我有一个名为get_books_from_amazon的辅助方法,它执行API调用并返回一系列书籍。我无法弄清楚如何在我的请求规范中将其存根。
module BooksHelper
def get_books_from_amazon(search_term)
...
end
end
class StaticController < ApplicationController
include BooksHelper
def resources
@books = get_books_from_amazon(search_term)
end
end
我在我的规范中尝试了以下内容,但都无济于事:
# spec/requests/resource_pages_spec.rb
...
describe "Navigation" do
it "should do such and such" do
BooksHelper.stub!(:get_books_from_amazon).and_return(book_array)
StaticHelper.stub!(:get_books_from_amazon).and_return(book_array)
ApplicationHelper.stub!(:get_books_from_amazon).and_return(book_array)
StaticController.stub!(:get_books_from_amazon).and_return(book_array[0..4])
ApplicationController.stub!(:get_books_from_amazon).and_return(book_array[0..4])
request.stub!(:get_books_from_amazon).and_return(book_array)
helper.stub!(:get_books_from_amazon).and_return(book_array)
controller.stub!(:get_books_from_amazon).and_return(book_array)
self.stub!(:get_books_from_amazon).and_return(book_array)
stub!(:get_books_from_amazon).and_return(book_array)
visit resources_path
save_and_open_page
end

在这种情况下,肯迪克的回应是很好的建议。
我已添加此内容,以防有人真正寻找原始问题的答案:
ActionView::Base.any_instance.stub(:helper_method) { "substitute return value" }

助手通常用于清理演示文稿“逻辑”,因此我不会在辅助方法中调用类似于亚马逊API的内容。
相反,将该方法移动到可以从控制器调用的普通Ruby类。 一个例子可能是:
class AmazonBookRetriever
def get_books_from_amazon
#code here
end
end
然后您的控制器可以调用它:
def resources
@books = AmazonBookRetriever.new.get_books_from_amazon(params[:search_term])
end
这应该使嘲弄变得更容易。您可以在#new
上存根AmazonBookRetriever
以返回模拟,并验证它是否收到get_books_from_amazon
消息。
