RSpec 不会自动确定视图规范类型

Question

我有一个位于app/views/shared/_card_instance.html.haml 的视图。以下规范通过：

spec/views/_card_instance.html.haml_spec.rb

require 'spec_helper'

describe 'card_instance partial', type: :view do
  it 'should just display the missing slot if present' do
    card = double(:card, missing_slot: 'Rare')
    render 'shared/card_instance', card: card

    expect(rendered).to have_css('.card', text: 'Rare')
  end
end

但是，如果我删除 type: :view，它会失败：

Failures:

  1) card_instance partial should just display the missing slot if present
     Failure/Error: render 'shared/card_instance', card: card
     NoMethodError:
       undefined method `render' for #<RSpec::ExampleGroups::CardInstancePartial:0x5d02b50>
     # ./spec/views/_card_instance.html.haml_spec.rb:6:in `block (2 levels) in <top (required)>'

为什么？ RSpec 不应该根据路径将规范标识为视图规范吗？

我相信这种行为已经改变：
