10 Best Service Virtualization Tools in 2021

Service Virtualization Tools

In this post, we see the best Service Virtualization Tools. Some of the popular Service Virtualization Tools are as follows:

What is Service Virtualization?

Service Virtualization emulates the behaviors of components such as devices, APIs, networks, databases, etc., that are unavailable or difficult to access while testing and allows in-depth functional testing and performance testing in parallel. 

Check our guide to learn more about Service Virtualization.

Why Service Virtualization Testing?

  • It can be used by everyone who is involved in the application life cycle.
  • It allows you to test earlier in the application development process by emulating the unavailable component dependencies. So you can achieve integration testing without any delay.
  • It allows teams to work in parallel
  • Reduces cost and saves a lot of time
  • Easier to do a proof of concept (POC)
  • Better test coverage
  • It gives better test coverage

Popular Service Virtualization Software

Now in this section, we will see the above tools in detail.

1) Parasoft Virtualize

Parasoft Virtualize

Parasoft Virtualize is a service virtualization software that can create, deploy, & manage virtual test environments anytime anywhere to help both development and QA teams. It allows the executing of complex test scenarios by capturing the required system behavior of dependent applications and virtual assets. It lets us create virtual assets that we can build and manipulate to behave just like the real ones.


  • It comes with a powerful visual interface that allows you to manage and create virtual services
  • Even non-technical team members can use it easily 
  • Integrates with third-party DevOps tools such as Jenkins, Bamboo, Jira, TeamCity, or Azure DevOps.
  • It supports continuous testing through on-premise or in the cloud services such as Amazon EC2, Microsoft Azure.

IBM Rational Test Virtualization Server



IBM Rational Test Virtualization Server software enables early and more parallel, continuous testing of complex applications in the development lifecycle. It virtualizes part or all of an application or database that allows software testing teams to move forward without waiting for the availability of those resources to start testing.


  • It enables you to update, reuse, and share virtualized services
  • Supports a broad set of middleware and messaging technologies from Software AG, TIBCO, and other integration providers in healthcare, finance, and B2B.
  • It supports integration with other tools like IBM Rational Quality Manager, Collaborative lifecycle management
  • Flexible pricing and deployment

4) Broadcom Service Virtualization (formerly CA Service Virtualization)

Broadcom Service Virtualization

Broadcom Service Virtualization product (formerly CA Service Virtualization) simulates unavailable systems across the software development lifecycle (SDLC), allowing developers, testers, integration, and performance teams to work in parallel for faster delivery and higher application quality and reliability. You’ll be able to accelerate software release cycle times, increase quality, and reduce software testing environment infrastructure costs.


  • It enables parallel software development and testing that accelerates time to market. 
  • Test earlier in the software development life cycle where issues are less expensive and easier to fix.
  • Reduce the costs of third-party services or pay per use services.

7) WireMock


WireMock is a simulator tool for HTTP based APIs. It enables us to stay test even when an API we depend on does not exist or is not complete. It supports the validation of edge cases and failure modes that the real API won’t reliably produce. It acts fast and reduces the build time from hours to minutes.


  • Its flexible deployment allows you to run WireMock from within our JUnit test, Java application, Servlet container, or as a standalone process.
  • It supports XML and JSON
  • Provides record and playback and allows us to run quickly by capturing traffic from and to an existing API.
