Question

升级rspec-rails (2.5.2 -> 3.8.1)和capybara (2.18.0 -> 3.10.1)后，两个失败的规范：

不太确定这里发生了什么。看起来期望中的文本被截断了吗？！？

  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（如下）中，“编辑的位置”被截断了。

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

然后存在一个“ JSON文本必须至少包含两个八位字节”的问题，该问题可能相关也可能不相关，但是在升级rspec-rails和capybara.ds之前通常会通过

有想法吗？

Answer 1

在Capybara 2.x和3.x之间的一大变化是在Capybara 3.x中，文本的返回尽可能接近所显示的内容。这意味着在向用户显示https://github.com/teamcapybara/capybara/blob/master/UPGRADING.md时，换行符现在已包含在返回的文本中。您需要在spec / features / stories / editing_spec.rb：115上将期望的文本更改为“已编辑标题\ n已编辑位置”，或者，如果您不关心换行符，则可以使用:normalize_ws选项=> expect(page).to have_text("Edited title Edited location", normalize_ws: true)

RSpec-JSON文本必须至少包含两个八位字节
