我跟随this教程，直到现在我还没有遇到任何重大问题，但是当我突然尝试运行测试（或Guard）时，它突然开始失败。由于Bootstrap导轨测试失败 - 导轨4
对于每一次失败，它提醒我
ERROR["test_should_get_home", StaticPagesControllerTest, 1.3221390806138515]

，我可以破译 - 它试图利用引导和不能。
也许我对TDD不够熟悉，但为什么它试图让bootstrap渲染标题？这是由于部分？
我发现了很多其他帖子，但是大多数人都死了，或者来自Rails 3，只是重新启动服务器解决了它。
我能解决它，但修改我的Gemfile。我从顶部移动了gem 'bootstrap-sass', '3.3.6'，变成了
group :assets, :test, :development do
gem 'bootstrap-sass', '3.3.6'
end
块。我认为块外的任何宝石都是永久加载的，但事实并非如此？我是否应该在未来坚持这种风格？
（配售为符号起见整个的Gemfile）
source 'https://rubygems.org'
gem 'rails', '5.0.0.1'
gem 'puma', '3.4.0'

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

编辑：添加在两个测试中的要求。
应用测试
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require "minitest/reporters"
Minitest::Reporters.use!
class ActiveSupport::TestCase
# Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
fixtures :all
include ApplicationHelper
# Add more helper methods to be used by all tests here...
end
具体测试
需要 'test_helper'
class SiteLayoutTest < ActionDispatch::IntegrationTest
test "layout links" do
get root_path
assert_template 'static_pages/home'
assert_select "a[href=?]", root_path, count: 2
assert_select "a[href=?]", help_path
assert_select "a[href=?]", about_path
assert_select "a[href=?]", contact_path
get contact_path
assert_select "title", full_title("Contact")
get signup_path
assert_select "title", full_title("Sign-Up")
end
end
找你问题停止从'app/assets/stylesheets/custom.scss：1'开始是否有导入指令？你的失败测试是怎样的？ – slowjack2k
@ slowjack2k本身添加了精确的测试。 – DNorthrup
