Model-Based Integration Testing for SAP® ERP Based on BPMN Standard

Share Article

TransWare Software Solutions AG, the innovative provider of SAP® application lifecycle software solutions announces the availability of the Model-based Integration Testing for SAP® for SAP Solution Manager and HP Quality Center.

For the requirements definition of SAP ERP software, the management discipline and methodology of Business Process Management (BPM) has an important role in the Blueprint project phase of an ERP implementation. Using the BPM methodology, the business requirements are documented and analyzed. Process improvement is achieved via better support of business activities by the ERP software. The Blueprint consists of functional, organizational and system process models developed by a Business Process Analysis (BPA) tool prior to the realization phase of customizing the ERP software. Because of the complexity of ERP software, the integration testing of ERP supported processes is a very essential task to lower business impacts of badly tested software. At the same time, testing is a resource-consuming task in critical project phases.

TransWare offers an adaptive software solution for automatically transforming Blueprint business process models from various modeling standards into test cases based on BPMN modeling standard for a methodical and tool-based integration testing using SAP Solution Manager or HP Quality Center (QC). The solution addresses the reduction of costs and risks and improved quality of the implemented ERP software.

At least 50% efforts are reduced by automatically generated test cases. By re-using business know-how from business process models defining probabilities of process flows, the test cases can be prioritized only re-testing an appropriate number of test cases when software changes and not the full set of test cases for a business process that is very time consuming in execution of the test cases.
Integration of test case tools like HP QC or SAP Solution Manager test-management speeds up the handling of test cases in complex ERP projects, as compared to manual analysis and description of test cases especially when the test cases change through change requests.
By examining end-to-end business scenarios with high probabilities, the automation of tests with tools like HP Loadrunner or SAP eCATT scripts save big amounts of time by re-running theses test during change requests or ERP maintenance. The overall efforts are greatly reduced for costly resources of the QA team and business key-users.

Many business executives have concerns about the quality and resulting costs for implementation and maintenance of ERP software. By using the model based approach for integration testing, the business impact of insufficiently tested ERP software is eliminated. By the re-use of business logic given by process models and execution probabilities combined with systematic execution of prioritized end-to-end scenarios, the relevant states of a business processes are reviewed. This includes identification and explicit testing of interfaces for exchange of data between activities supported by different involved ERP and 3rd party software components.
A more methodical and tool-supported approach by using tools lowers the risk of influence of inexperienced QA team members and insufficient project time available for testing.
For revisions of business software, automatically generated test documentation can be used to audit and review test cases.

Using business process models as a basis of their generation, the test cases re-use documented process knowledge. The use of BI technology to analyze test case data and the visual documentation of test case diagrams improves the analytical understanding of end-to-end business scenarios. Based on test cases it is much easier to define appropriate test data for integration and for functional use case testing.
The integrated approach addresses the impact given by business requirement changes to test cases in the ERP project cycle or during the maintenance of ERP. The changed test cases can be re-tested again to eliminate side effects of software changes.
