This would've caught a regression that #14549 had to fix. Let's try to prevent the next regression. This requires some hackery to get namespaces initialized before the service is started; otherwise the service itself initializes namespaces, which basically ends up with a server process that runs forever. Also: in stop_service(), reset service_pid, because that's the correct thing to do. Also: add some debug statements to try to figure out a CI failure. (And leave them in place, because they might be useful for future problems). Signed-off-by: Ed Santiago <santiago@redhat.com>
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),tleaves it unchanged. If there's no leading slash,tprepends/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...
twill 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,twill invokecurlwith--data-binary @PATHand setContent-type: application/x-tar. This is useful forbuildendpoints. (To overrideContent-type, simply pass along an extra string argument matchingapplication/*): t POST myentrypoint /mytmpdir/myfile.tar application/foo 400 -
The final arguments are one or more expected string results. If an argument starts with a dot,
twill invokejqon the output to fetch that field, and will compare it to the right-hand side of the argument. If the separator is=(equals),twill require an exact match; if~(tilde),twill useexprto compare.
