Timothy JosephService virtualization provides a simulated interface to QA teams, and helps them complete their tests on the application under test (AUT). It is primarily used for testing APIs, Cloud Architectures, and Service Oriented Architecture based applications.
Dev and QA teams can now work together on simulated environments to write test scripts and develop services in parallel which can lead to faster releases.

Architecture
Traditional Automation Testing Vs Service Virtualization
-
Traditional Automation Testing
- Automation dependency on development phase to be completed
- Non-availability of environment as used by many teams in parallel
- Difficult to configure and test unavailable and inaccessible resources
- Delay in mocks, POC demos, and reporting to client
- Environment are often down due to deployment and configuration issue
- Test data setup and lead times problems
-
Automation With Service Virtualization
- Automation goes in parallel with development phase
- Virtual environments are available for QA and Dev teams to work in parallel
- Easy to test unavailable and inaccessible resources
- Simulated environment enables on-time mocks, POC demos, and delivery to client
- Less environment deployment and configuration issues
- Less test data setup and lead time problems
- Increase in test coverage virtual assets
- Enhance the scope of automation testing
- ‘Shift Left’ strategy benefits all the teams

Conclusion
Service virtualization is an emerging concept that overcomes the limitations of dependent systems and enables the QA engineers to develop end-to-end tests in parallel to the development phase. SQA companies should include this concept in their development lifecycle to speed-up the automation as well as release processes.
