MQTTLibrary is a Robot Framework library that provides keywords for testing on MQTT brokers. MQTT is a lightweight protocol for machine-to-machine communication, typically used for IoT messaging. This library uses the paho client library published by eclipse project.
MQTTLibrary can be installed using pip:
pip install robotframework-mqttlibrary
You can also install it from the source distribution by running:
python setup.py install
You may need to run the above command with administrator privileges.
Import the library:
*** Settings ***
Library MQTTLibrary
Connect to the broker, publish and disconnect:
*** Test Cases ***
Publish
Connect 127.0.0.1
Publish topic=test/mqtt_test message=test message
[Teardown] Disconnect
Connect to the broker, subscribe and validate that a message is received:
*** Test Cases ***
Subscribe and Validate
Connect 127.0.0.1
Subscribe and Validate topic=test/mqtt_test qos=1 payload=test
[Teardown] Disconnect
Keyword documentation is available at: http://randomsync.github.io/robotframework-mqttlibrary.
Also look at tests
folder for examples.
For general information about using test libraries with Robot Framework, see Robot Framework User Guide.
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 are run automatically through travis when code is pushed to a branch. When run locally, these tests rely on locally running mqtt brokers. We need 2 running brokers, one without auth that is used by most of the tests, and the other one with auth (configuration file is provided). You'll need to start them before running the tests. You can then run the tests locally:
docker pull eclipse-mosquitto docker run -d -p 1883:1883 eclipse-mosquitto docker run -d -p 11883:1883 -p 9001:9001 -v $(pwd)/mosquitto:/mosquitto/config eclipse-mosquitto robot -P src tests
Make sure to stop the docker container when it is no longer needed.
