11 clairehuang:mezzo$ guard 18:23:31 - info - guard using growlnotify send notifications. 18:23:31 - info - guard using terminaltitle send notifications. 18:23:31 - info - starting spork rspec using rspec, unknown loading spork.prefork block... spork ready , listening on 8989! 18:23:33 - info - spork server rspec started  18:23:33 - info - livereload waiting browser connect. 18:23:33 - info - guard::rspec running 18:23:33 - info - running specs /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/growl_notify-0.0.3/lib/growl_notify.rb:53: warning: instance variable @icon not initialized  18:23:34 - info - guard watching @ '/users/clairehuang/sites/mezzo' /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/celluloid-0.15.2/lib/celluloid/tasks.rb:76: warning: global variable `$celluloid_debug' not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/celluloid-0.15.2/lib/celluloid/tasks.rb:76: warning: global variable `$celluloid_debug' not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/celluloid-0.15.2/lib/celluloid/tasks.rb:76: warning: global variable `$celluloid_debug' not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/celluloid-0.15.2/lib/celluloid/tasks.rb:76: warning: global variable `$celluloid_debug' not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/celluloid-0.15.2/lib/celluloid/tasks.rb:76: warning: global variable `$celluloid_debug' not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/guard-2.6.1/lib/guard/interactor.rb:64: warning: instance variable @enabled not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/guard-2.6.1/lib/guard/interactor.rb:64: warning: instance variable @enabled not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/guard-2.6.1/lib/guard/interactor.rb:64: warning: instance variable @enabled not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/guard-2.6.1/lib/guard/interactor.rb:64: warning: instance variable @enabled not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/guard-2.6.1/lib/guard/interactor.rb:129: warning: instance variable @thread not initialized /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/pry-0.10.0/lib/pry/method.rb:383: warning: instance variable @method not initialized [1] guard(main)> 

if run rspec independently of guard, tests run okay , display output:

13 clairehuang:mezzo$ rspec /users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/spork-1.0.0rc4/lib/spork.rb:83: warning: assigned unused variable - method_name_with_spork run options: include {:focus=>true}  examples filtered out; ignoring {:focus=>true} f  failures:    1) donations /donations should display donations      failure/error: visit donations_path      nameerror:        undefined local variable or method `donations_path' #<rspec::examplegroups::donations::getdonations:0x007ffd038e5118>      # ./spec/requests/donations_spec.rb:6:in `block (3 levels) in <top (required)>'  deprecation warnings:  rspec::core::configuration#treat_symbols_as_metadata_keys_with_true_values= deprecated, set true default , setting false has no effect.   if need more of backtrace of these deprecations identify make necessary changes, can configure `config.raise_errors_for_deprecations!`, , turn deprecation warnings errors, giving full backtrace.  1 deprecation warning total  finished in 0.00081 seconds (files took 0.20421 seconds load) 1 example, 1 failure  failed examples:  rspec ./spec/requests/donations_spec.rb:5 # donations /donations should display donations 

how can tests run guard? thank in advance!

guardfile:
