All development is currently done against Python 3.5 (the latest available in Ubuntu 16.04), and all CI tests are ran against version 2.7, 3.5, and 3.6.


Bootstrapping your development environment is easy! Once you set up whatever virtualenv or container or VM that you want to do development in, there’s one command to run:

make develop

This will install all of the pip requirements in and install Posty into your environment in ‘editable mode’. Editable mode means that Posty will be installed into your env as if it were any other package, but any changes you make to the source code will be instantly reflected in the CLI binary.


To run the test suite, simply run make test. This will run:

  1. pycodestyle (formerly pep8)
  2. flake8
  3. pytest
