Question

根据capybara docs，expect(page).to have_content语法是合法的，但它似乎不起作用

我已添加spec文件和

下面的错误

require 'spec_helper.rb'

feature "Looking up recipes", js: true do
  before do
    Recipe.create!(name: 'Baked Potato w/ Cheese')
    Recipe.create!(name: 'Garlic Mashed Potatoes')
    Recipe.create!(name: 'Potatoes Au Gratin')
    Recipe.create!(name: 'Baked Brussel Sprouts')
  end

  scenario "finding recipes" do
    visit '/'
    fill_in "keywords", with: "baked"
    click_on "Search"

    expect(page).to have_content("Baked Potato")
    expect(page).to have_content("Baked Brussel Sprouts")
  end
end

运行spec时出错：

sai@saip:~/rails_apps/receta$ rspec spec/features/search_spec.rb

Answer 1

您为该语法使用了错误的RSpec版本。使用expect(...).to ...是在RSpec 3+中编写测试的可接受方式。您正在使用2.99。

您的语法是

page.should have_content("Baked Potato")

你应该真的升级RSpec。

期待（页面）.to_content不工作
