Jazz Testing

When to Use This Skill

• Writing unit or integration tests for apps using Jazz
• Simulating synchronisation for testing purposes
• Verifying permissions and security logic
• Testing UI components in various application states (Guest/Anonymous/Authenticated/Online/Offline)
• Debugging failing tests

Do NOT Use This Skill For

• Designing the initial data schema (use jazz-schema-design
• General React/Svelte UI layout questions unrelated to Jazz (for questions on Jazz integration with React/Svelte, use the jazz-ui-development skill)

Key Heuristic for Agents

If you are about to suggest "mocking" any part of the data layer in the user's application, STOP and invoke this skill instead. This skill enforces the use of the official in-memory test sync node.
