Does this skill help prevent resource leaks?

Yes, it provides standardized patterns for container cleanup using test lifecycle hooks to ensure Docker resources are released even if tests fail.

Do I need Docker to use this skill?

Yes, Testcontainers requires a running Docker or Podman environment to spin up the necessary service containers during test execution.

Is it better to use Testcontainers than mocking?

For integration testing, yes. It allows you to test against real versions of your dependencies, catching compatibility bugs that mocks often miss.

How many services are supported?

There are over 62 pre-configured modules available, including popular choices like PostgreSQL, Redis, Kafka, Elasticsearch, and LocalStack.
