Hi, I just switch to python 3.12 and I can’t launch tests on tryton\_dev. Here’s my procedure: - Cloning tryton\_dev: `hg clone ssh://hg@foss.heptapod.net/tryton/tryton tryton_dev ` - Creating virtualenv: `virtualenv .venv/trytond` - Switching to virtualenv: `source .venv/trytond/bin/activate` - Getting requirements: `.hooks/update_requirements` - Installing requirements: `pip install -r requirements.txt -r requirements-dev.txt -e trytond/ -e proteus/ ` - Trying to launch tests on specific module: `python -m unittest discover -s trytond.modules.stock.tests ` I’m getting this error: ```auto Traceback (most recent call last): File "", line 198, in _run_module_as_main File "", line 88, in _run_code File "/usr/lib/python3.12/unittest/ __main__.py", line 18, in main(module=None) File "/usr/lib/python3.12/unittest/main.py", line 104, in __init__ self.parseArgs(argv) File "/usr/lib/python3.12/unittest/main.py", line 130, in parseArgs self._do_discovery(argv[2:]) File "/usr/lib/python3.12/unittest/main.py", line 253, in _do_discovery self.createTests(from_discovery=True, Loader=Loader) File "/usr/lib/python3.12/unittest/main.py", line 160, in createTests self.test = loader.discover(self.start, self.pattern, self.top) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/unittest/loader.py", line 307, in discover raise ImportError('Start directory is not importable: %r' % start_dir) ImportError: Start directory is not importable: 'trytond.trytond.modules.stock.tests' ``` Thanks for help ! 🙂 ---

Same error: ```auto ╰─ python -m unittest discover -s trytond.modules.stock.tests Traceback (most recent call last): File "", line 198, in _run_module_as_main File "", line 88, in _run_code File "/usr/lib/python3.12/unittest/ __main__.py", line 18, in main(module=None) File "/usr/lib/python3.12/unittest/main.py", line 104, in __init__ self.parseArgs(argv) File "/usr/lib/python3.12/unittest/main.py", line 130, in parseArgs self._do_discovery(argv[2:]) File "/usr/lib/python3.12/unittest/main.py", line 253, in _do_discovery self.createTests(from_discovery=True, Loader=Loader) File "/usr/lib/python3.12/unittest/main.py", line 160, in createTests self.test = loader.discover(self.start, self.pattern, self.top) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/unittest/loader.py", line 307, in discover raise ImportError('Start directory is not importable: %r' % start_dir) ImportError: Start directory is not importable: 'trytond.modules.stock.tests' ``` ---

So it looks like `trytond` is not importable. If you can not do `import trytond.modules.stock.tests` in your python console, it is normal that the tests can not be run. ---

Try launching the tests from the `trytond` directory. Launching from the root of the repo result in the first `trytond` directory being considered as a Namespace. I haven’t looked yet what has changed between 3.11 and 3.12 so that it has this effect. ---

Indeed in Python 3.11 the toplevel directory can be imported as `)>`. For me having a `PYTHONPATH=trytond` import the right file from the top directory of the repository. ---

Indeed, working also this way in the root of the repo: ```auto PYTHONPATH=trytond:proteus python -m unittest discover -s trytond.modules.stock.tests ``` Thanks 🙂 ---
