Robot-server with plone 6.0.0a4 minimal setup not working

Plone Support
#1

Prerequisite:

  • Python 3.9 venv
  • setuptools==62.1.0 and zc.buildout==3.0.0rc3 installed

This is my minimal buildout to get a robot-server script:

[buildout]
extends =
    http://dist.plone.org/release/6-latest/versions.cfg


parts += testserver


[testserver]
recipe = zc.recipe.egg
eggs =
    plone.app.robotframework [test]
scripts =
    robot-server

[versions]
plone.app.robotframework = 2.0.0a6

However if i start the server via:

$ ./bin/robot-server plone.app.testing.layers.PLONE_WSGISERVER -vvvv --debug

...
16:18:31 [ wait ] Set up plone.testing.zope.WSGIServer
INFO:Zope:Ready to handle requests
16:18:31 [ wait ] Set up plone.app.testing.layers.Plone:WSGIServer
16:18:31 [ ready ] Started Zope robot server
XMLRPC: http://127.0.0.1:49999

I'm not able to get anything from that instance. respectively I get a 501:

Error response
Error code: 501

Message: Unsupported method ('GET').

Error code explanation: HTTPStatus.NOT_IMPLEMENTED - Server does not support this operation.

I tried several other options, like creating my own mixin or use the volto testing layers (./bin/robot-server plone.app.robotframework.testing.VOLTO_ROBOT_TESTING -vvvv --debug). Same result.

It starts up, testing layer seems to get applied as well. But still 501.
Any help is really appreciated :blush:

I know I'm using the latest versions of everything and you guys are working hard on plone 6. Maybe somebody hat the same issues or I'm missing something obvious?

Thanks, but I know on which port the service is running. The service itself replies with 501 in the browser and in the logs. I can change the port, but I do get the same result.

the only way for me to run robot tests:

start Server:

ZSERVER_HOST=127.0.0.1 ZSERVER_PORT=50003 bin/robot-server --reload-path src dev.robotcheck.testing.DEV_ROBOTCHECK_ACCEPTANCE_TESTING

start the Test:

ZSERVER_HOST=127.0.0.1 ZSERVER_PORT=50003 TMPDIR=./tmp bin/robot src/dev/robotcheck/tests/robot/test_example.robot

site note: the TMPDIR is necessary to run the test in Browsers, which are installed via snap in ubuntu. i'am on ubunut 22.04

all other fails, e.g.:

./bin/test --all -m  dev.robotcheck -t test_example.robot
or 
TMPDIR=/tmp ./bin/test --all -m  dev.robotcheck -t test_example.robot

when I do bin/robot-server -v Products.CMFPlone.testing.PRODUCTS_CMFPLONE_ROBOT_TESTING

Does anyone have an idea?

Turns out it was a multiprocessing problem.

Setting ENV var disable_proxy=1 solved my problem (see Multiprocessing causes Python to crash and gives an error may have been in progress in another thread when fork() was called - Stack Overflow) :

disable_proxy=1 bin/robot-server Products.CMFPlone.testing.PRODUCTS_CMFPLONE_ROBOT_TESTING
