Case Study #1 – Project Approach (Target)n Target approach was agile

n Small, incremental deliverables

n In-time business value generation

Source: http://www.commonplaces.com/blog/agile-vs-waterfall-how-to-approach-your-web-development-project/


Case Study #1 – Project Approach (Reality) n Static and cumbersome

n Insufficient test automation and no budget for DevOps

n Releases became too complex

Test maturityn Analysis of the status quo: Where we are and where we want to be?

Minimum Target Reality

No tests


Continuous integration / delivery

„ “Never start a (cloud) integration projectwithout an appropriate DevOps approach.

But how to establish it efficiently?


2 Oracle SOA CS and Oracle Developer CS


Oracle Cloud Services

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


Oracle SOA CSn Full suite of developer tools

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

n Oracle manages the infrastructure

n Fully automated provisioning

n Provides complete access, so that administrators can tune, configure, and monitor the SOA environment as with on-prem


Oracle Developer CSn Complete development platform provided as a service to enable

an agile development process and to automate DevOps & delivery

n Dev CS supports: Continuous Integration, Continuous Delivery and Collaboration

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


Developer CS – What‘s inside? n Version Management - Gitn Build Automation

n Ant, Maven, Gradle, npm, Grunt, Bower, Gulp, Command line

n Continuous Integration - Hudsonn Issue Trackingn Code reviewn Deployment automationn Agile process managementn Wikin Activity Stream


3 Testing in (cloud) integration projects

Source: http://softwareengineeringdaily.com/tag/continuous-delivery/


Challenges in (cloud) integration projectsn Complexity

n Distribution of systems / services

n Wide range of different technologies & skills

n Multiple data sources

n Test automation

n Deployment automation

n Consistent monitoring (E2E)


Testing assets in SOA CS n Transformations

n XQueryn XSLTn NXSD

n Javan Java calloutsn Custom XPath functionsn JAX-WS / JAX-RS Web Services

n Services / Processesn Service Bus Servicesn SOA Composites

4 OC Testframework


Oracle SOA OOTB testing capabilitiesn Design-time tests for transformations (XQuery, XSLT)

n Design-time tests for Business rules

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

n Variable and fault assertionsn Bypass blocking activities like waitsn Assert activity executions

n No testing capability for Mediator, Human Task, BPMN


OC SOA Testing Frameworkn Java-based framework

n Developed and enhanced in several projects

n Uses provided Oracle APIs

n Supports SB Service testing

n Supports integration testing for SB and SOA composites

n Consistent integration in CI environment

n Earns further maturity through usage in international projects

n Supports SOA Suite 11g and 12c


Featuresn Execute XQuery, Xsl and Nxsd tests

n Validate XML requests and responses

n Call services

n Intercept service calls

n Mock services (WS, JCA adapters, Human tasks)

n Manipulate runtime artifacts (DVMs, SB pipelineconfigurations/properties)

n Check execution of BPMN audit trail (activty execution, etc.)


Comparison OOTB Testing vs. OC SOA TestingOOTB OC SOA Testing

Test-driven approach - ✔

Test automation Composites only ✔

Mocking ✔ ✔

Support for test types

• UnitXSLT / XQuery design-time only

Composites ✔Service Bus –

Benefitsn Test-Driven Development (TDD)

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

5 Demo


Setup 1/2n Create new project in DevCS (Initial repository)

n Adjust local Maven settings to use DevCS Maven repository

n Populate Maven repositoryn 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

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

n Add additional libraries needed by the OC SOA Testingframework


Setup 2/2n Commit & push your code to DevCS Git repository

n Deploy your artifacts to SOA CS

n Define the Hudson build jobs that executes testsn Pre-deploy test (XQuery, Xsl, Nxsd)n Post-deploy test (SOA composite tests, SB services)

n Find a detailed description with the basic steps:https://community.oracle.com/community/cloud_computing/platform-as-a-service-paas/oracle-developer-cloud-service/blog/2015/11/05/soa-cloud-service-developer-cloud-service-integration
