2. Abstract
Idle time of the team always increases because of inter/intra dependencies, which in turn impact project cost and delivery dates. To address such challenges, Virtualization helps testing team to achieve their goals effectively.
This paper outlines the involvement of virtualization at right time in Agile project(s) to improve productivity, reduce cost and deploy high quality software in brief time.
API Virtualization
Service Virtualization
A virtual oriented environment will allow an organization to mix and match a combination of business logic software, the data and the servers on which the application runs. Virtualization emulates the performance of components in a virtual set-up instead of pooling resources for production. With the help of virtualization, end to end testing is possible without the dependent components. In this era of technology products are developed with multiple components/features and API(s). In the absence of features and API, following concept will help to start testing earlier:

3. What is Virtualization?
Virtualization emulates the performance of components in a virtual set-up to help address the challenges of Service and API oriented Architecture (SOA) testing strategy. At the same time, if implemented effectively, Virtualization can speed up the testing process
Virtualization is the equivalent of allowing you (or, in this case, your testing team) to taste a cake – its flavor, texture, and all – before it has finished baking
API virtualization is the process of using a tool that creates a virtual copy of your API, which mirrors all of the specifications of your production API, and using this virtual copy in place of your production API for testing.
For the development of most enterprise applications, which rely on a mixed array of system components working together in harmony, service virtualization “fills in the gaps” of missing system components by simulating their responses to show how the various components interact.

4. Product Problem Statement
Due to inter-dependencies of API(s) and Components, testing will not be performed until all modules are completely developed and integrated
Product
Internal API
External API
Component1
Component2
Component3
Cost and delivery dates will never meet
QA will wait for the completion of development and impacting the project in following ways:
Testing of the product will be delayed almost by 1 sprint.
Testing is delayed, defect will also be reported lately, fixing of the defect will also take time
In case of blocker issues, work of entire team would be impacted and overall project will be delayed

5. Possible Approaches Classic Increase Team Size Involve Virtualization
Delivery dates will be pushed because of delayed in starting regression testing
Increase Team Size
Increasing team size is beneficial to achieve the delivery dates but cost of the project will increase
Involve Virtualization
Through virtualization, independency to QA team will be provided from the starting of the project to complete the testing on time. Neither project cost, Nor delivery dates will be hampered
