使用 Guard-Spork 时 Guard 会导致 Spork 崩溃

Question

我已经关注了 RailsCasts 上的“我如何测试”截屏视频，但是我遇到了spork 的问题

$ 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.

当我尝试在单独的终端窗口中运行 spork 时，它没有帮助，因为一旦我运行 guard 它就会立即被杀死

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

如果我就跑spork 然后尝试 rspec 。 --drb，它工作得很好。 这是要点链接以及我的 Gemfile、Guardfile 和 spec_helper.rb

Answer 1

您应该将：更改

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

为：

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

Answer 2

这个问题实际上是由 guard 在加载之前杀死 spork 造成的，这是我的较慢 MacBook pro 上的问题。

解决方案是通过 :wait => 增加等待时间Guardfile 中的 120，例如

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