RSpec + Factory_Girl 查看测试

Question

再次，似乎被困在一个简单的视图测试上。代码如下：

require 'spec_helper'

describe "posts/show.html.erb" do
  setup do
    @post = Factory(:post)
  end

  it "should not render a canonical link rel" do
    get :show, :id => @post.id
    response.should_not have_tag("link[rel=?]", "canonical")
  end
end

当我从控制台执行 Factory(:post) 时，没有问题，可以完美地创建它。但是当我在命令行上运行它时，我得到以下信息：

rspec spec/views/posts/show.html.erb_spec.rb 
F

Failures:

  1) posts/show.html.erb should not render a canonical link rel
     Failure/Error: get :show, :id => @post.id
     RuntimeError:
       Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
     # ./spec/views/posts/show.html.erb_spec.rb:11

Finished in 0.06532 seconds
1 example, 1 failure

任何想法我错过了什么？

Answer 1

你想使用before each:

before(:each) do
    @post = Factory(:post)
end

或

before do
  @post = Factory(:post)
end

简写。

而不是设置块。
