Capybara не находит метатеги

Ответ 1

Решение заключалось в использовании :visible => false либо в find, либо в have_selector:

page.should have_css 'meta[name="description"]', :visible => false

или

page.find 'meta[name="description"]', :visible => false

Если вы хотите проверить более конкретную мета, включая текст описания и т.д.:

https://gist.github.com/Lordnibbler/6247531

RSpec::Matchers.define :have_meta do |name, expected|
  match do |actual|
    has_css?("meta[name='#{name}'][content='#{expected}']")
  end

  failure_message_for_should do |actual|
    actual = first("meta[name='#{name}']")
    if actual
      "expected that meta #{name} would have content='#{expected}' but was '#{actual[:content]}'"
    else
      "expected that meta #{name} would exist with content='#{expected}'"
    end
  end
end

RSpec::Matchers.define :have_title do |expected|
  match do |actual|
    has_css?("title", :text => expected)
  end

  failure_message_for_should do |actual|
    actual = first("title")
    if actual
      "expected that title would have been '#{expected}' but was '#{actual.text}'"
    else
      "expected that title would exist with '#{expected}'"
    end
  end
end

Затем найдите мета так:

page.should have_meta(:description, 'Brand new Ruby on Rails TShirts')
