当使用防护叉时防护Spork崩溃

Question

我跟着RailsCasts的"我如何测试"截屏视频,然而我遇到了spork问题

$ guard
Guard is now watching at '/Users/darth/projects/auth-before'
Starting Spork for Test::Unit & RSpec 
Couldn't find a supported test framework that begins with 'testunit'

Supported test frameworks:
( ) Cucumber
(*) RSpec

Legend: ( ) - not detected in project   (*) - detected
Using RSpec
Preloading Rails environment
Loading Spork.prefork block...
Spork is ready and listening on 8989!
ERROR: Could not start Spork server for Test::Unit & RSpec. Make sure you can use it manually first.

# here I get growl notification "Test::Unit & RSpec NOT started

Guard::RSpec is running, with RSpec 2!
Running all specs
Running tests with args ["--color", "--format", "progress", "--format", "Guard::RSpec::Formatter::NotificationRSpec", "--out", "/dev/null", "--require", "/Users/darth/.rvm/gems/ruby-1.9.2-p290/gems/guard-rspec-0.5.0/lib/guard/rspec/formatters/notification_rspec.rb", "spec"]...
.

Finished in 14.47 seconds

Done.

当我尝试spork在一个单独的终端窗口中运行时,它没有帮助,因为它在我运行后立即被杀死guard

$ spork
Using RSpec
Preloading Rails environment
Loading Spork.prefork block...
Spork is ready and listening on 8989!
Killed: 9

如果我只是跑spork,然后尝试rspec . --drb,它的工作正常.这里是我的Gemfile,Guardfile和spec_helper.rb的gist链接

Answer 1

你应该改变:

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, 
               :rspec_env => { 'RAILS_ENV' => 'test' }, 
               :wait => 120

至:

guard 'spork', :rspec_env => { 'RAILS_ENV' => 'test' }, 
                cucumber: false, 
                test_unit: false 

Answer 2

这个问题实际上是由它甚至可以加载之前的guard杀戮引起的spork,这对我速度较慢的 MacBook pro来说是一个问题.

解决的办法是增加等待时间:wait => 120中Guardfile,例如,

guard 'spork', :cucumber_env => { 'RAILS_ENV' => 'test' }, 
               :rspec_env => { 'RAILS_ENV' => 'test' }, :wait => 120
    ....
