Thank you for showing interes in contributing to Saffier. There are many ways you can help and contribute to the project.

Reporting possible bugs and issues

It is natural that you might find something that Saffier should support or even experience some sorte of unexpected behaviour that needs addressing.

The way we love doing things is very simple, contributions should start out with a discussion. The potential bugs shall be raised as "Potential Issue" in the discussions, the feature requests may be raised as "Ideas".

We can then decide if the discussion needs to be escalated into an "Issue" or not.

When reporting something you should always try to:

  • Be as more descriptive as possible
  • Provide as much evidence as you can, something like:
    • OS platform
    • Python version
    • Installed dependencies
    • Code snippets
    • Tracebacks

Avoid putting examples extremely complex to understand and read. Simplify the examples as much as possible to make it clear to understand and get the required help.


To develop for Saffier, create a fork of the Saffier repository on GitHub.

After, clone your fork with the follow command replacing YOUR-USERNAME wih your GitHub username:

$ git clone

Install the project dependencies

$ cd saffier
$ scripts/install

Enable pre-commit

The project comes with a pre-commit hook configuration. To enable it, just run inside the clone:

$ pre-commit

Run the tests

To run the tests, use:

$ scripts/test

Because Saffier uses pytest, any additional arguments will be passed. More info within the pytest documentation

For example, to run a single test_script:

$ scripts/test tests/

To run the linting, use:

$ scripts/lint


Improving the documentation is quite easy and it is placed inside the saffier/docs folder.

To start the docs, run:

$ scripts/docs

Building Saffier

To build a package locally, run:

$ scripts/build

Alternatively running:

$ scripts/install

It will install the requirements and create a local build in your virtual environment.

Building the Saffier for release

Before releasing a new package into production some considerations need to be taken into account.

  • Changelog

    • Like many projects, we follow the format from keepchangelog.
    • Compare main with the release tag and list of the entries that are of interest to the users of the framework.
      • What must go in the changelog? added, changed, removed or deprecated features and the bug fixes.
      • What is should not go in the changelog? Documentation changes, tests or anything not specified in the point above.
      • Make sure the order of the entries are sorted by importance.
      • Keep it simple.
  • Version bump

    • The version should be in of the main package.


Once the release PR is merged, create a new release that includes:


There will be a release of the version 0.2.3, this is what it should include.

  • Release title: Version 0.2.3.
  • Tag: 0.2.3.
  • The description should be copied from the changelog.

Once the release is created, it should automatically upload the new version to PyPI. If something does not work with PyPI the release can be done by running scripts/release.
