Guardfile
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
## Uncomment and set this to only include directories you want to watch
# directories %w(app lib config test spec features) \
# .select{|d| Dir.exist?(d) ? d : UI.warning("Directory #{d} does not exist")}
## Note: if you are using the `directories` clause above and you are not
## watching the project directory ('.'), then you will want to move
## the Guardfile to a watched dir and symlink it back, e.g.
#
# $ mkdir config
# $ mv Guardfile config/
# $ ln -s config/Guardfile .
#
# and, you'll have to watch "config/Guardfile" instead of "Guardfile"
guard :minitest, all_on_start: false do
# with Minitest::Unit
watch(%r{^test/(.*)_test\.rb$})
watch(%r{^lib/(.+)\.rb$}) { |m| "test/#{m[1]}_test.rb" }
watch(%r{^test/test_helper\.rb$}) { "test" }
end
