guard_test_runner.rb:1:in `require': cannot load such file

Question

I am attempting to have a .Guardfile that all of my Rails projects can run off in my user directory.

The .Guardfile contents is outlined below:

# Defines the matching rules for Guard.
guard :test, all_on_start: false do
  watch(%r{^test/(.*)/?(.*)_test\.rb$})
  watch('test/test_helper.rb') { 'test' }
  watch('config/routes.rb')    { 'test' }
  watch(%r{^app/models/(.*?)\.rb$}) do |matches|
    "test/models/#{matches[1]}_test.rb"
  end
  watch(%r{^app/controllers/(.*?)_controller\.rb$}) do |matches|
    resource_tests(matches[1])
  end
  watch(%r{^app/views/([^/]*?)/.*\.html\.erb$}) do |matches|
    ["test/controllers/#{matches[1]}_controller_test.rb"] +
    integration_tests(matches[1])
  end
  watch(%r{^app/helpers/(.*?)_helper\.rb$}) do |matches|
    integration_tests(matches[1])
  end
  watch('app/views/layouts/application.html.erb') do
    'test/integration/site_layout_test.rb'
  end
  watch('app/helpers/sessions_helper.rb') do
    integration_tests << 'test/helpers/sessions_helper_test.rb'
  end
  watch('app/controllers/sessions_controller.rb') do
    ['test/controllers/sessions_controller_test.rb',
     'test/integration/users_login_test.rb']
  end
  watch('app/controllers/account_activations_controller.rb') do
    'test/integration/users_signup_test.rb'
  end
end

# Returns the integration tests corresponding to the given resource.
def integration_tests(resource = :all)
  if resource == :all
    Dir["test/integration/*"]
  else
    Dir["test/integration/#{resource}_*.rb"]
  end
end

# Returns the controller tests corresponding to the given resource.
def controller_test(resource)
  "test/controllers/#{resource}_controller_test.rb"
end

# Returns all tests for the given resource.
def resource_tests(resource)
  integration_tests(resource) << controller_test(resource)
end

However when I run guard in the root of my rails directory I get the following issue..

11:53:04 - INFO - Guard::Test 2.0.6 is running, with Test::Unit 3.1.3!
11:53:04 - INFO - Guard is now watching at       '/../../Documents/Projects/..'

Has anybody got any ideas?

Answer 1

I ran into the same issue using minitest with Rails 4. I added:

gem guard
gem guard-minitest

To my Gemfile and then generated the guard file with guard init minitest and everything started working correctly.

Answer 2

I had a similar experience as well. The issue began after I initialized the Guard gem in my project by running the code below in my terminal

bundle exec guard init

I tried a lot of solutions to fix the issue. Such as

1. Uninstalling the Guard gem
2. Uninstalling the Guard-minitest gem
3. Deleting Guardfile in the root directory of my project

But none seemed to work, as I was still facing the same issue. All I had to do was to recreate the project, and skipped the installation and initialization of the Guard gem and the Guard-minitest gem.

I guess there was an incompatibility issue with the gem.

That's all.

I hope this helps
