpec 进行测试的方法.

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

我拥有的是这个:

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

但是，这给了我一个错误:

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>"

谁能告诉我我在这里遗漏了什么或建议一个更好的方法来测试这个动作?

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

感谢您的帮助.

推荐答案

好的，这是我的解决方案:

OK, this is my solution:

describe 'DELETE #destroy' do

  context "success" do

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

  end

end

我之前的 before :each 调用没有用(毕竟这不是集成测试).密码必须像这样传入::user =>{:密码=>@user.password} 直到阅读这个线程.

The before :each call I had before was useless (this is not an integration test after all). The password has to be passed in like this: :user => {:password => @user.password} which I didn't know until reading this thread.
