I would like to run all my django tests using mercurial's precommit hook. Whenever a test fails the commit will be aborted.
The goal is to block build-breaking commits as often as possible.
edit: Ended up using the external script route. Here is the reletant portion of my hgrc:
[hooks]
precommit = python ./pinax/projects/lgr/manage.py test lgr_photos --verbosity=0 --noinput
commit = hg push
Here is my progress on the hook function:
from os.path import join, dirname
import sys
from django.core.management import call_command
def hook(ui, repo, **kwargs):
project_path = join( dirname(repo.path), 'pinax', 'projects')
sys.path.insert(0, project_path)
from lgr.manage import *
output = call_command('test', verbosity=0, interactive=False)
#ui.warn(output)
What am I doing wrong here?
PS - It's giving a HUGE error traceback, which is included in it's entirety below

If you want to run a test case class which has the path <module_name>/tests/test_views.py , you can run the command python manage.py test <module_name>. tests. test_views.
If you want to manually run all pre-commit hooks on a repository, run pre-commit run --all-files . To run individual hooks use pre-commit run <hook_id> . The first time pre-commit runs on a file it will automatically download, install, and run the hook.
The preferred way to write tests in Django is using the unittest module built-in to the Python standard library. This is covered in detail in the Writing and running tests document. You can also use any other Python test framework; Django provides an API and tools for that kind of integration.
The pre-commit hook is run first, before you even type in a commit message. It's used to inspect the snapshot that's about to be committed, to see if you've forgotten something, to make sure tests run, or to examine whatever you need to inspect in the code.
It looks like Mercurial's way of importing modules is clashing with Django's somehow.
Before trying to dive in and sort that out, is there any reason to not just run the tests with the normal command?
[hooks]
precommit.runtests = python manage.py test
