CONTRIBUTING.md

We recommend working on a feature branch and pull request from there.

Requirements

• poetry,
• PyCharm (recommended).

Creating a feature branch

Make sure your environment contains all the updated versions of the dependencies.

From an OpenSquirrel checkout:

$ poetry shell
$ poetry install

And that you base your feature branch off an updated develop.

From a poetry shell (started from an OpenSquirrel checkout):

$ git checkout develop
$ git fetch origin
$ git pull
$ git branch <feature branch name>

Before creating the pull request

Make sure the tests and the following linters pass. From a poetry shell (started from an OpenSquirrel checkout):

$ poetry run mypy opensquirrel test --strict
$ poetry run pytest . -vv
$ poetry run ruff check --fix
$ poetry run ruff format

Setting the Python interpreter (PyCharm)

You can choose the Python interpreter from the poetry environment.

• Go to Settings > Project: OpenSquirrel > Python Interpreter.
• Click on Add Interpeter, and then select Add Local Interpreter.
• Select Poetry Environment, and then Existing environment.
• Click on ... to navigate to the Interpreter binary.

Running/Debugging tests (PyCharm)

To run/debug all tests:

• Right-click on the test folder of the Project tree.
• Click Run 'pytest' in test or Debug 'pytest' in test.

This will also create a Run/Debug Configuration.

Troubleshooting

If breakpoints are not hit during debugging:

• Go to Run/Debug Configurations.
• Add --no-cov in the Additional arguments text box.

This issue may be due to the code coverage module hijacking the tracing mechanism (check this link for a more detailed explanation).
