event-sourcing-tests

Tests for an event-sourced system verify replay determinism, snapshot equivalence, and version-evolution correctness - without them, the event log silently drifts from the rebuilt state.

When to use

• Domain model is event-sourced (orders, accounts, inventory).
• Audit / compliance requirements demand event log as system of record.
• Adding a new event type or changing payload schema - retro-compat tests are mandatory.
