#!/usr/bin/env bash
# Usage: script/test [file] [adapter]... -- [test/unit options]
# Runs the test suite against a local server spawned automatically in a
# thread. After tests are done, the server is shut down.
#
# If filename arguments are given, only those files are run. If arguments given
# are not filenames, they are taken as words that filter the list of files to run.
#
# Examples:
#
#   $ script/test
#   $ script/test test/env_test.rb
#   $ script/test excon typhoeus
#
#   # Run only tests matching /ssl/ for the net_http adapter, with SSL enabled.
#   $ SSL=yes script/test net_http -- -n /ssl/
#
#   # Run against multiple rbenv versions
#   $ RBENV_VERSIONS="1.9.3-p194 ree-1.8.7-2012.02" script/test
