Question

我收到此错误：

comments_controller_spec.rb:12: syntax error, unexpected tLABEL, expecting '='
...ate, post_id: post.id, comment: attributes_for(:comment)}.to...
                           ^

运行我的spec文件comments_controller_spec.rb：

require 'rails_helper'
describe CommentsController do 

  describe "POST #create" do 
    comment = create(:comment)
    post = comment.post

    it "properly creates a comment" do 
      expect{post :create, post_id: post.id, comment: attributes_for(:comment)}.to change(Comment, :count).by(1)
    end

  end
end

从我从阅读其他帖子中收集到的内容是我没有正确关闭块或哈希。我一直在看这个，我找不到任何未正确关闭的东西。它似乎指向我的post方法作为问题的根源，但我相信我已经正确地传递了它的所有参数。所以我不确定还有什么可能是错的。谁能告诉我们这里发生了什么？谢谢你的帮助。

更新：

我把测试改为：

it "properly creates a comment" do 

      expect {post(:create, post_id: post.id, comment: attributes_for(:comment))}.to change(Comment, :count).by(1)
end

现在错误信息是：

CommentsController POST #create properly creates a comment
     Failure/Error: expect {post(:create, post_id: post.id, comment: attributes_for(:comment))}.to change(Comment, :count).by(1)

     ArgumentError:
       wrong number of arguments (given 2, expected 0)
     # ./spec/controllers/comments_controller_spec.rb:13:in `block (4 levels) in <top (required)>'
     # ./spec/controllers/comments_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

这是我的post_factory.rb：

FactoryGirl.define do 

  factory :post do 
    content "this is post content!"
    user
  end
end

Answer 1

我相信change匹配器需要一个块：

expect{post :create, post_id: post.id, comment: attributes_for(:comment)}.to change{ Comment.count }.by(1)

如果不是这样，我会尝试在post的参数周围添加括号，以为解析器可能存在问题：

expect{ post(:create, post_id: post.id, comment: attributes_for(:comment)) }.to change{ Comment.count }.by(1)

作为最后的手段，我会这样做：

expect do
  post(:create, post_id: post.id, comment: attributes_for(:comment)) 
end.to change{ Comment.count }.by(1)

Answer 2

尝试以下方法：

var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = SecurityMode.TransportCredentialOnly;

无法弄清楚这个错误有什么问题：语法错误，意外的tLABEL，期待'='，在我的Rspec测试中？
