Waterfall development: Where we didn’t want to be! Static and cumbersome Insufficient test automation and no budget for DevOps Releases became too complex

be? Minimum Target Reality

Lessons Learned

„Never start a (cloud) integration project without an appropriate DevOps approach.“

But how to establish it efficiently?


Oracle SOA CS and ODCS 2





Oracle Cloud Services

Source: https://cloud.oracle.com/developer/services




Oracle SOA Cloud Service (SOA CS) Full suite of developer tools

including OSB (Virtualization), BPEL (Orchestration), B2B, Managed File Transfer, Adapters for Connectivity, API Management

Oracle manages the infrastructure

Fully automated provisioning Provides complete access, so

that administrators can tune, configure, and monitor the SOA environment as with on-prem

Demo – SOA CS



Seite 18

Oracle Developer CS (ODCS) Complete development platform provided as a service to enable

an agile development process and to automate DevOps & delivery

Dev CS supports: Continuous Integration, Continuous Delivery and Collaboration

Is included as a free entitlement with trial and paid orders of Java Cloud Service, Java Cloud Service-SaaS Extension, Messaging Cloud Service, Mobile Cloud Service, SOA Cloud Service and Application Container Cloud

Developer CS – What‘s inside? Version Management - Git Build Automation Continuous Integration - Hudson Issue Tracking Code review Deployment automation Agile process management Wiki Activity Stream

Challenges in integration projects Complexity Distribution of systems / services Wide range of different technologies & skills Multiple data sources Test automation Deployment automation Consistent monitoring (E2E)




Testing assets in integration projects Transformations

XQuery XSLT NXSD

Java Java callouts Custom XPath functions JAX-WS / JAX-RS Web Services

Services / Processes Service Bus Services SOA Composites

Test layers in detail Elementary Unit Tests

What – Tests the atomic functionality of the implemented code Goal – Provide quality feedback for the developer in short and fast cycles Where – NAV and MW developer using mocks on Development environment

Component Tests What – Tests the integrative functionality of the implemented code Goal – Provide possibility to skip blocker and continue with next component Where – QA using SOAP UI tests on Test environment

End-to-End Test What – Tests the complete functionality of a process Goal – Assure that the process is running as defined by the requirements Where – QA using real applications for tests on Integration environment

OC Testframework 4




Oracle SOA OOTB testing capabilities Design-time tests for transformations (XQuery, XSLT) Design-time tests for Business rules Test suites for SOA composites

Mocking of services/inbound messsages (Process initiation) at composite level Mocking of references/outbound messages (Emulations) at composite level Definition of XML assertions (Strict and similar) Define tests for BPEL components on BPEL activity level

Variable and fault assertions Bypass blocking activities like waits Assert activity executions

No testing capability for Mediator, Human Task, BPMN




OC SOA Testing Framework Java-based framework Developed and enhanced in several projects Uses provided Oracle APIs Supports SB Service testing Supports integration testing for SB and SOA composites Consistent integration in CI environment Earns further maturity through usage in international projects Supports SOA Suite 11g, 12c and SOA CS




Features Offline testing for XQuery, XSL and NXSD Validate XML requests and responses

Definition of Xpath assertions Definition of XML Equals assertions

Call SOA composite and SB services Manage SOA composite and SB services Intercept service calls Mock services (WS, all kind of JCA adapters, Human tasks) Manipulate runtime artifacts (DVMs, SB pipeline

configurations/properties) Specific functionality for BPMN process testing




Comparison Oracle OOTB Testing and OC SOA Testing

OOTB OC SOA TestingTest-driven approach - ✔Test automation Composites only ✔Mocking ✔ ✔Support for test types

• UnitXSLT / XQuery design-time only

Composites ✔Service Bus –

✔

• Isolation Composites only ✔• Integration Manual ✔




Benefits Test-Driven Development (TDD)

Common approach in Java/JEE development Ensures that intended behavior is tested properly

Consistent testing approach Flexibility Extensibility

Anti-Pattern

Setup OC SOA Testing framework Create new project in DevCS (Initial repository) Adjust local Maven settings to use DevCS Maven repository Populate Maven repository

mvn deploy:deploy-file -DpomFile=oracle-maven-sync-12.1.3.pom -Dfile=oracle-maven-sync-12.1.3.jar -Durl=https://developer.us2.oraclecloud.com/profile/ developer88301-deoracleem99369/s/developer88301-deoracleem99369_soa-cloud-testing_10988/maven/ -DrepositoryId=odcs

mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=$MW_HOME -Doracle-maven-sync.serverId=odcs -P odcs

Add additional libraries needed by the OC SOA Testingframework
