A new hands-on tutorial is now available to accompany the Devtoberfest session UI5 Middleware FE Mockserver in Practice — Setup, Use Cases, Live Coding. It’s a guided, step-by-step journey showing how to use @sap-ux/ui5-middleware-fe-mockserver productively with Fiori Elements and beyond covering setup, data strategies, actions, multi-service scenarios, tenant isolation, offline E2E testing with wdi5, and recording real backend traffic for offline replay.
Why this tutorial matters
The mockserver lets you develop and test Fiori apps locally and offline with metadata-accurate data, predictable scenarios, and action implementations without waiting on backend availability. The tutorial distills best practices into small exercises you can run immediately.
What you’ll learn (exercise overview)
ExerciseFocusKey Takeaways1. Basic Setup – Generated DataZero-config mock data from metadataStart fast; remove backend proxy for true offline; draft simulation2. Custom JSON DataPredictable datasetsStable testing scenarios; relationships; consistent IDs and referential keys3. JavaScript LogicDynamic data + actionsImplement getInitialDataSet and executeAction; validations; latency simulation4. Multiple ServicesBookshop + ReviewsMicroservices-style config with distinct metadata and datasets5. Cross-Service CommunicationService-to-service flowsTrigger operations across services (e.g., promotion creates review)6. Context-Based IsolationTenant-specific dataUse ?sap-client= to switch tenants; optional tenant-aware logic7. Error HandlingBusiness and system errorsReturn 400/404/422/500/501 with helpful messages for UI testing8. Offline E2E Testingwdi5 + mockserverReliable CI-ready tests without backend dependency9. Record Live ODataui5-middleware-odata-recorderCapture real backend traffic → generate mock datasets for offline replay
How to get started
The tutorial is available in the README and is designed to run locally in small, focused apps per exercise. You’ll find commands, file locations, and ready-to-run configurations.

Session context
This tutorial was introduced in the Devtoberfest session UI5 Middleware FE Mockserver in Practice — Setup, Use Cases, Live Coding, featuring live coding around configuration, data providers, offline mode, tenant-specific datasets with fallbacks, cross-service scenarios, and wdi5 integration for robust E2E tests. You can rewatch the session now.
