Testing is the process of verifying the functioning of S/4HANA with an intent to find out whether the ERP system meets the specified requirements. Testing is essentially a quality assurance process that ensures the correct operation of SAP S/4HANA before the project implementation Go-Live. Also, testing is not just restricted to the project implementation and project go-live phase. SAP S/4HANA is a new-generation ERP with regular updates and new releases. So, testing is necessary at each upgrade and therefore, customers must realize that SAP S/4HANA Testing is a continuous never-ending process.
