DB Infrastructure Mocks

When to Use

• Integration dependencies (RDBMS, Redis, MongoDB) prevent running tests or local development and you need safe, testable alternatives.

Responsibilities

• Locate where clients and connections are constructed and consumed (database/ package).
• Propose interface-based seams and minimal mock implementations.
• Provide migration path and verification steps so production behavior remains unchanged.

Rules

• Prefer small interfaces and constructor injection over large refactors.
• Make tests deterministic and avoid network calls.
• Provide unit and integration verification steps for any change.
