Standards

• Be excellent to each other
• Code coverage must be at 100% for all new code, or a good reason must be provided for why a given bit of code is not covered.
  • Example of an acceptable reason: "There is a bug in the code coverage tool and it says its missing this, but its not".
  • Example of unacceptable reason: "This is just exception handling, its too annoying to cover it".
• The code must pass the following analytics tools. Similar exceptions are allowable as in rule 2.
  • pylint --disable=C0111,W1203,R0903 --max-line-length=100 ...
  • flake8 --max-line-length=100 ...
  • mypy --ignore-missing-imports --follow-imports=skip --strict-optional ...
• All incoming information from users, clients, and configurations should be validated.
• All internal arguments passing should be typechecked whenever possible with typeguard.typechecked

Development Setup

Using poetry install from inside the repo directory:

poetry install

This will set up a virtualenv which you can always activate with either poetry shell or run specific commands with poetry run. All instructions below that are meant to be run in the virtualenv will be prefaced with (legiond)$

IDE Setup

Sublime Text 3

curl -sSL https://gitlab.com/-/snippets/2066312/raw/master/poetry.sublime-project.py | poetry run python

Development

Testing

All testing should be done with pytest which is installed with the dev requirements.

To run all the unit tests, execute the following from the repo directory:

(legiond)$  pytest

This should produce a coverage report in /path/to/dewey-api/htmlcov/

While developing, you can use watchexec to monitor the file system for changes and re-run the tests:

(legiond)$ watchexec -r -e py,yaml pytest

To run a specific test file:

(legiond)$ pytest tests/unit/test_cli.py

To run a specific test:

(legiond)$ pytest tests/unit/test_cli.py::test_cli_basics

For more information on testing, see the pytest.ini file as well as the documentation.
