Getting Guard tests to run AUTOMATICALLY

Rails
1

I’m going through Hartl’s Rails tutorial, which now uses Rails 4.2 and
Guard with minitest.

Having Guard up and running does not automatically run tests; I have to
press Enter to trigger the tests.

I can get the tests to run automatically upon starting Guard by changing
“guard :minitest, spring: true, all_on_start: false do” in the Guardfile
to
“guard :minitest, spring: true do”. (This change means that the
all_on_start parameter is set to true by default.)

How can I get the tests to run automatically when I modify files in the
app? While I don’t need this automatic testing to get through
railstutorial.org, I want to have this capability for working on more
serious apps. I’d like the tests to begin BEFORE I click on the
terminal
window that I have dedicated to Guard testing.

you need some watch directives in the Guardfile

you need some watch directives in the Guardfile, like so:

guard :rspec, cmd: ‘bundle exec rspec’ do

watch(%r{^spec/support/(.+).rb$}) { “spec” }

watch(‘spec/spec_helper.rb’) { “spec” }

watch(%r{^spec/.+_spec.rb$})

watch(%r{^app/(.+).rb$}) { |m| “spec/#{m[1]}_spec.rb” }

watch(%r{^app/controllers/(.+).rb$}) { |m|
“spec/integration/#{m[1]}_spec.rb” }

watch(%r{^app/models/(.+).rb$}) { |m| “spec/unit/#{m[1]}_spec.rb” }

end

I’ve tried out the complete sample app from
GitHub - mhartl/sample_app_3rd_edition: The sample app for the 3rd edition of the Ruby on Rails Tutorial to ensure that I didn’t
overlook something.

Now I realize that Guard does respond by automatically executing a test
when one of the files it watches changes. Unfortunately, it takes a few
MINUTES to respond and doesn’t even provide any visible indication
during
these minutes. I should note that my normal development environment is
in
Vagrant.

Why does Guard respond so slowly? Spring is supposed to speed up the
testing process, but I have a hard time believing that it’s
accomplishing
anything.

Have you installed the correct inotify bindings or is guard Running in
fallback Mode?
