This document discusses the importance of quality in service-oriented architectures (SOAs) and SOA testing. Some key points: - Quality is especially important in SOAs due to reusable components, business flexibility, and higher integration levels. - SOA testing focuses on component-level and bottom-up approaches rather than traditional top-down and UI-focused testing. It involves techniques like message testing and collaborative testing. - Challenges in SOA testing include complex standards, headless applications, defect isolation in integrated environments, and heterogeneous platforms. - Open-source tools like SOAPUI and JMeter can be used for functional and performance testing of SOA components and services.

2. Agenda
● SOA – Quick look
● Importance of quality in SOA
● Traditional software testing
● SOA testing
● Challenges in SOA testing
● SOA testing in practice
● Open source SOA testing tools
● Summary

3. 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.

4. Glance at SOA
Building blocks of SOA

5. Glance at SOA
Common Principles of SOA
● Services are reusable

6. Glance at SOA
Common Principles of SOA
● Services are loosely-coupled

10. Importance of Quality in SOA

11. Importance of Quality in SOA
➢ Reusable components

12. Importance of Quality in SOA
➢ Business flexibility

13. Importance of Quality in SOA
➢ Higher level of integrations and diverse technologies

14. Traditional Software Testing

15. Traditional Software Testing
• Test execution starts when an end-to-end solution
is ready
• Higher UI interaction
• UI oriented test automation
• Too much focus on black-box testing

16. SOA Testing

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

18. SOA Testing
• Test automation
➢ Unit
➢ Integration
➢ End-to-End
• Continuous integration
• Performance testing

19. SOA Testing – Planning and Design
• Study business requirements
• Identify components
• Identify service consumers
• Identify Message Exchange Patterns (MEPs)
• Identify testing techniques
• Set scope

20. 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

Services
• Understand WSDL
• Mock services based testing

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

32. Testing associated with Broker
(ESB)
• Message routing
• Transformations
• Split/Aggregate messages

35. Open Source Tools for SOA Testing –
SOAPUI
• Ease-of-use
• Can be used for both functional and performance
testing
• WS-* support
• Service simulation

36. 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
