Kronos discusses how service virtualization can aid your organizations' continuous testing efforts. Original presentation was made at our first annual user conference, SmartBear Connect.

1. Continuous Testing with Service

The world of dependencies

• We were required to give our public APIs to our internal customers for integration in a
month.
• Our sales team already partnered with some external customers and they also
needed the APIs for integration in 45 days.
• We needed to integrate with more than 20 third party APIs with lot of limitations:
o No Test environment. Paid APIs
o Environment down for maintenance
o Available during a time-period of the day
What we needed

This was the story of every other composite application

• Test waiting for dev teamto build services
• Unstable/unavailable/time-limited Services
• Low Test Coverage due to unavailability of Services
• Third-Party Services
➢ Pay-pertransaction
➢ Transactional limits
QATeams were hit the most

• Different from Server Virtualization or Virtual Machines
• Not really mocking and stubbing
• Emulates the behavior of software components to remove dependency constraints
• Not just virtualizing web services, service virtualization extends across all aspects of
composite applications: services, databases, mainframes, ESBs, JMS etc.
ServiceVirtualization:What it is and what it is not

12. Page
• Recording livecommunication among components as the system is exercised from the
application under test (AUT)
• Analyzing service interfacespecifications (such as a Swagger or WSDL)
• Defining the behavior manually
• Virtualassets aredeployed locallyor in the cloud.
Different ways toVirtualize

Virtual Asset as a Proxy
• Virtualasset canwork as a proxy
betweenthe consumer and the
realservice.
• If needed VirtualServicecandirect
allrequests to realservice or
selectiveservicesonly.
• When realservice is built, you can
choose toredirectallthe calls.

14. Page
• Lesser constraints on QAand development teams
• Shorter Development Cycles due to ParallelDevelopment and testing
• Reduced cost
• Improved Product Quality
• Enable performancetesting when 3rd partyservices don’t provide performance environment
• Allow test teamstoeasily manage their test dataand increase their test coverage.
• Actas a prototype for quick feedbackfrom customers and finalize the requirement
