www.opitz-consulting.com Automated tests are the key for quality assurance and for ensuring business agility from a long-term perspective. That is especially important in complex integration projects, independently if you develop your integrations on-premise or in the cloud. If a hybrid strategy is used it is important to have a consistent testing approach for cloud and on-premise. In this session we will show how to implement a consistent DevOps approach to establish short release cycles and to deliver system integration projects successfully. We will show how-to test aspects like BPEL, BPMN, Service Bus, Java, Human Tasks, XSLT and XQuery across all relevant test layers (Elementary Unit Tests, Component Tests, End-to-End Tests) by following the same approach.
