Question

我正在为控制器编写规范：

it 'should call the method that performs the movies search' do
  movie = Movie.new
  movie.should_receive(:search_similar)
  get :find_similar, {:id => '1'}
end

我的控制器看起来像：

def find_similar
 @movies = Movie.find(params[:id]).search_similar
end

运行rspec后，我得到以下内容：

Failures:
1) MoviesController searching by director name should call the method that performs the movies search
 Failure/Error: movie.should_receive(:search_similar)
   (#<Movie:0xaa2a454>).search_similar(any args)
       expected: 1 time
       received: 0 times
 # ./spec/controllers/movies_controller_spec.rb:33:in `block (3 levels) in <top (required)>'

我似乎理解并接受，因为在我的控制器代码中我调用了Class（Movie）方法，我没有看到任何方法将“find_similar”与在规范中创建的对象连接。

所以问题是 - ＆gt;什么是检查方法是否在对象上调用的方法，在spec？

中创建

Answer 1

it 'should call the method that performs the movies search' do
  movie = Movie.new
  movie.should_receive(:search_similar)
  Movie.should_receive(:find).and_return(movie)
  get :find_similar, {:id => '1'}
end

<子> 值得一提的是，我完全反对这些存根测试，他们只是让代码更改变得更难，实际上只测试代码结构。

Answer 2

首先，您的电影尚未保留。

第二个，而不是事实，它将具有身份1

所以试试这个

it 'should call the method that performs the movies search' do
  movie = Movie.create
  movie.should_receive(:search_similar)
  get :find_similar, {:id => movie.id}
end

RSpec的。如何检查对象方法是否被调用？
