+# 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.
+#
+# 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
