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

- 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
- 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
