Logging

Testcontainers writes logs using the debug library. This allows you to enable or disable logs at runtime, and to filter logs by namespace.

The following namespaces are available:

• testcontainers*: Show all logs
• testcontainers: Show core logs
• testcontainers:containers: Show logs from containers
• testcontainers:compose: Show logs from Docker Compose
• testcontainers:build: Show build logs
• testcontainers:pull: Show image pull logs
• testcontainers:exec: Show container execution logs

Note

You can enable multiple loggers: DEBUG=testcontainers,testcontainers:exec.

---

You could for example run your tests with all Testcontainers logs enabled like this:

DEBUG=testcontainers* npm test
