Quality - The Key toSuccessful SOAbyCharitha KankanamgeSenior Technical Lead, Manager QAWSO2

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

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.

Glance at SOA Building blocks of SOA

Glance at SOA Common Principles of SOA● Services are reusable

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

Importance of Quality in SOA

Importance of Quality in SOA

Importance of Quality in SOA➢ Reusable components

Importance of Quality in SOA➢ Business flexibility

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

Traditional Software Testing

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

SOA Testing

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

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

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

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

SOA Testing in Practice

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

Component Level Testing – WebServices - Demo

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

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

Testing associated with ESB - Demo

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

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
