SOA Quality Management is the process to assure services meet business requirements by validating service functionality and operations throughout the SOA Lifecycle

What is SOA Quality Management?

SOA Lifecycle

SOA Quality Management is continuous and takes place within each phase of the SOA Lifecycle

the soa testing strategy
The SOA Testing Strategy
  • The only way to effectively test SOA projects is to….
    • start from the ground up.
    • test the inputs and outputs of individual modules.
    • assemble sections of logic together and test smaller sections of the integration flow.
    • Assemble those smaller sections into a finished SOA project and perform an end-to-end test on the fully assembled project.
  • Key tenants
    • Focus on the business processes in requirements and testing
    • Create test plans that account for assembly of services
    • Create an automated and repeatable testing process
    • Plan for typical SOA testing hurdles (e.g. security access, unavailable systems)

Test early, test often is more important now than ever (due to the domino affect a bug in a service may have on a given business process and the possibility of that service being in many business processes)

soa adoption increases modularity change bringing quality to the forefront
SOA adoption increases modularity & changeBringing quality to the forefront

Business impact

  • Service and application SLAs will be impacted by more frequent updates
  • Cross-organization Business/IT organizations will have increased complexity

Pain of modularity

  • Lower level of functionality & performance both at individual service level & composite application
  • Increased risk and need to manage distributed assets
  • Increased management of a larger number of services including custom, outsourced & packaged

Decentralization, modularity and increased risk drives need for a structured approach of integrated requirements, architecture & lifecycle quality management

Quality Management of Service Oriented Architecture Applications

The IBM Rational Solution is a three pronged approach

challenge the cost time quality tradeoff governance of the software delivery process

“There’s too much to test. Where do we begin ?”

“I have requirements, I have tests and I have defects…but nothing ties them together”

“Everyone uses different tools – there’s no way to share data between the team.”

Challenge: The Cost - Time - Quality TradeoffGovernance of the software delivery process

Your job is to deliver quality applications.On Time. On Budget. You need to coordinate teams, data, schedules, requirements, models, code, tests, results and reports. Are you ready?

slide13

“How can we leverage our Business Process analysis in our services testing efforts?”

“We don’t want to pull Programmers off their projects to write complex test harnesses.”

Challenge: Validating SOA component functionality & performanceEnsuring functionality of composite application units

Web Services are the building blocks of SOA applications. A single service is a stand-alone component but may be used in dozens of systems. Some of those services will be yours, some not.How do you test a service without the rest of the system? Does it work? All the time? Under load? Are you sure?

“The Web Service is ready for testing, but there is no user interface to exercise it.”

slide14

“How can I communicate problems found

in the field back to development?”

Challenge: Post Deployment Monitoring of ServicesCreating a feedback loop from operations to development

Congratulations you’ve gone live. How are things going out there? Do you know? What happens when you need to make a change? And what if operations found a problem – how would it get back to development? Do these groups communicate?

“How can I monitor web services running on many different platforms against thousands of users?”

“How do I change policies and ensure those changes don’t break the implementations?”

service in the context of soa
Service (in the context of SOA)
  • A self contained business function in which consumers interact through a well defined interface (contract).
  • The consumer does not know (or care) "how" the service implements the requested business action - only that the service performs "what" is defined by its published interface (contract).

A service in the context of an SOA

An abstracted view of SOA concepts

wsdl web service description language
WSDL – Web Service Description Language
  • An XML-based service description on how to communicate using web services.
  • Defines services as collections of network endpoints, or ports.
  • Specification provides an XML format.
  • The abstract definition of ports and messages is separated from their concrete use or instance, allowing the reuse of these definitions.
  • WSDL is often used in combination with SOAP and XML Schema to provide web services over the Internet.

functional regression testing strategy
Functional & Regression Testing Strategy
  • Quickly test Web Services and setup desired regression Test Cases.
  • Ease-of-use in setting up these tests will help promote testers to test their Web Services early and often.
  • Easy Test Case Management and Setup is vital to a productive establishment and maintenance of functional & regression tests.
  • Setup an environment where the impact of requirement and business process changes can be quickly analyzed and realized

performance testing strategy
Performance Testing Strategy
  • QA Testers & Network Engineers should test the scalability and robustness of web services and determine performance and endurance characteristics of their WSDL operations.
  • Performance Tests should determine:
    • response times
    • latency
    • throughput profiles
    • endurance
    • robustness
    • scalability
