Integration Testing with TestContainers

When to Use This Skill

Use this skill when:

• Writing integration tests that need real infrastructure (databases, caches, message queues)
• Testing data access layers against actual databases
• Verifying message queue integrations
• Testing Redis caching behavior
• Avoiding mocks for infrastructure components
• Ensuring tests work against production-like environments
• Testing database migrations and schema changes
