`podman -h` currently returns an error:
`Error: pflag: help requested`
This bug was introduced in 44d037898ebc, the problem is that we wrap the
error and cobra lib checks with `==` for this one and not errors.Is().
I have a PR upstream to fix this but for now this also works.

- Look for and prevent lower-case arg descriptions:
podman cmd [arg]
- Look for and prevent optional-mandatory misordering:
podman cmd [ARG] ARG
- Tighter whitespace checks (and fix podman pod ps)
- simplify a no-longer-necessary mess! #8635 fixed the
horrible "CONTAINER | IMAGE" strings (with spaces),
so there's no longer a need to special-case those.
The one-extra-arg check is now much cleaner.
Minor refactoring.

Problem: the system test 'is()' checker was poorly thought out.
For example, there is no way to check for inequality or for
absence of a substring.
Solution, step 1: introduce new assert(), copied almost verbatim
from buildah, where it has been successful in addressing the
gaps in is().
The logical next step is to search the tests for 'die' and
for 'run', looking for negative assertions which we can
replace with assert(). There were a lot, and in the process
I found a number of ugly bugs in the tests themselves. I've
taken the liberty of fixing these.
Important note: at this time we have both assert() and is().
Replacing all instances of is() would be impossible to review.

Current error messages are really awful, and cause great
suffering every time someone adds a new subcommand. Let's
see if these are better.

There exists a unit test to ensure that shell completion functions are
defined. However there was no check about the quality of the provided
shell completions. Lets change that.
The idea is to create a general test that makes sure we are suggesting
containers,pods,images... for the correct commands. This works by
reading the command use line and checking for each arg if we provide
the correct suggestions for this arg.
It includes the following tests:
- flag suggestions if [options] is set
- container, pod, image, network, volume, registry completion
- path completion for the appropriate arg KEYWORDS (`PATH`,`CONTEXT`,etc.)
- no completion if there are no args
- completion for more than one arg if it ends with `...]`
The test does not cover completion values for flags and not every arg KEYWORD
is supported. This is still a huge improvement and covers most use cases.
This test spotted several inconsistencies between the completion and the
command use line. All of them have been adjusted to make the test pass.
The biggest advantage is that the completions always match the latest
command changes. So if someone changes the arguments for a command this
ensures that the completions must be adjusted.

Want to have man pages match commands, since we have lots of printed

Options in --help.

Add new system check confirming that "podman foo -l arg"
throws an error; and fix lots of instances where code
was not doing this check.
I'll probably need to add something similar for --all but
that can wait.

info, images, run, networking tests: remove some skip_if_remote()s
that were added in the varlink days. All of these tests now seem
to work with APIv2.
help test: check that first output line from 'podman --help'
is the program description (regression check for #7273).
load test: clean up stray images, rewrite test to make it conform
to existing convention. In the process, discover and file #7337
exec test (and networking): file #7360, and add FIXME comment
to skip()s suggesting evaluating those tests once that is fixed.
pod test: now that #6328 is fixed, use 'podman pod inspect --format'
instead of relying on jq
Various other tests: add an explanation of why test is disabled
so we can more easily distinguish "this will never be meaningful
under remote" vs "hey, doesn't work for now, but maybe someday".

The error messages from the 'podman xxx --help' cross-check
test are unhelpful, and cause much wasted time when they trigger.
Solution: instead of using the built-in exit-status check
in run_podman, do an explicit check outside of run_podman.
This lets us die() with a custom, hopefully useful, message.

New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.
flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.
While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).
I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.

...plus a few others. And fixes to actual parsing.
If a command's usage message includes '...' in the
argument list, assume it can take unlimited arguments.
Nothing we can check.
For all others, though, the ALL-CAPS part on the
right-hand side of the usage message will define
an upper bound on the number of arguments accepted
by the command. So in our 'podman --help' test,
generate N+1 args and run that command. We expect
a 125 exit status and a suitably helpful error message.
Not all podman commands or subcommands were checking,
so I fixed that. And, fixed some broken usage messages
(all-caps FLAGS, and '[flags]' at the end of 'ARGS').
Add new checks to the help test to prevent those in
the future.
Plus a little refactoring/cleanup where necessary.

Now that we've agreed that usage messages should match
what the user typed, confirm it. IOW 'podman foo --help'
should not issue a usage message for 'podman container foo'.
Fix one broken instance, 'unpause'.

in cases where commands require input and we dont provide it, we often would segv. This can be attributed in many cases to the subcommand not picked up the cobra Args attribute or neither had them.

If a usage message is of the form '... [flags] ARGNAME',
where ARGNAME is all-caps and not in brackets, it must
be a required argument. Try running podman subcommand
without ARGNAME, and make sure that podman bails out
with an informative message. (Since this message is
freeform in each subcommand, not Cobra-generated,
we have a lot of possible variations to check for).
Fix podman login/logout Use messages to indicate that
REGISTRY is now optional (as of #5233).
This test has actually been in place for over a year but
due to a typo on my part -- a missing space -- it was
not being run. "For want of a space, much testing was lost".

Unless specified otherwise by --all, --latest or via arguments, list all
running containers. This matches the behaviour of Docker and is also
illustrated in the man pages where containers and options are marked to
be optional.

podman-remote now supports rm! That's what we needed to start
running BATS tests.
Although most tests don't actually work, some do, and maybe
the rest will start working over time. For now, disable them.
The only significant difference found is that podman-remote
strips fractional seconds from timestamps in JSON output.
Probably not something worth caring about.

New:
- podman exec
- podman load (requires #2674)
- CLI parsing (regression test for #2574)
Improved:
- help: test "podman NoSuchCommand", and subcommands
- help: test "podman cmd" without required args
- pod: start with --infra=false; this allows running rootless
- log: also run 'logs' after container is run
- log: test -f with two containers
Also, use helpful descriptions for skip_if_rootless
Tested on f29, root and rootless. As soon as podman-remote
supports rm, I'll start testing that too.

- document a recommended convention for fail-fast tests
- document the requirement for jq. (And, add a fail-fast
test for its presence; remove the duplicated checks
in subtests)
- add further sanity checks to 'help' test. Add missing
documentation. Remove a no-longer-needed workaround for
usage-message bug fixed in #2486
- add a documented TEMPLATE
- and, since we're at 1.1, enable 'Remote API' check in
version test
- better diagnostics in setup/teardown; add vim filetype hint;
better formatting of actual-vs-expect errors
- new pod-top, logs, build tests
- improve error messages
- add $IMAGE alias for ridiculous $PODMAN_TEST_IMAGE_FQN
- final cleanup, in prep for merge

Initial attempt at writing a framework for podman system tests.
The idea is to define a useful set of primitives that will
make it easy to write actual tests and to interpret results
of failing ones.
This is a proof-of-concept right now; only a small number of
tests, by no means comprehensive. I am requesting review in
order to find showstopper problems: reasons why this approach
cannot work. Should there be none, we can work toward running
these as gating tests for Fedora and RHEL8.
