What is Service Virtualization?

Service Virtualization is a method that helps you to emulate (virtual services) the behaviors of the component in a Service Oriented Architecture (Microservice). Practically the software development, testing, and operations teams do not work in synch, and each team has to wait for others to have components ready. This causes delays in workflows and may deliver an inferior product. With Service Virtualization, DevOps teams use virtual services instead of production services, so they can test the system even when key components are not ready. With Service Virtualization, integrating of applications takes place early in the development cycle thereby reducing time and cost to fix errors.

Here, is the list of top Service Virtualization tools with popular features and download links-

1) Traffic Parrot

Traffic Parrot makes it easy for developers and testers to do service virtualization, mocking, and simulation. It helps create tests faster and with less effort by providing simulators and mocks of backend APIs and third-party systems. Both junior and senior developers and testers find it easy to get started by following the tutorials available online.

Management and architects favor Traffic Parrot because it allows for time to market reduction and delivering DevOps and Agile transformations due to flexible licensing model, support for many protocols and compatibility with Continuous Integration tools.

Features:

  • Support for HTTP(S), JMS, IBM MQ and File transfers
  • For developers and testers (both manual and automated testing)
  • Compatible with Docker, Kubernetes, and OpenShift. It is ideal for testing microservices.

2) ServiceV Pro

ServiceV Pro gives development and testing teams the ability to create, configure, and deploy virtual APIs with ease- increasing system availability and reducing QA costs and bottlenecks. Users can easily create virtual APIs via recording live traffic, building out a RESTful service in our UI, or simply importing a Swagger or WSDL spec, then share the service with other team members.

Features:

  • Virtualize REST and SOAP services and data with no technical skills needed
  • Reuse and share virtualized APIs on your local machine or in a public or private cloud
  • Customize response behavior such as latency, response times, and network congestion
  • Import a just a Swagger spec to start testing an API before it's built

3) Wiremock

WireMock is simulator tool for HTTP based API. It allows you stay test even when an API does not exist or is incomplete. It allows checking of an edge case and failure modes that the real API may not able to produce.

Features:

  • Robust and power API URL request matching.
  • Record and Playback tool
  • Hosted Mock API service. No need to configure servers and set SSL certificates.

4) Mountebank

Mountebank is an open source tool which can execute multi-protocol tests. The codebase is Node JS. It is easy to create stubs and mocks.

Features:

  • Mountebank tool aims to be fully cross-platform, with native language bindings
  • It is non-modal and multi-protocol solution. It can test SMTP, HTTP, TCP, and HTTPS
  • This tool provides service virtualization service free of cost without any platform constraints
  • Frequently updated, mature, and stable tool.

9) Mocklab

Mocklab is service virtualization tool with user-friendly UI. It allows easy copy, paste or record stubbed HTTP responses. It helps for easy sharing among the team.

Features:

  • Helps organization to remain productive even when a dependent API doesn't exist
  • Test edge case and failure modes which the real API never able to produce
  • Helps to recognize issues faster and find key issues with the feature of help of visual request log

Why Service Virtualization?

Here, are prime reasons for using service Virtualization for your business:

  • Helps you to accelerate Application Delivery while mitigating business risks
  • It helps you to simulates the behavior of select components within an application to enable end-to-end testing of the application as a whole.
  • Allows the teams to work in parallel
  • Allows you to Test Early and often which expose defect when they are faster, easiest and least costly to resolve
  • Facilitates better test coverage
  • Virtual services offer rich tools for editing and managing which help you improve productivity, cut down on maintenance time and development costs.
  • It is useful for anyone involved in developing and delivering software applications.
  • Access to more systems and services
  • It supports test-driven development.
  • Gives you an isolated environment for testing
