NAME

       cli.rb:123:in - sass-spec testsuite for Sass implementions

SYNOPSIS

       sass-spec.rb [options] [spec_directory...]

EXAMPLES

              Run   `sassc  --style  compressed  input.scss`:  ./sass-spec.rb  -c  'sass  --style
              compressed'

              Run tests only in the spec/basic folder: ./sass-spec.rb spec/basic

       This script will search for all files under the spec (or  specified)  directory  that  are
       named  input.scss.  It  will then run a specified binary and check that the output matches
       the expected output. If you want set up your own test suite, follow a similar hierarchy as
       described in the initial comment of this script for your test hierarchy.

       This  command  can also be used to annotate tests to control which tests are ran and when.
       For details: ./sass-spec.rb annotate -h
