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：

不太确定这里发生了什么。期望值中的文本似乎被截断了？！？

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(如下(中，"编辑的位置"被截断。

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

然后是"JSON文本必须至少包含两个八位字节"的问题，这可能是相关的，也可能不是相关的，但在升级rspecrails&水豚.ds

想法？

Capybara 2.x和3.x之间的一个重大变化是，在Capybara 3.x中，文本的返回尽可能接近所显示的内容。这意味着当换行符显示给用户时，换行符现在会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"编辑标题\n编辑位置"，或者如果您不关心换行符，可以使用:normalize_ws选项=>expect(page).to have_text("Edited title Edited location", normalize_ws: true)
