# Using this file in a test
# =========================
#
# The typical skeleton of a test looks like this:
#
# #!/bin/sh
# . "${srcdir=.}/init.sh"; path_prepend_ .
# Execute some commands.
# Note that these commands are executed in a subdirectory, therefore you
# need to prepend "../" to relative filenames in the build directory.
# Note that the "path_prepend_ ." is useful only if the body of your
# test invokes programs residing in the initial directory.
# For example, if the programs you want to test are in src/, and this test
# script is named tests/test-1, then you would use "path_prepend_ ../src",
# or perhaps export PATH='$(abs_top_builddir)/src$(PATH_SEPARATOR)'"$$PATH"
# to all tests via automake's TESTS_ENVIRONMENT.
# Set the exit code 0 for success, 77 for skipped, or 1 or other for failure.
# Use the skip_ and fail_ functions to print a diagnostic and then exit
# with the corresponding exit code.
# Exit $?
# Executing a test that uses this file
# ====================================
#
# Running a single test:
# $ make check TESTS=test-foo.sh
#
# Running a single test, with verbose output:
# $ make check TESTS=test-foo.sh VERBOSE=yes
#
# Running a single test, with single-stepping:
# 1. Go into a sub-shell:
# $ bash
# 2. Set relevant environment variables from TESTS_ENVIRONMENT in the
# Makefile:
# $ export srcdir=../../tests # this is an example
# 3. Execute the commands from the test, copy&pasting them one by one:
# $ . "$srcdir/init.sh"; path_prepend_ .
# ...
# 4. Finally
# $ exit
ME_=`expr "./$0" : '.*/\(.*\)$'`
# We use a trap below for cleanup. This requires us to go through
# hoops to get the right exit status transported through the handler.
# So use 'Exit STATUS' instead of 'exit STATUS' inside of the tests.
# Turn off errexit here so that we don't trip the bug with OSF1/Tru64
# sh inside this function.

# export ...ENVVAR_SETTINGS...; $(SHELL) 9>&2
# in the definition of TESTS_ENVIRONMENT in your tests/Makefile.am file.
# This is useful when using automake's parallel tests mode, to print
# the reason for skip/failure to console, rather than to the .log files.
