RSpec - JSON 文本必须至少包含两个八位字节

Question

升级rspec-rails (2.5.2 -> 3.8.1) 和capybara (2.18.0 -> 3.10.1) 后的两个失败规范：

不太清楚这里发生了什么。看起来期望中的文本被截断了？！？

  let(:story_attributes) do
    {
      title:       'Edited title',
      description: 'Edited location',
      start_year:  '2001',
      start_month: 'December',
      start_day:   '5',
      end_year:    '2001',
      end_month:   'October',
      end_day:     '10',
      is_range:    true,
      cover_image: {
        url: 'http://placehold.it/edited.png'
      }
    }
  end

  ... 

  within 'section.story-cover' do
    expect(page).to have_text 'Edited title'
    expect(page).to have_text 'Edited location'
    expect(page).to have_text 'December 5th - October 10th, 2001'
  end

在第一个失败的示例（下）中，“已编辑位置”被截断。

在第二个示例 expect(page).to have_text 'Edited title Edited location' 中，仅找到“已编辑的标题\n已编辑的位置”。

然后是这个“JSON 文本必须至少包含两个八位字节”的问题，它可能相关也可能不相关，但这在升级 rspec-rails 和 capybara.ds 之前曾经通过

想法？

Answer 1

Capybara 2.x 和 3.x 之间的一个重大变化是，在 Capybara 3.x 中，返回的文本尽可能接近显示的内容。这意味着当它们显示给用户时，换行符现在包含在返回的文本中 - https://github.com/teamcapybara/capybara/blob/master/UPGRADING.md。您需要在 spec/features/stories/editing_spec.rb:115 将预期文本更改为“已编辑标题\n已编辑位置”，或者如果您不关心换行符，您可以使用 :normalize_ws 选项 => @987654324 @
