Hi! Is there an easy way to run ansible unittests and integration tests locally before push? Some kind of preconfigured docker container with all deps installed? ---

Yes, please see [https://docs.ansible.com/ansible/latest/dev\_guide/testing.html](https://docs.ansible.com/ansible/latest/dev_guide/testing.html) for more detail. In short: ansible-test units --docker default /path/to/unit/test\_something.py ---

I’ve tried it with different shells (bash and fish), different python envs (MacOS built-in and virtual env with python 2.7 and 3.6) with no luck. All comes down to this: ` bash-3.2$ ./bin/ansible-test sanity --test pep8 Sanity check using pep8 Traceback (most recent call last): File “./bin/ansible-test”, line 15, in lib.cli.main() File “/Users/andy/workspace/contrib/ansible/test/runner/lib/cli.py”, line 108, in main args.func(config) File “/Users/andy/workspace/contrib/ansible/test/runner/lib/sanity/ **init**.py”, line 113, in command\_sanity result = test.test(args, targets) File “/Users/andy/workspace/contrib/ansible/test/runner/lib/sanity/pep8.py”, line 66, in test stdout, stderr = run\_command(args, cmd, capture=True) File “/Users/andy/workspace/contrib/ansible/test/runner/lib/util.py”, line 366, in run\_command cmd\_verbosity=cmd\_verbosity, str\_errors=str\_errors) File “/Users/andy/workspace/contrib/ansible/test/runner/lib/util.py”, line 432, in raw\_command process = subprocess.Popen(cmd, env=env, stdin=stdin, stdout=stdout, stderr=stderr, cwd=cwd) File “/Users/andy/.pyenv/versions/3.6.8/lib/python3.6/subprocess.py”, line 729, in **init** restore\_signals, start\_new\_session) File “/Users/andy/.pyenv/versions/3.6.8/lib/python3.6/subprocess.py”, line 1364, in \_execute\_child raise child\_exception\_type(errno\_num, err\_msg, err\_filename) OSError: [Errno 7] Argument list too long: ‘/Users/andy/.local/share/virtualenvs/ansible-FTkjm-xR/bin/python’ ` So, I thought, maybe there is a preconfigured docker environment, that just works… ---

I think the guide needs some polishing… It’s missing some statements about requirements.txt (and there are tons of them!) import for instance. I have an issue with `source hacking/env-setup` - don’t actually know what it is actually, maybe it is in conflict with brew ansible package, which uses some environment too… I’ve ended up creating a small docker-compose script to run everything (including python env and this hacking stuff) inside container, so no collisions would be possible. Maybe it will be useful in some way: [https://github.com/astorath/ansible-test](https://github.com/astorath/ansible-test)
