Matt Heon e04668c8ca Match output of Compat Top API to Docker
We were only splitting on tabs, not spaces, so we returned just a
single line most of the time, not an array of the fields in the
output of `ps`. Unfortunately, some of these fields are allowed
to contain spaces themselves, which makes things complicated, but
we got lucky in that Docker took the simplest possible solution
and just assumed that only one field would contain spaces and it
would always be the last one, which is easy enough to duplicate
on our end.

Fixes #23981

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

Never, ever, ever, seriously EVER exit from a test. Just don't. That skips cleanup, and leaves the system in a broken state.

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(s) after the endpoint may be a series of POST parameters in the form 'key=value', separated by spaces: t POST myentrypoint 200 ! no params t POST myentrypoint id=$id 200 ! just one t POST myentrypoint id=$id filter='{"foo":"bar"}' 200 ! two, with json t POST myentrypoint name=$name badparam='["foo","bar"]' 500 ! etc... t will convert the param list to JSON form for passing to the server. A numeric status code terminates processing of POST parameters. ** As a special case, when one POST argument is a string ending in .tar, .yaml, or .json, t will invoke curl with --data-binary @PATH and set Content-type as appropriate. This is useful for build endpoints. (To override Content-type, simply pass along an extra string argument matching application/*): t POST myentrypoint /mytmpdir/myfile.tar application/foo 400 ** Like above, when using PUT, t does --upload-time instead of --data-binary

  • 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.

  • If your test expects curl to time out: APIV2_TEST_EXPECT_TIMEOUT=5 t POST /foo 999
