我想測試我的控制器。一切都很好,直到我試圖測試update
行動。如何在使用minitest的Rails中測試控制器的更新方法?
這是我的測試
require 'test_helper'
class BooksControllerTest < ActionController::TestCase
test "should not update a book without any parameter" do
assert_raises ActionController::ParameterMissing do
put :update, nil, session_dummy
end
end
end
這是我的控制器
class BooksController < ApplicationController
(...)
def update
params = book_params
@book = Book.find(params[:id])
if @book.update(params)
redirect_to @book
else
render 'edit'
end
end
(...)
def book_params
params.require(:book).permit(:url, :title, :price_initial, :price_current, :isbn, :bought, :read, :author, :user_id)
end
end
我的應用程序的書籍控制器路線如下:
books GET /books(.:format) books#index
POST /books(.:format) books#create
new_book GET /books/new(.:format) books#new
edit_book GET /books/:id/edit(.:format) books#edit
book GET /books/:id(.:format) books#show
PATCH /books/:id(.:format) books#update
PUT /books/:id(.:format) books#update
DELETE /books/:id(.:format) books#destroy
當我運行rake test
我得到:
1) Failure:
BooksControllerTest#test_should_not_update_a_book_without_any_parameter [/Users/acavalca/Sites/book-list/test/controllers/books_controller_test.rb:69]:
[ActionController::ParameterMissing] exception expected, not
Class: <ActionController::UrlGenerationError>
Message: <"No route matches {:action=>\"update\", :controller=>\"books\"}">
---Backtrace---

那麼,我在這裏錯過了什麼?我已經完成了搜索,但找不到任何東西。只有幾個RSpec的例子,看起來和我所做的很相似,但我還是沒有任何線索。
呃!它的工作,謝謝! :) –
