Service Virtualization Guide | Introduction, Benefits, Tools

Service Virtualization

To execute test cases successfully, all of the dependent components such as devices, databases, APIs, networks, etc., must be available with proper functionality, test data, and configuration. This is difficult in real-time due to Software Development (Dev) and Operations (Ops) teams won’t work in synchrony and each team has to wait for other teams for availability of components. It creates delays in workflow. Some of the reasons for unavailability of components are difficulty in setup, still under development, undergoing maintenance, too costly to use, blocked by other teams, owned by the third party, etc.,

To overcome this most of the top companies are investing in Service Virtualization. So what is Service Virtualization?

What is Virtualization?

Virtualization is the creation of a virtual (rather than actual) version of a device or service, such as a hardware platform, OS, storage device, or network resources.

What is Service Virtualization?

Service Virtualization emulates the behaviors of components (such as devices, databases, APIs, networks, etc.,) that are unavailable or difficult to access while testing and allows in-depth performance and functional testing in parallel. It plays an important role in successful Shift Left Testing. Testers can continuously conduct integration testing at any point in the Software Development Life Cycle with the help of Service Virtualization thereby allows us to save costs through identifying issues earlier in the life cycle, reduces time to market, removes dependencies, increase the business value and allows a team to deliver high-quality features.

As per the Gartner survey, companies using service virtualization were achieving greater software quality, in less time, with less cost.

Benefits of Service Virtualization

Benefits of Service Virtualization are as follows.

Reduce Dependencies: Removes dependencies by mimicking the behaviors of components and allows the teams to work in parallel

Reduce Time to Market: Reduces time to market by speeding up release cycles and delivers high-quality services

Reduce Costs: To save costs through identifying issues earlier in the life cycle

Increase Business Value: Eliminates bottlenecks caused by application complexity and increase the business value

Increase Quality: Improved overall quality of the product with fewer defects reaching production
