SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a structured approach to using Testcontainers for Go to run integration tests with Docker containers, reducing flaky tests and simplifying setup and cleanup.

Core Features & Use Cases

  • Pre-configured modules: Access 62+ ready-to-use modules for databases, queues, cloud services, and more to speed test environments.
  • Simplified container lifecycle: Start, connect, and tear down containers with consistent APIs and cleanup patterns.
  • Multi-service scenarios: Build integration tests across databases, caches, and messaging systems in isolated environments.

Quick Start

Install the required Go packages, initialize a testcontainers-go workflow, and start a container cluster using the modules. For example, start a PostgreSQL container using the postgres module and retrieve a connection string for your tests.

FAQPage Schema
How do I provision Docker containers for Go integration testing?

To provision Docker containers for Go integration testing, you use a framework that automates container lifecycle management, providing pre-configured modules for databases and queues to ensure reproducible test environments.

What is the best way to reduce flaky tests when using Docker in Go tests?

The best way to reduce flaky Docker tests in Go is to enforce reliable wait strategies and consistent cleanup patterns, ensuring containers are fully initialized before tests run and properly torn down afterward.

Can I run multi-service integration tests with databases and queues in Go?

Yes, you can build multi-service integration tests across databases, caches, and messaging systems in isolated environments using pre-configured modules that simplify container startup and connectivity.

Does testcontainers-go support pre-configured modules for cloud services?

Yes, it provides access to over 62 ready-to-use modules for databases, queues, and cloud services, allowing you to quickly speed up test environment setup without manual Docker configuration.

How do I get a database connection string from a PostgreSQL container in Go tests?

You start a PostgreSQL container using the postgres module within your test workflow, which automatically manages the container lifecycle and allows you to retrieve the connection string for your tests.

Why do my Go integration tests fail when Docker containers are not ready?

Integration tests fail when containers are not fully initialized, but you can prevent this by applying comprehensive wait strategies that ensure services are ready to accept connections before tests execute.
