To write Go integration tests against a live PostgreSQL database, use testcontainers-go to spin up real Docker containers during your test suite. This approach eliminates brittle mocks by validating your data access layer against an actual database instance using idiomatic Go testing patterns.

The best way to test a Go application with Redis and RabbitMQ without mocking is using testcontainers-go. It spins up real infrastructure components in Docker containers, allowing you to execute integration tests against actual caches and message queues seamlessly integrated with Go's standard testing package.

Yes, you need Docker installed and actively running on your machine to execute testcontainers-go integration tests. The framework relies on the Docker daemon to spin up real databases, caches, and message queues as lightweight containers during your Go test execution lifecycle.

Testcontainers-go integrates with standard Go testing patterns by leveraging native features like table-driven tests and t.Cleanup(). This ensures that containerized infrastructure components such as MySQL or Kafka instances are automatically torn down after your integration tests complete execution.

Yes, you can use testcontainers-go to test Kafka integrations in your Go application. It supports spinning up Kafka alongside PostgreSQL, MySQL, Redis, and RabbitMQ in Docker containers, enabling robust end-to-end integration tests for your message queue implementations.
