我想知道如何简单地允许所有异常在请求规范中间冒泡到 rspec。

我希望有一个例子可以说明这一点。假设我有以下请求规范和相应的应用程序代码：

# user_browses_posts_spec.rb
feature 'User views a post' do
  scenario 'this should fail with route missing' do
    FactoryGirl.create(:post)
    visit(root_path)
    click_on('View Post')
  end
end

# config/routes.rb
MyApp::Application.routes.draw do
  root to: 'posts#index'
  # notice I have not defined a :posts resource, so post_path should raise NoMethodError
end

# assume a totally standard app/controllers/posts_controller.rb

# app/views/posts/index.html.erb
<% @posts.each do |post| %>
  <%= link_to 'View Post', post_path(post) %>  # this line should fail
<% end %>

当我运行测试时，我看到的是：

Failure/Error: click_on('View Post')
Capybara::ElementNotFound:
  no …

我在〜/ Library/LaunchAgents中有以下plist文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>com.yogapo.test_launchd</string>

    <key>Program</key>
    <string>. /Users/luke/dev/data_yogapo/script/test_launchd.sh</string>

    <key>StartInterval</key>
    <integer>10</integer>

    <key>RunAtLoad</key>
    <true/>
  </dict>
</plist>

test_launchd.sh文件包含以下内容:

#! /bin/bash 

echo "hello world from test_launchd.sh" >> /Users/luke/dev/data_yogapo/log/development.log

当我手动运行test_launchd.sh时
. /Users/luke/dev/data_yogapo/script/test_launchd.sh ,结果与预期一致:该行出现在结尾处development.log

但是当我加载这个plist文件时,没有任何反应:

$ cd ~/Library/LaunchAgents
$ launchctl load com.yogapo.test_launchd.plist
$ launchctl list | grep yogapo
  -       1       com.yogapo.test_launchd

我已经尝试过使用和不使用RunAtLoad键.我在这里以及互联网上的其他地方看过其他答案.我已经按照教程,并没有发生任何事情.任何帮助非常感谢 - 谢谢!
