Service Virtualization

Service Virtualization Delivers Stable Virtual Services
— When and Where You Need Them

Easy-to-Use Service Virtualization

The services your application calls might not be available for testing when you need them. Service virtualization creates stable virtual services that mirror the real thing. Integrate it into automated testing solutions for the continuous testing that DevOps pipelines demand.

Expand Test Coverage With Service Virtualization

Gain Access Any Time

Access the dependent services your application needs to talk to for accurate and thorough testing even if they are unavailable or incomplete at the time of testing.

Isolate Service Dependencies

When you can’t access the relevant service, its associated interdependencies are also a black box. Service virtualization studies and replicates such interdependencies in the virtual equivalent, delivering accurate testing.

Ensure Test Stability

Incomplete or unstable services can lead to failures and delays in testing. A virtual equivalent is more stable, delivering reliable automation and peace of mind while testing.

Leverage Script-Free Tooling

Testers don’t need to write complicated scripts. Script-free tooling allows even novice testers to participate. In the occasional case where scripting is a must, Parasoft supports a variety of programming languages.

Accurately Mirror Real-World Behavior

Parasoft’s service virtualization studies the application's actual calls to live services to accurately model the virtual version.

Conduct Negative and Edge Case Testing Effectively

It’s difficult to make a dependent service intentionally behave in a bad way but these extremes need to be considered for accurate testing. Parasoft ensures that the virtual service meets a variety of testing conditions for more thorough testing.

Parasoft Service Virtualization

Easily scale from a single user to a full DevOps deployment across teams. Parasoft’s service virtualization empowers testers and developers to weave automated testing early into development cycles while delivering virtual and stable services as and when needed.

Where Is Service Virtualization Used?

Any software organization with modern service-oriented architectures can use service virtualization as part of its automated testing processes. Compressed software development cycles and dependencies on services mean that developers and testers need to whip up virtual services that can simulate the real thing.


The finance industry depends heavily on a wide range of message formats and protocols, such as ISO 8583, FIX (Financial Information eXchange), Swift, and EDI (electronic data interchange). The problem: each call to such a service must contend with a proprietary messaging format. Creating a virtual test service to simulate that messaging and nesting it within a contextually relevant test environment makes testing easier to automate. The result is reliable and secure software that keeps pace with today's high-stakes Agile software development.


While the industry has embraced microservices to create applications as part of Agile software development, it must also continue to address the scalability needed to handle a larger number of diverse devices and endpoints. When access to the systems is unstable, service virtualization fills in the gaps.

Hospitality & Travel

Chatbots. Mobile service. Online bookings. Customer loyalty programs. Agile software development in the industry mandates testing across a variety of platforms while staying ahead of intense competition. Service virtualization helps accelerate quality software development that meets customers’ exacting demands.


Almost all government interactions such as requests for proposals, bid packages, purchase orders, contract negotiations, and more involve electronic data exchange. The Agile software development that forms the backbone of such transactions must also contend with clunky legacy systems. Service virtualization eliminates the guesswork needed to decode the “black box” in such complicated interdependencies.

Retail & e-Commerce

The industry works with a roster of third-party services both on the customer-facing side and at the backend, including credit card payment systems such as ISO 8583. Service virtualization becomes increasingly vital to simulate these real-life equivalents.

Healthcare & Insurance

The industry integrates with a variety of third-party services, calling any of which can create bottlenecks. To ensure proper operation while protecting patient information, negative testing can address corner cases and extreme situations that could occur. Software development needs robust and reliable service virtualization on demand that can ensure alignment with HL7 and EDI standards.
