使用嵌套资源测试控制器

ruby-on-rails-5.2 controller testing ruby ruby-on-rails

jperl · 技术社区 · 6 年前

我是鲁比的新手,我正在慢慢进步。我刚开始测试。

请注意,我还没有使用任何测试框架,仅仅是rails(5.2.3)提供的现成的框架。

我有很多书的作者 has_many :books belongs_to :author .

这些是我的装备:

图书.yml

tmaas:
  name: The Mysterious Affair at Styles
  published: 1920
  author_id: agatha_c

tgow:
  name: The Grapes of Wrath
  published: 1939
  author_id: john_s

作者.yml

agatha_c:
  name: Agatha Christie

john_s:
  name: John Steinbeck

我跑了

rails test test/controllers/books_controller_test.rb

但我发现这些测试有错误:

BooksControllerTest#test_should_update_book
BooksControllerTest#test_should_show_book
BooksControllerTest#test_should_get_edit
BooksControllerTest#test_should_destroy_book

Error:
BooksControllerTest#test_should_destroy_book:
ActiveRecord::RecordNotFound: Couldn't find Book with 'id'=445166326 [WHERE "books"."author_id" = ?]
    app/controllers/books_controller.rb:72:in `set_book'
    test/controllers/books_controller_test.rb:47:in `block (2 levels) in <class:BooksControllerTest>'
    test/controllers/books_controller_test.rb:46:in `block in <class:BooksControllerTest>'

问题来自于打电话:

author_book_url id: books(:tmaas).id, author_id: @author.id

edit_author_book_url id: books(:tmaas).id, author_id: @author.id

test "should destroy book" do
    assert_difference('Book.count', -1) do
      delete author_book_url id: books(:tmaas).id, author_id: @author.id
    end

    assert_redirected_to author_books_url(@author)
  end

@author 已设置为 setup

setup do
    @author = authors(:agatha_c)
  end

控制器中的set U book功能:

def set_book
      @book = @author.books.find(params[:id])
    end

我错过了什么?

这就是我通过测试的原因:

首先,你应该纠正 books.yml

tmaas:
  title: The Mysterious Affair at Styles
  published: 1920
  author: agatha_c

tgow:
  title: The Grapes of Wrath
  published: 1939
  author: john_s

这是我的测试 book_controller

创建操作的测试:

  test "should create book" do
    assert_difference('Book.count') do
      post author_books_url(@book.author), params: { book: { 
        author_id: @book.author_id, 
        title: @book.title,
        published: @book.published 
      }}
    end

    assert_redirected_to author_book_url(Book.last.author, Book.last)
  end

  test "should update book" do
    patch author_book_url(@book.author, @book), params: { book: { 
      author_id: @book.author_id, 
      title: @book.title,
      published: @book.published 
    } }
    assert_redirected_to author_book_url(@book.author, @book)
  end

销毁操作测试:

  test "should destroy book" do
    assert_difference('Book.count', -1) do
      delete author_book_url(@book.author, @book)
    end

    assert_redirected_to author_books_url(@book.author)
  end
