tappy should be easy to contribute to. If anything is unclear about how to contribute, please submit an issue on GitHub so that we can fix it!


Fork tappy on GitHub and submit a Pull Request when you’re ready.

The goal of tappy is to be a TAP-compliant producer and consumer. If you want to work on an issue that is outside of the TAP spec, please write up an issue first, so we can discuss the change.


tappy uses the built-in venv module.

$ git clone
$ cd tappy
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -r requirements-dev.txt
$ # Edit some files and run the tests.
$ pytest

The commands above show how to get a tappy clone configured. If you’ve executed those commands and the test suite passes, you should be ready to develop.
