Accelerating Service Virtualization Adoption With Agentic AI

Learn how Parasoft's latest release of Virtualize transforms service virtualization by introducing an industry-first AI assistant that enables teams to create accurate virtual services using natural language.

Creating virtual services that accurately simulate real system behavior has long been one of the biggest roadblocks to adopting service virtualization.

While the benefits are clear—faster feedback, fewer environment constraints, and better test coverage—realizing that value has traditionally required advanced skills, deep domain knowledge, and significant time investment. As a result, many QA teams struggle to build and maintain virtual environments on their own, leaving service virtualization strategies stalled and ROI unrealized.

Modern applications only raise the stakes. With complex APIs, evolving microservices, and AI-infused systems becoming the norm, simulating real-world behavior is more critical—and more difficult—than ever.

What if you could build those simulations just by simply describing your needs in natural language?

Parasoft’s latest release of Virtualize delivers a first-of-its-kind breakthrough: an embedded agentic AI Assistant that empowers teams to generate complete virtual services simply by describing what they need in natural language.

This is more than an incremental improvement—it’s a game-changer. Whether you’re simulating third-party APIs, mimicking unavailable or incomplete dependencies, or supporting API-first development, Parasoft Virtualize now makes virtual service creation dramatically faster and more accessible—no specialized skills or coding required.

From Conversation to Configuration: How Agentic AI Works in Virtualize

Parasoft is the first to bring agentic AI to service virtualization—introducing a powerful new way to generate virtual services using natural language.

At the core of this innovation is the AI Assistant embedded in the Virtualize UI, a chat-based interface that lets users simply describe the operation names and payload structures of the service they are simulating. The assistant interprets the request and takes care of the setup—automating what previously required extensive technical expertise.

You might request:

"Create a virtual service for a payment processing API. There should be a POST and a GET operation. The operations should require an account id along with other data related to payment."

The assistant uses a large language model (LLM) to interpret the instruction and draws on optionally provided API service definitions, sample requests/responses, or written descriptions of the service. It then automatically generates a fully configured virtual service, complete with dynamic behavior, parameterized responses, and appropriate default values.

This means less time spent on configuration and more time validating real-world scenarios—so teams can move faster without sacrificing realism or reliability.

Making Service Virtualization Accessible to More Teams

Service virtualization has historically been viewed as a task for technical experts. But with the AI Assistant, Parasoft Virtualize opens the door to non-technical testers, business analysts, and newer team members.

Now, anyone who understands how a service should behave can contribute to virtual service creation using simple, natural language instructions.

This lowers the barrier to entry and enables:

• Broader adoption of service virtualization across teams
• Faster onboarding of new testers
• More collaborative test environment creation across QA, development, and DevOps

This also aligns perfectly with API-first and shift-left testing practices, giving teams the ability to simulate services early in the SDLC, before backend components are implemented or stable.

Why It Matters

When you combine natural language interaction, agentic reasoning, and AI-powered automation, you unlock a new level of speed, precision, and accessibility in software testing. Parasoft is proud to be the first test automation platform to offer agentic AI generation capabilities for both API test scenarios and virtual services—removing the complexity that has traditionally limited adoption.

With Parasoft’s AI Assistant, teams can now:

In Virtualize:

• Create complete virtual services from API service definitions, sample request-response pairs, or a simple written definition —no scripting required
• Generate test data and auto-parameterize virtual assets by describing data requirements to the AI Assistant in natural language
• Accelerate API-first and shift-left practices by simulating services earlier in the SDLC, even before service definition files are created

This leap forward isn’t just about smarter technology—it’s about unlocking tangible benefits that teams can realize immediately.
