Eliminate Testing Delays From Unstable Dependencies & Environment Provisioning Bottlenecks

When the systems you depend on aren’t available, your testing slows down—or stops completely.

With Parasoft Virtualize, you don’t have to wait for APIs, services, or environments to be ready. Start building and testing integrations earlier, even before dependent services are available. You can simulate what you need and keep your work moving on your timeline.

Build Virtual Services Without Writing Code

You don’t need scripting skills or deep domain expertise to create and maintain virtual services.

Easily configure virtual services and attach data sources to simulate realistic, data-driven behavior.

With Virtualize you can:

Generate and maintain REST API mocks through agentic AI workflows.
Build virtual services from example requests and responses.
Scriptlessly create virtual services from OpenAPI, Swagger, WSDL, or other definitions.
Create always up-to-date simulations through continuous traffic recording of live systems.
Autonomously switch from live services to virtual services when dependencies go offline or become unstable.
Reuse and share services across your team.

Simulate the Enterprise Systems Your Application Depends On

Your applications depend on diverse system interactions—REST APIs, event streams, messaging systems, databases, and legacy services. With Virtualize, simulate them all on one platform, ensuring your tests exercise application behavior against realistic simulations of every system and protocol it depends on.

REST and SOAP APIs
Kafka event streams and messaging systems
IBM MQ and JMS queues
gRPC-based microservices
GraphQL endpoints
EDI transactions and legacy systems
MCP services and tools for AI-driven workflows
120+ protocols and message formats

Create Virtual Services That Behave Like Real Systems

Go beyond simple mocks. With Virtualize, create virtual services that reflect real-world behavior. Define responses based on inputs and conditions. Simulate delays, failures, and edge cases. Drive behavior with external data.

Virtual services can also maintain state across interactions, allowing data to be created, reused, updated, and deleted (CRUD) within a test session. That means simulated systems behave like real applications, not static responses.

Scale Virtualization Across Teams & Pipelines

Reuse and share virtual services across your organization to eliminate duplication and delays. Standardize environments across teams, reduce dependency bottlenecks, and run tests in parallel without any obstacles. With centralized test environment management, teams can automatically switch between live and virtual services when dependencies become unstable, keeping test automation uninterrupted.

Spend less time coordinating. More time building.
