Usage

Please read Guard usage doc.

Guardfile

Guard::RSpec can be adapted to all kinds of projects, some examples:

Standard RubyGem project

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" }
end

Typical Rails app

guard :rspec do
  watch('spec/spec_helper.rb')                        { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$})          { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^lib/(.+)\.rb$})                           { |m| "spec/lib/#{m[1]}_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"] }
end

Please read Guard doc for more information about the Guardfile DSL.

Options

Guard::RSpec 4.0 use now a more simple approach with the new cmd option that let you precisely define which rspec command will be launched on each run. As example if you want to support Spring with a custom formatter (progress by default) use:

guard :rspec, cmd: 'spring rspec -f doc' do
  # ...
end

Running with bundler

Running bundle exec guard will not run the specs with bundler. You need to change the cmd option to bundle exec rspec:

guard :rspec, cmd: 'bundle exec rspec' do
  # ...
end

List of available options:

cmd: 'zeus rspec'      # Specify a custom rspec command to run, default: 'rspec'
spec_paths: ['spec']   # Specify a custom array of paths that contain spec files
failed_mode: :focus    # What to do with failed specs
                       # Available values:
                       #  :focus (default) - focus on the first 10 failed specs, rerun till they pass
                       #  :keep - keep failed specs until they pass (add them to new ones)
                       #  :none - just report
all_after_pass: true   # Run all specs after changed specs pass, default: false
all_on_start: true     # Run all the specs at startup, default: false
launchy: nil           # Pass a path to an rspec results file, e.g. ./tmp/spec_results.html
notification: false    # Display notification after the specs are done running, default: true
run_all: { cmd: 'custom rspec command', message: 'custom message' } # Custom options to use when running all specs

Using Launchy to view rspec results

guard-rspec can be configured to launch a results file in lieu of outputing rspec results to the terminal. Configure your Guardfile with the launchy option:

guard :rspec, cmd: 'rspec -f html -o ./tmp/spec_results.html', launchy: './tmp/spec_results.html' do
  # ...
end
