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

Agile development: Where we wanted to be!
 Target approach was agile
 Small, incremental deliverables
 In-time business value generation

Lessons Learned
„Never start a (cloud) integration project
without an appropriate DevOps
approach.“
But how to establish it efficiently?

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

 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 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

 Common approach in Java/JEE development
 Ensures that intended behavior is tested properly
 Consistent testing approach
 Flexibility
 Extensibility
Anti-Pattern
