#!/usr/bin/env bash
# Usage: . testlib.sh
# Simple shell command language test library.
#
# Tests must follow the basic form:
#
# begin_test "the thing"
# (
# set -e
# echo "hello"
# false
# )
# end_test
#
# When a test fails its stdout and stderr are shown.
#
# Note that tests must `set -e' within the subshell block or failed assertions
# will not cause the test to fail and the result may be misreported.
