### 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.

||||

### 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.

||||

|
||||

|
||||
|
||||
# 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
|
||||

|

| 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.
