### Overview
#
# Testing is conducted with this script, in the source tree root, using the
# tests in tests/.
#
# Basically, tests follow the format:
#
# - tests/[utility].[number].test
# Test #[number]. This is an executable file (typically a script).
# - tests/[utility].[number].expected
# This is the expected standard output of test #[number].
#
# This script runs the executable [utility].[number].test and the following
# file is written during testing:
#
# - tests/[utility].[number].output
# The actual standard output from test #[number].
#
# If the actual standard output from the test differs from the expected
# standard output, the testing ends, showing the difference.
set -e
alias emit="printf '%s: %s\n' '$0' \"\$1\""
export PATH="$PATH:./build/bin/"
if strcmp '' "$1"; then
printf 'Usage: %s [utilities...]\n' "$0" >&2
exit 64 # sysexits.h(3) EX_USAGE
fi
### Details
while ! strcmp '' "$1"; do # $1 refers to the given utility
# Tests are called [utility].[number].test. Tests are numbered from 1 with no
# leading zeroes in the numbers, so (for example) scrut(1)'s first three tests
# are scrut.1.test, scrut.2.test, and scrut.3.test. Tests are run sequentially
# in the numbered order.
i=1
while scrut -e "$1.$i.test"; do # $i refers to the test number
emit "$1.$i.test: Running test..."
# A test is an executable file. This runs each test for given utilities
# and writes the standard output from the test to [utility].[number].output,
# then uses diff(1p) (with the "-u" option) to highlight differences between
# the actual output and the expected output, which is located at
# [utility].[number].expected. If there are no differences none are shown and
# testing continues.
# $1.$i.test is the same as [utility].[number].test
./"$1.$i.test" \
| mm -o "$1.$i.output" -o - \
| diff -u - "$1.$i.expected" \
|| emit '$1.$i.test: Test passed.\n'
# "set -e" terminates on an unsuccessful exit
# The ideal output of this script is no output at all and each
# [utility].[number].output written matching its associated
# [utility].[number].expected.

# This test is theoretically Linux-dependent; write(2) should return -1 on
# error.
# Right now dj(1) interprets the return value of write(2) as the amount of
# bytes written. This can decrement the stored quantity of bytes written,
# which is an int, so doesn't underflow but goes negative. dj(1) tries to
# again to write(2) if an error occurs in which no bytes are written, so in
# total two write(2)s are attempted and so the written byte quantity is -2.
# This is a bug and will change, but for now is at least documented.
