ABAP Unit Testing

Guide for writing effective ABAP Unit tests including test class setup, assertions, test doubles, mocking frameworks, and test environments for CDS, SQL, and RAP.

Workflow

1. Determine the testing goal:

   • Testing business logic in a class method
   • Testing a CDS view entity
   • Testing a RAP BO behavior implementation
   • Testing database-dependent logic with SQL test doubles
   • Setting up test doubles for external dependencies

2. Choose the right approach:

   • Direct unit test for pure logic (no dependencies)
   • Constructor/setter injection for mockable dependencies
   • CDS test environment for CDS view tests
   • OSQL test environment for SQL-dependent code
   • RAP BO test doubles for RAP behavior tests
