The document discusses integrating test-driven development (TDD) practices into SAP Solution Manager change management processes. It proposes additional roles for verification by a solution architect and peer review. Steps are added to the change document for testing and peer review before approval. Integrating transport-related checks from the ABAP Test Cockpit provides added value. While developers may not have less work or more flexibility, they can focus on business tests and gain easier maintenance through increased transparency and a single source of truth.

Added-Value for the developer is only provided by the documentation of the results. The transparency
provided for the other stakeholders involved in the change managmeent process should also be considered.

SolMan meets TDD: Transport-Related Checks
37
Additional Checks provide an added Value. They can be used outside of solution manager if the ST-PI plug-in is
installed.
Available Checks
Cross-system object lock (CSOL) check
Cross reference check
Downgrade protection (DGP) check
Critical object check
ABAP test cockpit (ATC) check
Code inspector check
Customer-specific check (BAdI implementation)
Can be called directly on the system under TX: /SDF/TRCHECK

Developers…
 think about design before implementation
 don‘t have less work
 don‘t gain flexibility
 do have less documentation
 have easier maintenance
 can concentrate on
the business tests
Tester…
 has more transparency/information
 has a single source of truth
Change Manager…
Customers…
 save costs
 get better code quality
