a wide range of human and artificial life, it is very difficult to
test the shell thoroughly. For this purpose, the Test subdirectory
exists. It consists of a driver script (ztst.zsh) and various test
files (*.ztst) in a format which is described in cd.ztst, which acts
files (*.ztst) in a format which is described in 50cd.ztst, which acts
as a template. It is designed to make it easy to provide input to
chunks of shell code and to test the corresponding standard output,
error output and exit status.

# This file serves as a model for how to write tests, so is more heavily

# of the distribution, which must be writable. They should end with
# the suffix `.ztst': this is not required by the test harness itself,
# but it is needed by the Makefile to run all the tests.
# Blank lines with no other special meaning (e.g. separating chunks of
# code) and all those with a `#' in the first column are ignored.
# All section names start with a % in the first column. The names
# must be in the expected order, though not all sections are required.
# The sections are %prep (preparatory setup: code executed should return
# status 0, but no other tests are performed), %test (the main tests), and
# %clean (to cleanup: the code is simply unconditionally executed).
#
# Literal shell code to be evaluated must be indented with any number
# of spaces and/or tabs, to differentiate it from tags with a special
# meaning to the test harness. Note that this is true even in sections
# where there are no such tags. Also note that file descriptor 9
# is reserved for input from the test script; if ZTST_verbose is set,
# output is sent to the original stdout via fd 8. Option settings
# are preserved between the execution of different code chunks;
# initially, all standard zsh options (the effect of `emulate -R zsh')
# are set.
%prep
# This optional section prepares the test, creating directories and files
# and so on. Chunks of code are separated by blank lines (which is not
# necessary before the end of the section); each chunk of code is evaluated
# in one go and must return status 0, or the preparation is deemed to have
# failed and the test ends with an appropriate error message. Standard
# output from this section is redirected to /dev/null, but standard error
# is not redirected.

%test
# This is where the tests are run. It consists of blocks separated
# by blank lines. Each block has the same format and there may be any
# number of them. It consists of indented code, plus optional sets of lines
# beginning '<', '>' and '?' which may appear in any order. These correspond
# to stdin (fed to the code), stdout (compared with code output) and
# stderr (compared with code error output) respectively. These subblocks
# may occur in any order, but the natural one is: code, stdin, stdout,
# stderr.
#
# The rules for '<', '>' and '?' lines are the same: only the first
# character is stripped, with subsequent whitespace being significant;
# lines are not subject to any substitution unless the `q' flags (see
# below) is set.
#
# Each chunk of indented code is to be evaluated in one go and is to
# be followed by a line starting (in the first column) with
# the expected status returned by the code when run, or - if it is
# irrelevant. An optional set of single-letter flags follows the status
# or -. The following are understood:
# d Don't diff stdout against the expected stdout.
# D Don't diff stderr agsinst the expected stderr.
# q All redirection lines given in the test script (not the lines
# actually produced by the test) are subject to ordinary quoted shell
# expansion (i.e. not globbing).
# This can be followed by a `:' and a message describing the
# test, which will be printed if the test fails, along with a
# description of the failure that occurred. The `:' and message are
# optional, but highly recommended.
# Hence a complete status line looks something like:
# 0dDq:Checking whether the world will end with a bang or a whimper
#
# If either or both of the '>' and '?' sets of lines is absent, it is
# assumed the corresponding output should be empty and it is an error if it
# is not. If '<' is empty, stdin is an empty (but opened) file.
