The document discusses the importance of quality in service-oriented architectures (SOAs). It notes that SOAs involve reusable components, business flexibility, and higher levels of integration across diverse technologies. This necessitates testing at the component level early in development. Traditional software testing is too late and UI-focused, whereas SOA testing requires approaches like message-oriented testing of loosely coupled services. Challenges in SOA testing include complex standards, defect isolation across integrated systems, and testing in heterogeneous environments. The document recommends tools like SOAPUI and JMeter for functional and performance testing of SOA components and web services.

4. Glance at SOA
A Service Oriented Architecture is a set of components which can be
invoked and whose interface descriptions can be published and
discovered.

17. SOA Testing

18. SOA Testing
• Component based testing
• Bottom-up test execution
• Early involvement in testing
• Collaborative testing
• Interop testing
• System testing (End-to-End)

19. SOA Testing
• Test Automation

Unit

Integration

End-to-End
• Continuous Integration
• Performance Testing

20. SOA Testing – Planning and Design
• Study business requirements
• Identify components
• Identify service consumers
• Identify message exchanging patterns (MEPs)
• Identify testing techniques
• Set scope

21. SOA Testing Challenges
• Complex standards and specifications
• Message oriented tests
• Headless applications
• Defect isolation
• Complex test environments due to higher level of integrations
• Heterogeneous platforms
• Cloud complexities

22. SOA Testing in Practice

23. SOA Testing in Practice

24. Component Level Testing – Web Services
• Understand WSDL
• Mock Services based testing
• Service level performance testing

25. Web Services Testing with Quality Of Services
(QoS)
• Service access is restricted using various policies (security,
throttling)
• WS-Security
• WS-RM

26. Testing associated with Broker (ESB)
• Message routing
• Transformations
• Split/aggregate messages

27. Open Source Tools for SOA Testing – SOAPUI
• Easy-to-use
• Can be used for both functional and performance testing
• WS-* Support
• Service mocking

28. Open Source Tools for SOA Testing – Jmeter
• SOAP/XML-RPC or WebService Samplers can be used
• Can be used for both functional and performance testing
• Data-driven testing
