Question

我正在尝试运行这种最简单的功能测试。使用RSpec 3语法，ruby-2.5.1、2019年使用的rails 5：

RSpec.feature "Roots", type: :feature do
  fixtures :page_model
  fixtures :event
  fixtures :level
  fixtures :phase

  it "loads the homepage" do
    visit root_path
    expect(page).to have_content 'Team'
  end

  it "loads a page" do
    p = page(:page2)
    puts p.name
    visit page_path(p)
    expect(page).to have_content p.body
  end
end

但是我总是会出错

 NoMethodError:
   undefined method `visit' for []:Array
 # /Users/someuser/.rvm/gems/ruby-2.5.1@rails5/gems/capybara-3.16.1/lib/capybara/dsl.rb:51:in `block (2 levels) in <module:DSL>'
 # ./spec/features/root_spec.rb:10:in `block (2 levels) in <top (required)>'

请注意，错误发生在行

visit root_path

与页面完全无关。

我将其范围缩小到第一个Fixture文件：如果我将其注释掉

RSpec.feature "Roots", type: :feature do
  # fixtures :page
  fixtures :event
  fixtures :level
  fixtures :phase

  it "loads the homepage" do
    visit root_path
    expect(page).to have_content 'Team'
  end
end

然后测试运行没有错误并且成功。但我找不到问题与夹具文件：

page1:
  id: 1
  cached_slug: info
  name: "Information"
  body: "this and that"
  created_at: "2011-03-01 10:09:53"
  updated_at: "2016-07-21 12:15:46"
  visibility: visibility_public

page2:
  id: 2
  cached_slug: impressum
  name: "Impressum + Kontakt"
  body: "dies ist ein Projekt"
  created_at: "2011-03-01 10:09:53"
  updated_at: "2016-12-05 10:42:30"
  visibility: visibility_public

Answer 1

灯具不能称为page.yml，因为这会创建一种从夹具加载的方法page()。这会覆盖page 由visit隐式设置：代表页面的对象刚刚加载。

我必须将Fixture文件的文件名更改为page_model.yml，然后加载它：

RSpec.feature "Roots", type: :feature do
  fixtures :page_model
  fixtures :event
  fixtures :level
  fixtures :phase

  it "loads the homepage" do
    visit root_path
    expect(page).to have_content 'Team'
  end

  it "loads a page" do
    p = page_model(:page1)
    puts p.name
    visit page_path(p)
    expect(page).to have_content p.body
  end
end

请注意，现在我可以使用page_model(:page1)来加载灯具了。

在Set model name in fixtures as metadata中，我了解到您可以在夹具文件中指定模型的类别：

_fixture:
  model_class: Page

page1:
  id: 1
  cached_slug: info
  name: "Information"
  body: "this and that"
  created_at: "2011-03-01 10:09:53"
  updated_at: "2016-07-21 12:15:46"
  visibility: visibility_public

page2:
  id: 2
  cached_slug: impressum
  name: "Impressum + Kontakt"
  body: "dies ist ein Projekt"
  created_at: "2011-03-01 10:09:53"
  updated_at: "2016-12-05 10:42:30"
  visibility: visibility_public

在2019年RSpec 3功能测试中对[]：Array的未定义方法`visit'
