- 1. Speed the development of robust integrations with IBM Integration Bus and Rational Integration Tester Carsten Börnert – Integration Specialist Emanuel Stanciu – Cloud DevOps Specialist
- 2. Agenda 1. Introduction 2. Testing capabilities in IBM Integration Bus (IIB) v10 3. Rational Integration Tester – Overview 4. Implementing stubs for use with IIB 5. Test suites and Continuous integration 6. Demo 2
- 3. Introduction
- 4. Scope of testing • Applications, Services, Libraries using a variety of transports, formats and subflows • Unit testing – how big/small is a unit? • Message transformation • Message routing • Subflows • System testing – what exactly constitutes the system? • The system is the Message Flow • System integration testing • End-to-end interactions 4
- 5. Testing capabilities in IBM Integration Bus v10
- 6. IIB v10 Flow Exerciser • Introducing the flow exerciser • Save messages • Trace path through flow • Inject messages • Supported nodes • MQInput, HTTPInput, SOAPInput • Use for testing of • Subflows • Message transformations • Message model testing • Error handling • Using API to automate • Java or REST 6 Check out the blog on developer.ibm.com/integration https://developer.ibm.com/integration/blog/2015/06/03/using-flow-exerciser-iib-v10/
- 8. Presentation layer Integrations, data and business logic Only one-tenth of an iceberg is above water Traditional UI testing Automated Integration Testing and Service Virtualization The majority of risk in modern systems is seldom tested as it is unseen.
- 9. Today, integration of enterprise applications still follow the “big-bang” approach … • Integration amongst different components of the enterprise application occur at the end of a milestone in a “big-bang” • Difficult to continuously integrate and deploy across different technology stacks and varying delivery schedules. Very hard for different teams to collaborate together on interim builds inside a milestone Mobile component Web component Mainframe component 1 week Big Bang ! 1 week Big Bang !
- 10. Tests can bypass the UI and execute beneath the iceberg. Test while your system is being built and at an accelerated rate. Much greater coverage = much greater confidence Introduces the concept of testing side effects. Validate the contents of message queues, log files and databases as well as simple inputs/outputs. Shift Left with Automated Integration Testing
- 11. The Continuous Testing Solution: RTW, RPTS, RTVS • IBM Rational Test Workbench – Enable functional, performance and integration testing throughout your project lifecycle – With a scriptless, wizard-driven test authoring environment and support for more than 70 technologies and protocols • IBM Rational Performance Test Server – Save time and effort by reusing your functional integration tests for performance testing – Combine your tests to model real-world scenarios and assess the impact of load on your integrated infrastructure. • IBM Rational Test Virtualization Server – Model real system behavior to eliminate test dependencies and simulate production, – Accelerate testing and reduce the setup and infrastructure costs of traditional testing environments. Test Servers Load Agents Virtualization Agents QA DEV
- 12. The bottom line Using IBM’s test automation and virtualization can eliminate long back-end test cycles, increase quality, and lower risk. Test early and continuously with virtualization •Verify and validate the technical solution for a business change without waiting for the complete technical solution to be built. Test integrations •Most of the risk of business change lies at the integration layer and WebSphere solutions need to be tested below the UI. •Verify side effects such as database writes or log file updates for greater confidence. Test performance •Verify scalability after upgrading or migrating to the WebSphere platform. •Be confident before you add Minimize Risk with RTW and RTVS

IBM Rational Test Virtualization Server supports multiple platforms and protocols Transport/Protocol Message Formats Technologies • ActiveMQ • Email (SMTP, IMAP) • Files • FTP/S • HTTP/S • WebSphere MQ • Java RMI • JMS • SAP IDoc, BAPI, RFC • Software AG’s IB & IS • Sonic MQ • TCP/IP • TIBCO Rendezvous, Smart Sockets & EMS • CICS TG • CICS IPIC • IMS Connect • MQTT • .Net Objects • Bytes • COBOL Copybook • ebXML • ASC X12 • UN/EDIFACT • DFDL • Fixed Width • Java Objects • MIME • SOAP • Software AG Broker Docs • SWIFT • CHIPS • FedWire • TIBCO ActiveEnterprise • HL7 v3 • XML (DTD, XSD, WSDL) • ISO8583 • Custom • CentraSite • Oracle Fusion • SCA Domain • Software AG IS, Broker, BPMS • WebSphere Application Server • WebSphere Message Broker • WebSphere MQ • Websphere SI Bus • Sonic ESB • System z (CICS and IMS) • TIBCO ActiveMatrix • UDDI • Web Services • WebSphere RR • WSDL • BPM • Databases • Log Files Supporting technologies the business depends on Protocols, message formats, and technologies

- 17. SWIFT/MQ HL7/TCP X12/SOAP JSON/RES T IBM Integration Bus SAP PI CICS Database App Server Integration Testing and Service Virtualization can significantly de- risk the migration and reduce the time required. Development/test teams can build against virtual services and test early and test continuously using messages captured from the real systems. Exception/edge case testing is much easier to do. RTW understands a wide range of technologies and messaging protocols (including DFDL) making it well-aligned to IIB users Most Orchestration Engines have their own proprietary runtime (unlike JEE) which means migration between vendors involves risk as development is required. Test environments are expensive and it is extremely difficult to fault-find in an environment with many moving parts Example Scenario: IBM Integration Bus – Migration from other vendors
