Responsibility

  • Defines the components of a rocket.
  • Provides functions for creating and managing rocket components.

Scope

  • Component definitions (e.g., body tube, nose cone, fins, motor, parachute).
  • Component creation and management functions.

Test Suite Overview

  • Tests should cover component creation and management.

Decisions & Potential Gotchas

  • Component definitions should be well-defined and documented.
  • Component management logic should be robust.
