Testing Guide

Prerequisites

The project requires ImageMagick for image processing operations. To ensure a consistent test environment, we recommend running tests inside Docker containers.

Running Tests

  1. Build and start the containers:
docker-compose up -d
  1. Run tests inside the container:
# Run all tests
docker exec cdn-golang go test ./... -v

# Run specific package tests
docker exec cdn-golang go test ./pkg/worker -v
docker exec cdn-golang go test ./service -v
docker exec cdn-golang go test ./handler -v
  1. Run tests with coverage:
docker exec cdn-golang go test ./... -coverprofile=coverage.out
docker exec cdn-golang go tool cover -html=coverage.out -o coverage.html

Test Environment

The test container includes:

  • ImageMagick (latest version, dynamically managed)
  • Redis for caching and rate limiting tests
  • MinIO for storage tests
  • Mock AWS services
  • k6 for load testing

Test Coverage

  • Unit tests with minimum 80% coverage
  • Integration tests for all endpoints
  • Performance tests using k6
  • Load testing scenarios
  • Automated API testing

Load Testing

# Run basic load test
k6 run test/performance/load_test.js

# Run stress test
k6 run --vus 50 --duration 5m test/performance/load_test.js

# Run spike test
k6 run --vus 100 --duration 10s test/performance/spike_test.js
