Case Study #1 – Project Approach (Target)
n Target approach was agile
n Small, incremental deliverables
n In-time business value generation

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 maturity
n Analysis of the status quo: Where we are and where we want to be?

„ “Never start a (cloud) integration project
without 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 CS
n 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 CS
n 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 - Git
n Build Automation
n Ant, Maven, Gradle, npm, Grunt,
Bower, Gulp, Command line
n Continuous Integration - Hudson
n Issue Tracking
n Code review
n Deployment automation
n Agile process management
n Wiki
n Activity Stream

3 Testing in (cloud)
integration projects
Source: http://softwareengineeringdaily.com/tag/continuous-delivery/

Challenges in (cloud) integration projects
n 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 XQuery
n XSLT
n NXSD
n Java
n Java callouts
n Custom XPath functions
n JAX-WS / JAX-RS Web Services
n Services / Processes
n Service Bus Services
n SOA Composites

4 OC Testframework

Oracle SOA OOTB testing capabilities
n Design-time tests for transformations (XQuery, XSLT)
n Design-time tests for Business rules
n Test suites for SOA composites
n Mocking of services/inbound messsages (Process initiation) at composite level
n Mocking of references/outbound messages (Emulations) at composite level
n Definition of XML assertions (Strict and similar)
n Define tests for BPEL components on BPEL activity level
n Variable and fault assertions
n Bypass blocking activities like waits
n Assert activity executions
n No testing capability for Mediator, Human Task, BPMN

OC SOA Testing Framework
n 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

Features
n 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 pipeline
configurations/properties)
n Check execution of BPMN audit trail (activty execution, etc.)

Comparison OOTB Testing vs. OC SOA Testing
OOTB OC SOA Testing
Test-driven approach - ✔
Test automation Composites only ✔
Mocking ✔ ✔
Support for test types
• Unit
XSLT / XQuery design-time only
Composites ✔
Service Bus –
✔
• Isolation Composites only ✔
• Integration Manual ✔

Benefits
n Test-Driven Development (TDD)
n Common approach in Java/JEE development
n Ensures that intended behavior is tested properly
n Consistent testing approach
n Flexibility
n Extensibility
Anti-Pattern
