# Simple test harness infrastructure
#
# Copyright 2005 by Rob Landley
# This file defines two main functions, "testcmd" and "optional". The
# first performs a test, the second enables/disables tests based on
# configuration options.
# The following environment variables enable optional behavior in "testing":
# DEBUG - Show every command run by test script.
# VERBOSE - Print the diff -u of each failed test case.
# If equal to "fail", stop after first failed test.
# "nopass" to not show successful tests
#
# The "testcmd" function takes five arguments:
# $1) Description to display when running command
# $2) Command line arguments to command
# $3) Expected result (on stdout)
# $4) Data written to file "input"
# $5) Data written to stdin
#
# The "testing" function is like testcmd but takes a complete command line
# (I.E. you have to include the command name.) The variable $C is an absolute
# path to the command being tested, which can bypass shell builtins.
#
# The exit value of testcmd is the exit value of the command it ran.
#
# The environment variable "FAILCOUNT" contains a cumulative total of the
# number of failed tests.
#
# The "optional" function is used to skip certain tests (by setting the
# environment variable SKIP), ala:
# optional CFG_THINGY
#
# The "optional" function checks the environment variable "OPTIONFLAGS",
# which is either empty (in which case it always clears SKIP) or
# else contains a colon-separated list of features (in which case the function
# clears SKIP if the flag was found, or sets it to 1 if the flag was not found).
export FAILCOUNT=0
export SKIP=
# Helper functions
# Check config to see if option is enabled, set SKIP if not.
