Ed Santiago b2e6e4829f APIv2 tests: get them passing again
In the new-Cirrus transition, APIv2 tests were inadvertently
disabled. As expected when tests get disabled, they break.

This commit fixes some failing tests, and comments out others
(with big FIXMEs) because I have neither the expertise nor
time to figure out the real problems.

The big change to test-apiv2 is due to a recently-added
test that looks for an '=' sign in json output. My '=' vs '~'
detector completely barfed on that, and there's just no
way to make it work in a bash 'case' statement. So, switch
to an 'if' with 'expr'.

And, unrelated, fix a longstanding (harmless) bug that was
issuing spurious "expected" messages to the test log; those
should've been going to the full results log.

API v2 tests

This directory contains tests for the podman version 2 API (HTTP).

Tests themselves are in files of the form 'NN-NAME.at' where NN is a two-digit number, NAME is a descriptive name, and '.at' is just an extension I picked.

Running Tests

The main test runner is test-apiv2. Usage is:

$ sudo ./test-apiv2 [NAME [...]]

...where NAME is one or more optional test names, e.g. 'image' or 'pod' or both. By default, test-apiv2 will invoke all *.at tests.

test-apiv2 connects to localhost only and via TCP. There is no support here for remote hosts or for UNIX sockets. This is a framework for testing the API, not all possible protocols.

test-apiv2 will start the service if it isn't already running.

Writing Tests

The main test function is t. It runs curl against the server, with POST parameters if present, and compares return status and (optionally) string results from the server:

t GET /_ping 200 OK
  ^^^ ^^^^^^ ^^^ ^^
  |   |      |   +--- expected string result
  |   |      +------- expected return code
  |   +-------------- endpoint to access
  +------------------ method (GET, POST, DELETE, HEAD)


t POST libpod/volumes/create name=foo 201 .ID~[0-9a-f]\\{12\\}
       ^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^ ^^^ ^^^^^^^^^^^^^^^^^^^^
       |                     |        |   JSON '.ID': expect 12-char hex
       |                     |        +-- expected code
       |                     +----------- POST params
       +--------------------------------- note the missing slash

Notes:

  • If the endpoint has a leading slash (/_ping), t leaves it unchanged. If there's no leading slash, t prepends /v1.40. This is a simple convenience for simplicity of writing tests.

  • When method is POST, the argument after the endpoint must be a series of POST arguments in the form 'key=value', separated by commas. t will convert those to JSON form for passing to the server.

  • The final arguments are one or more expected string results. If an argument starts with a dot, t will invoke jq on the output to fetch that field, and will compare it to the right-hand side of the argument. If the separator is = (equals), t will require an exact match; if ~ (tilde), t will use expr to compare.
