C_FIORD_2502 SAP Certified Associate - SAP Fiori Application Developer Questions and Answers

ResponsiveFlowLayoutallows content towrap and flowaccording to screen size and available space:

Preferred for building responsive UI layoutswithout tables.

Supports multiple rows and automatic adjustment of elements.

SAPUI5 Layout Control Reference:

“ResponsiveFlowLayout arranges controls in rows, wrapping them depending on the available width.”

Grid layout is rigid, and Vertical/Horizontal layouts are not responsive.

OPA5 (One Page Acceptance)testing framework is used for:

End-to-end integration testingof SAPUI5 apps.

Verifyingnavigation, routing, and view transitionsusing test cases written in Given-When-Then format.

SAPUI5 Testing Guide:

“OPA tests simulate full user interactions, including navigation, and validate that applications behave as expected.”

QUnit is for unit tests. Sinon is a mocking library. Mock server simulates backend but doesn’t test navigation logic.

assert.strictEqual() checks bothvalue and typeusingstrict equality (===)in JavaScript.

0 === -0 →true

Others fail due to type mismatch or value mismatch.

QUnit API Reference:

“Use strictEqual for strict equality. It compares both value and type.”

SAP Fiori elements provide:

Design compliancewith SAP Fiori UX guidelines.

Reduced costby minimizing custom code.

MVCarchitecture separates concerns:

Modelhandles data.

Viewdisplays data.

Controllerhandles logic.

Advantages:

Views can be changedindependently from business logic (Controller).

Multipleviewscan present the same model data differently.

SAP MVC Documentation:

“MVC enables separation of concerns, easier debugging, and reusability of components.”

Quick coding is not inherently a feature of MVC, and transport independence is handled via SAP tooling, not MVC itself.

QUnitfollows theAAApattern:

Arrange: Prepare test data/setup.

Act: Perform the operation.

Assert: Validate the result.

SAP Testing Guidelines:

“The Arrange-Act-Assert (AAA) pattern is fundamental to unit testing logic with QUnit.”

B is the pattern for OPA5 (behavioral testing), not QUnit.

In QUnit:

TheActis the operation you’re testing — in this case, pressing a button (press("1")).

Arrangeis setting up the object.

Assertis comparing the output.

QUnit Testing Concepts:

“Act corresponds to executing the logic you want to test (e.g., method calls).”

Extension points allow app developers to inject custom UI or logic into standard apps:

Custom column: Add additional columns to tables.

Custom section: Extend the Object Page with new sections.

Tiles are linked viaTarget Mappings, which define:

Semantic object + Actioncombination.

This routing determines what app or view is launched.

SAP Fiori Launchpad Configuration Guide:

“Target mappings define navigation logic using semantic object/action. Tiles use these to determine routing targets.”

Semantic object alone is not actionable.

SAP Fiori elements support rendering of:

Micro Chartsusing @UI.chart inside table columns.

Imageswith appropriate annotations or formatter logic.

Text, the default for most line item entries.Charts and nested tables are not rendered inside cells.

SAP Fiori Elements Developer Extensibility Guide:“Micro charts can be embedded in cells… Images and formatted text are supported.”

Deployment Targetsfor SAPUI5 apps from BAS include:

SAP BTP(via HTML5 App Repository or MTA).

SAPUI5 ABAP Repositoryon an on-premise or S/4HANA backend system.

SAP Deployment Guide:

“Deployment to ABAP repository or HTML5 App Repository on SAP BTP is supported. SAPUI5 Java repo is deprecated.”

Fiori Launchpad is not a deployment target but a UI layer.

SAPUI5 supports three maindata binding modes:

One-way: Data flows from model to view.

Two-way: Data syncs both directions (used in forms).

One-time: Data is injected once and not updated.

SAPUI5 Developer Guide:

“Binding modes define how data is synchronized between the model and the view. The supported modes are: OneWay, TwoWay, OneTime.”

Three-way and resource-model binding are invalid or unrelated to binding modes.

manifest.json:

Describes the application structure, routing, models, and resources.

Acts as the central metadata descriptor.

SAPUI5 SDK:

“The manifest.json is the application descriptor containing metadata for deployment, models, routing, and UI configuration.”

Component.js bootstraps the app, but manifest.json holds app metadata.

TheAnalytical List Page (ALP)is ideal for applications requiring:

Charts

Visual filters

Thesap.m.FacetFiltercontrol fires:

confirm: when filters are applied.

reset: when the user clears filters.

SAPUI5 API Reference - FacetFilter:“Events include 'confirm', 'reset', triggered by user interactions.”

listFilter/oninit are not defined FacetFilter events.
