SAPUI5 (Fiori front-end framework) Test

Evaluates knowledge of standard UI5 controls (like sap.m, sap.f, sap.ui.layout) and the ability to develop custom controls when needed. Testing ensures that controls are used appropriately, extend functionality cleanly, and support binding, events, and styling. It also assesses whether custom components integrate well with app lifecycle and theming.

Covers how developers use JSON, XML, Resource, and OData models and implement binding modes such as one-way, two-way, and aggregation binding. In testing, this skill ensures the developer can correctly synchronize UI and backend data, apply filters and formats, and use expression bindings efficiently. Proper data binding avoids runtime issues and ensures dynamic, real-time updates in UI elements.

Focuses on connecting SAPUI5 to backend services using OData (V2/V4), handling $filter, $expand, $batch, and response processing. Testing ensures developers can consume APIs securely and efficiently, bind data properly, handle errors gracefully, and understand the implications of asynchronous communication and service metadata usage.

This skill ensures developers can create or adjust themes using the UI Theme Designer, apply CSS overrides, and customize control appearance while maintaining Fiori standards. Testing validates consistent styling across the application, responsiveness to design tokens, and proper theme integration in custom controls, improving UX without sacrificing performance or compliance.

This skill checks the developer’s ability to identify performance bottlenecks, memory leaks, and slow bindings using Chrome DevTools, UI5 Diagnostics, and logging. Testing scenarios might involve slow-rendering controls, poor aggregation handling, or large datasets. Candidates must show they can troubleshoot intelligently and implement lazy loading, efficient event handling, and model reuse.

This includes mastery over the MVC architecture, controller/view lifecycle, event handling, and view types (XML, JSON, JS). Testing these concepts confirms the developer can build clean, maintainable apps that separate business logic from UI concerns. It also ensures views are structured correctly and controllers are modular, reusable, and aligned with SAP development best practices.

This skill reflects the ability to work with metadata-driven UI components like SmartTable and SmartForm, commonly used with Fiori Elements and CDS annotations. Testing evaluates whether candidates understand how to use annotations to drive behavior, apply filters, or generate UI automatically. It's essential for building maintainable apps that scale with backend model changes without manual UI updates.

This skill focuses on managing intra-app navigation via hash-based routing defined in manifest.json, including dynamic routes, nested navigation, and event handling. Testing verifies that navigation is smooth, consistent, and bookmarkable. It also checks if developers can handle pattern matching, parameter passing, and target resolution within multi-view applications or tabbed interfaces.

As SAPUI5 evolves, support for ES6 and TypeScript improves code maintainability and reliability. This skill tests the ability to structure apps using modules, import/export constructs, and typed classes/interfaces. Evaluation includes proper use of module loading strategies and bundling. It ensures apps are modern, scalable, and ready for large-team development.

Covers managing multilingual support using i18n resource bundles and ensuring UI compliance with accessibility standards (e.g., ARIA roles, screen reader support). Testing verifies if the app handles locale switching, labels inputs for assistive tech, and doesn't hardcode strings. It’s critical for building globally usable, inclusive enterprise applications.

This skill tests proficiency in using QUnit and OPA5 for unit and integration testing. Developers must show they can write tests to validate UI behavior, user flows, and service responses. Testing this skill ensures reliability, reduces regressions, and promotes clean, test-driven development practices across UI5 projects.

This includes deploying UI5 apps on SAP BTP (via HTML5 Repo, AppRouter) and integrating with the Fiori Launchpad. Testing ensures apps are deployable across environments, use destinations correctly, and function as intended in FLP tiles or standalone setups. It’s key for end-to-end delivery and runtime readiness.

Tests understanding of CSRF protection, input sanitization, session handling, and role-based UI visibility. Developers should design apps that prevent data leaks, respect user roles, and handle tokens or backend errors gracefully. Testing this ensures apps are secure, audit-compliant, and production-ready in enterprise landscapes.

Ensures the developer adheres to SAP’s UX guidelines—simplicity, responsiveness, and role-based access. Testing covers use of layout controls, Fiori floorplans, and design-consistent behavior. This skill is essential for apps that must pass UX audits and deliver consistent experiences across devices, ensuring stakeholder satisfaction and user adoption.
