RAP400 - Writing ABAP Unit Tests for Apps built with the ABAP RESTful Application Programming Model (RAP)
Build and test modern Apps with the ABAP RESTful Application Programming Model (RAP)
This repository contains the exercise materials for a RAP workshop on testability called RAP400 - Writing ABAP Unit Tests for Apps built with the ABAP RESTful Application Programming Model (RAP) - which is all about quality assurance in the development of modern Apps with RAP.
In this session we will guide you through the development of a transactional UI service and the creation of different types of ABAP Unit tests for a RAP business object (BO) developed with the ABAP RESTful Application Programming Model (RAP) and and the OData service exposing the BO for a transactional SAP Fiori elements-based application.
The RAP service to be tested with ABAP unit tests will be exposed for a UI use case with the OData V2 protocol, and the resulting app will look like this:
You will write different ABAP Unit tests in the following exercises to ensure the quality of an OData service developed with the ABAP RESTful Application Programming Model. The OData service is based on the ABAP Flight Reference Scenario. It is the underlying UI service of a SAP Fiori elements based Travel managing app - i.e. creating, updating and deleting travel records.
Please Note
The focus of this session is not on any development methodology such as Agile/Scrum or test-driven development (TDD), but rather on the technical implementation of unit tests, i.e. how to write ABAP unit tests for a given RAP based applications.
Ensuring the high quality of applications has a very high priority in the whole software development lifecycle. As an application developer, you want to be able to write, for example, unit, scenario and integration tests to verify the application behavior as a whole. The ABAP platform offers different mechanisms and frameworks to achieve this. The main options here are ABAP Unit Tests und the ABAP Test Cockpit.
Writing ABAP Unit tests is the way to provide high quality software, which can be easily evolved over time without introducing regressions. In methodologies, like extreme programming and test driven development, the role of unit testing is even more important.
ABAP unit is the state-of-the-art unit testing framework for ABAP. It's embedded into the ABAP programming language which supports you in writing unit tests. In ADT you have various possibilities to execute the unit tests and to evaluate the results concerning functional correctness and code coverage.

The requirements to follow the exercises in this repository are:
- You have installed the latest ABAP Development Tools (ADT), see ABAP Development Tools
- You have created a SAP Business Technology Platform (BTP) ABAP Environment Trial account and connected your ADT to the Trial Account using a ABAP Cloud Project, see Create an SAP BTP ABAP Environment Trial User
Follow these steps to build a RAP-based simple App with a helper class and write various ABAP unit tests for it.
