标签: serverspec

Serverspec站点的"高级提示"部分显示了使用相同测试集测试多个主机的示例.我已经建立了一个我自己的例子(https://gist.github.com/neilhwatson/81249ad393800a76a8ad),但是有问题.

第一个问题是测试在第一次失败时停止,而不是继续通过该批次并保持计数.第二个是故障输出并不表示故障发生在哪个主机上.我该怎么做才能解决这些问题并为所有主机生成最终报告？

问题:

如果我使用以下命令之一运行ServerSpec(基于RSpec)Rake:

• rake
• rake spec
• rake spec:all
• rake spec:<host>
• bundle exec rake
• ...

Rake stdout在serverspec输出之前打印它执行的命令:

/usr/bin/ruby1.9.1 
-I/var/lib/gems/1.9.1/gems/rspec-core-3.1.6/lib:/var/lib/gems/1.9.1/gems/rspec-support-3.1.2/lib 
/var/lib/gems/1.9.1/gems/rspec-core-3.1.6/exe/rspec 
--pattern spec/<host>/\*_spec.rb

如果我手动传递目标主机来rspec这样...

TARGET_HOST=<host> rspec

......行不会不露面.

题:

如何防止Rake输出此行/命令？

我正在使用由...生成的默认Rakefile serverspec-init.

require 'rake'
require 'rspec/core/rake_task'

task :spec    => 'spec:all'
task :default => :spec

namespace :spec do
  targets = []
  Dir.glob('./spec/*').each do |dir|
    next unless File.directory?(dir)
    targets << File.basename(dir)
  end

  task :all     => targets
  task :default => :all

  targets.each do …

我已经构建了一些serverspec代码来在多个主机上运行一组测试.问题是当任何测试失败时,测试在当前主机上停止.即使测试失败,我希望它继续所有主机.

Rakefile:

namespace :spec do
  task :all => hosts.map {|h| 'spec:' + h.split('.')[0] }
  hosts.each do |host|
    begin
      desc "Run serverspec to #{host}"
      RSpec::Core::RakeTask.new(host) do |t|
        ENV['TARGET_HOST'] = host
        t.pattern = "spec/cfengine3/*_spec.rb"
      end
    rescue
    end
  end
end

完整代码:https: //gist.github.com/neilhwatson/1d41c696102c01bbb87a

我从下面的代码部分得到了上述错误.原因是什么？

 1  require 'spec_helper'
 2
 3  before(:all) do
 4    puts "ServerSpec tests on #{ENV['TARGET_HOST']}"
 5  end

我想检查一下现有目录是否为空（不包含任何文件或子目录）。

我尝试了以下方法：

describe file('/path/to/file') do
    it { should be_empty }
end

但这是行不通的。（当然，因为在文档中没有提到。）

重要提示：我不想测试目录是否存在-它确实存在并且无法更改。

现在，我的解决方案如下所示：

describe command('ls /data/nginx/cache/services | grep -q .') do
    its(:exit_status) { should eq 1 }
end

但这不使用Serverspec资源类型“文件”。有没有更好的方法来测试文件夹为空？
