Performance Testing Product Service

Overview

This text provides instructions on how to set up and run performance tests for the product-service using Docker and K6.

Prerequisites

  • Docker and Docker Compose installed on your machine.
  • Basic understanding of Docker and performance testing concepts.

Setup

  1. Environment Variables: Ensure that the necessary environment variables are set. These variables are used by the services defined in docker-compose.yml. These include:

    • HOST
    • POSTGRES_DATABASE
    • POSTGRES_USERNAME
    • POSTGRES_PASSWORD
    • PGADMIN_EMAIL
    • PGADMIN_PASSWORD

    You can set these variables in your environment or use a .env file at the root of your project.

  2. Build and Start Services: Use the following command to build and start the necessary services:

    docker-compose up -d

    This will start the product-service, postgres, pgadmin, influxdb, grafana, k6, and prometheus services as defined in your docker-compose.yml.

Running Performance Tests

  1. K6 Script: Prepare your K6 script for performance testing. The script should be located in the performance_scripts directory as specified in the docker-compose.yml.

  2. Execute Test: To run the performance test, use the following command:

    docker-compose run -e VUS=<number_of_virtual_users> k6 run /scripts/performance-tests-product-service.js
  • Replace <number_of_virtual_users> with the desired number of virtual users for the test.

Monitoring and Results

  • Grafana:
    Grafana is set up to visualize the results. Access it at http://localhost:3000. Default login details are usually admin/admin.

  • InfluxDB:
    K6 sends the test results to InfluxDB, which Grafana uses as a data source.

  • Prometheus:
    Prometheus is used for monitoring; access it at http://localhost:9090.

Note

  • The performance test configuration can be adjusted in the K6 script.
  • Ensure that all services in the docker-compose.yml are properly configured and running before executing the tests.
