Raspberry PI Mocks CLI

Raspberry PI Mocks CLI imitates messages, that Raspberries send to ActiveMQ using MQTT, directly to the Kafka Cluster or via HTTP to a REST-Endpoint (bypassing amq and kafka) and allows testing without connecting sensors and real Raspberries.

Prerequisites

• JDK 8
• Maven >=3.3.9

Build

Clone Hogarama and build Habarama/raspberry-pi-mocks/raspberry-pi-mocks-cli with

mvn clean install

This will create an executable jar under Habarama/raspberry-pi-mocks/raspberry-pi-mocks-cli/target/hogarama-mock-cli.jar

Usage

java -jar hogarama-mock-cli.jar [params]

Parameters:

• -c,--configuration <arg> required: Absolute path to configuration file. The file shoud contain key-value pairs in form key=value.
• -t,--testData <arg> required: Absolute path to file with test messages.
• -d,--delayMs <arg>: Delay between publishings of single messages in ms. It overrides the parameter delayMs in configuration file. Default value is 3000.
• -host,--brokerHost <arg>: Url to AMQ broker. Overrides the parameter brokerHost in configuration file.
• -u,--brokerUsername <arg>: AMQ username. Overrides the parameter brokerUsername in configuration file.
• -p,--brokerPassword <arg>: AMQ password. Overrides the parameter brokerPassword in configuration file.
• -topic,--brokerTopic <arg>: AMQ topic name. Overrides the parameter brokerTopic in configuration file.
• -h,--help: Print help message.

Example call for AMQ:

java -jar hogarama-mock-cli.jar -t /tmp/testData.json -c /tmp/testConfig.prop --delayMs 5000

Example call for Kafka:

java -jar hogarama-mock-cli.jar -b kafka -t /tmp/testData.json -c /tmp/kafkaTestConfig.prop --delayMs 5000

Example call for REST:

java -jar hogarama-mock-cli.jar -b rest -t /tmp/testData_small.json -c /tmp/restTestConfig.prop --delayMs 5000

Example content of data file:

[{
    "sensorName" : "Pflanze",
    "type" : "wasser",
    "value" : 55.3,
    "location" : "Wien",
    "version" : 0
},
