Contributing

The keywords in this library are based on some of the methods available in eclipse paho client library. If you’d like to add keywords, see instructions on creating/updating libraries for Robot Framework.

The tests are in tests folder and make use of Robot Framework itself. They need two local MQTT brokers: one without authentication, used by most tests, and one that requires a username and password. Both are defined in docker-compose.yml. They need Docker Engine 25 or later. Start them, run the tests, and stop them when you are done:

docker compose up --wait
robot -P src tests
docker compose down

The test credentials live in mosquitto/passwd_file. To regenerate it, run scripts/gen-passwd.sh.
