Rails: Why isn't Guard waiting?

Question

I am trying to use Guard instead of Autotest for RSpec , but I'm somewhat confused by its behavior. When I run bundle exec guard it just launches a pry window. I thought it is supposed to behave like Autotest where it just continues to run tests in the background every time there is a change. What am I missing here?

When I launch bundle exec guard , this is what I get:

18:52:44 - INFO - Guard is using TerminalTitle to send notifications.
18:52:44 - INFO - Guard::RSpec is running
18:52:44 - INFO - Guard is now watching at '/path/to/my/application'
[1] guard(main)> 

I'm not really sure what to make of this.

Have you generated your Guardfile? (./Guardfile in your app directory). Mine looks like this:

# A sample Guardfile
# More info at https://github.com/guard/guard#readme

guard :rspec do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$})          { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Capybara features specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml|slim)$})     { |m| "spec/features/#{m[1]}_spec.rb" }

  # Turnip features and steps
  watch(%r{^spec/acceptance/(.+)\.feature$})
  watch(%r{^spec/acceptance/steps/(.+)_steps\.rb$})   { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'spec/acceptance' }
end

Your output listed above looks correct, Guard gives you an interactive shell as well as triggering things when files change.

使用-i选项运行它应该会有所帮助

bundle exec guard -i

Guard is running Pry for user interactions with it. Probably you haven't set to run RSpec guard at startup. To run it manually type rspec and hit return. It will run your Guard. To run all guards (if you have more than this one) just type all and hit return.

PS Guard is still watching and will run your guard on file change, but it is showing Pry prompt to allow user interactions (described above).
