How often you push your “Phone Updates” to a later date as an update install means your phone would not be available to work. Even though the updates just take a couple of minutes, but in a fast-paced world where a minute delay could mean a lot, non-availability of services for a fraction of seconds frustrate you.
Often the similar situation is faced by a Tester/QA while performing his daily testing jobs – environments are not up, dependencies are ambiguous, developers/business users need the SIT environment and ‘n’ number of such reasons.
That’s where Service Virtualization comes into the picture!
In fact, Service Virtualization is all about continuity and boosting agility!
Service Virtualization in laymen terms is providing services in a virtual manner. Just like on the internet you have virtual friends, virtual classroom or virtual 3D view of an art gallery, in a similar fashion the services exist for a tester/QA to test, but are not the real services.
Service Virtualization by its means simplifies the issues faced by a Service-Oriented Architecture [SOA] testing strategy. By providing a virtual set-up of services, it speeds up the testing and development process.
A quick example that I could think of is “market data” provided by Bloomberg, Reuters, ACTIVE, WOMBAT that is the lifeline of many investment firms. But for a tester to test the market data scenarios they are connected either with a simulator or a different service that stores the recorded data [ a replica of live data].
By connecting to a virtual service, testing is continuous, and the live environment does not get affected.
Technology is making things simpler for the end users, but complexity is hidden beneath under wraps giving a tough time to developers and testers. Be it chatbots, Pokemon Go or a virtual reality venture showcasing you hotel suites from your living room, the building/testing of tools and apps is not simple enough. To streamline the testing/developing process service virtualization when combined with #Agile becomes handy -
As in our last post, we saw “ The Best Practices of Continuous Agile Testing” we know continuity is the key for any software/tool to survive. With service virtualization, we are a step closer to make it continuous agile and quality-assured!
