Improving Application Testing Through Service Virtualization

It’s a parallel universe! While quantum physics may still be over-the-top for most of us, the need for parallel processes when it comes to software/application development and testing is a widely acknowledged fact. Service Virtualisation is a set of tools that are used to deliver high-quality glitch-free applications while optimizing resources and time. This in turn helps gain optimum ROI. Service virtualization helps in improving the efficiency and functionality of applications, cutting down on the lifespan of the software development cycle. It also allows companies to increase the frequency of app releases/updates.   

Visualize – Virtualize

Back in 1913, when Henry Ford introduced the first moving assembly line, it was an innovation that revolutionized production by allowing for the parts to be put together in record time. Despite this, the assembly line would only work if the components were ready. Software and application development is, oftentimes, still stuck in the Dark Ages where teams suffer from delays due to internal or external dependencies. Testing delays, waiting for components to be fully developed, and for third-party deliverables to come through can cause a bottleneck that your business can ill afford. This is where Service Virtualisation steps in to save the day.

Service virtualizations simulate the functionalities, data, and performance of the components of an application that are still not fully developed or are inaccessible. This means that the integration of the APIs, databases, networks, etc. need not hold up end-to-end testing of the application itself. If you can visualize the end product, you can virtualize the components and run extensive performance and functionality testing modules through service virtualization.

Need for Speed

Developing complex applications with features such as continuous integration and continuous delivery (CI / CD) could involve challenges for the testing team. Environmental components that are unavailable at the testing stage, dependent on third-party deliveries, constantly evolving, or even out of the scope of testing can cause a loss of time and productivity. Service virtualization bridges this gap by allowing integration as and when the components are made available but by keeping the end-to-end testing systems going. Not only does this allow the testers to replicate the environment but it also helps in the component development process by flagging issues early on, improving overall quality. The Gartner survey of over 500 companies using service virtualization reveals that most of them saw a considerable boost in test rates and nearly a third managed to cut down on their test cycle spans by 50%.

The Service Virtualization Advantage

Optimized development and testing cycles – Running development and testing parallelly removes bottlenecks and encourages multiple teams to work simultaneously.

Eliminates environmental constraints – By simulating third-party services and evolving components, service virtualization eliminates many of the constraints faced by the testing teams. It also helps eliminate the parallel demand for environments by endpoint testing processes.

Reduction in costs – The application of virtual testing affects a savings potential of about 50-60% on the project cost. Parallel deployment of teams and elimination of errors and redundancies at an early stage of app development makes for lower costs.

Quality is King

Elimination of errors and improvement in quality is possibly the best outcomes of implementing Service Virtualization. Diagnosing and eliminating errors at an early stage improves quality drastically. About 50 percent of the Gartner Survey respondents saw an error reduction by 40% due to the implementation of Service Virtualisation.

At STL, we understand the value addition made by Service Virtualisation to the application ideation to release cycle. We bring to the table pivotal insights and learnings from across the globe. With COVID-19, the service virtualization market is set to expand at an unprecedented rate and we at STL are at the forefront of application testing services.
