RequestGenerator is created to help stress test the entire distributed system with various loads.

Example/default scenario: 100 different users each submitting single booking requests for a single dental office within a time-interval of ten seconds.

• Install Java JDK 8 or above
• Install Maven 3.5 or above
• Install MQTT Broker (e.g. Mosquitto) and run it locally on port 1883
  • For a helpful tutorial refer to Steve's Internet Guide

Make sure to have the Booking component running before running the RequestGenerator.

1. Clone repository to your machine
2. Open a terminal window (e.g. Command Prompt) and move to the root folder of the repository. Enter command mvn clean install This will create a target folder.
3. To ensure that installation was successful, check target folder for RequestGenerator.jar file.
4. Move to target folder and enter command java -jar RequestGenerator.jar. This will enable the RequestGenerator to start publishing requests to the MQTT Broker.

• the number of requests made per user, change the NUMBER_OF_REQUESTS_PER_USER variable.
• the topic to publish requests to, change the TOPIC variable.
• the dentist office to make booking requests to, change the DENTIST_ID variable.
