Service Virtualization Overview

Parasoft Service Virtualization helps development and QA teams access the complete, realistic test environments needed to develop or test an application—anytime, anywhere. Testing is often delayed or cut short because it's difficult to access the complete, realistic test environments required to test meaningful transactions. By replacing unavailable dependencies with easily accessible and configurable "virtual assets", service virtualization allows teams to start testing earlier, test more completely, and test continuously.
  • Capture and simulate live system behavior from recording
  • Rapidly model incomplete/unavailable components from service definitions and logs
  • Easily configure complex test conditions (e.g., “what-if,” security, concurrency, fail-over, performance, and negative test scenarios)
  • Simulate any system interactions—supports REST & web services, plus an industry-leading 120+ protocols/message types
  • Get the exact test environment you need, on-demand

Test Environment Management

Parasoft Continuous Testing Platform (CTP) integrates and extends the above API testing and service virtualization capabilities via an intuitive web-based interface for creating, managing, sharing, and executing test environments (including service virtual assets) and tests. Environment Manager (a component of CTP) unites test environment management (test environment setup, visualization, validation, and provisioning), service virtualization (virtual asset creation, configuration, and deployment), and API testing (test creation, management, and execution).
  • Visualize the dependencies associated with an AUT and specific test environments
  • Easily configure all test environment components—including virtual asset performance, test data, and response logic
  • Instantly provision "disposable" test environments with zero impact to the organization
  • Identify test environment issues before they compromise the accuracy of your test results
  • Assess the impact of a change to any specific component

SV for Agile Development

  • Rapidly prototype virtual assets that reflect the anticipated behavior of still-evolving components
  • Easily update virtual asset behavior as requirements change
  • Rapidly deploy virtual assets for consistent team-wide access
  • Eliminate the need for brittle stubs/mocks

SV for Functional Testing

  • Test against constrained dependent resources without scheduling hassles
  • Test extensively—without access and transaction fees
  • Test vs. a broad array of conditions instantly
  • Get the exact test environment you need, on demand

SV for Performance Testing

  • Test versus realistic transaction performance
  • Test constrained dependent resources without scheduling restrictions
  • Test extensively—without access and transaction fees
  • Test against a broad array of functional and performance conditions—with minimal setup
  • Get the exact test environment you need, on demand


SV for Mobile App Testing

  • Gain anytime, anywhere access to a complete test environment
  • Easily configure performance tests against realistic network conditions
  • Emulate network conditions from production or via profile libraries
  • Reduce dependencies on other teams and divisions
  • Eliminate late-stage integration issues

SV for Mainframes

  • Create simulated test environments for mainframes
  • Give dev/QA immediate and flexible access to simulated mainframe behavior
  • Reduce the cost & complexity of development/testing
  • Accelerate delivery via early and continuous testing
  • Minimize disruption to high-value mainframe resources

SV for SAP

  • Provide flexible, immediate, and secure access to Client-SAP, Internal SAP, and SAP-to-SAP interactions
  • Enable early, extensive integration testing from the dev/test environment
  • Facilitate deep regression testing to ensure migrations/upgrades meet expectations
  • Gain deep visibility and traceability within and across processes
  • Increase the scope and breadth of testing without increasing test lab costs
