V & V PROCESS MODEL :

V&V Model is Verification & Validation Model.In This Model We work simultaneously Development and Testing.In this Model One V for Verification and one For Validation first 'V' we follow SDLC(software Development Life Cycle) and Second 'V' we follow STLC-(Software Testing Life Cycle).

• Testing normally done in a large system in 2 parts. The functional verification and validation against the Requirement specification and Performance evaluation against the indicated requirements.
• Testing activity is involved right from the beginning of the project.
• Use of V&V process model increases the rate of success in a project development company to deliver the application on time and increases the cost effectiveness.

Testing Related Activities During Requirement Phase

• Creation and finalization of testing template.
• Creation of test plan and test strategy .
• Capturing Acceptance criteria and preparation of acceptance test plan.
• Capturing Performance Criteria of the software requirements.

Testing activities in Design Phase

• Develop test cases to ensure that product is on par with Requirement Specification document.
• Verify Test Cases & Test Scripts by peer reviews.
• Preparation of traceability matrix from system requirements.

Testing activities in Unit Testing Phase

• Unit test is done for validating the product with respect to client requirements.
• Testing can be in multiple rounds.
• Defects found during system test should be logged in to defect tracking system for the purpose of resolving and tracking.
• Test logs and defects are captured and maintained.
• Review of all test documents.

Testing activities in Integration Testing Phase

• This testing is done in parallel with integration of various applications or components.
• Testing the product with its external and internal interfaces without using drivers and stubs.
• Incremental approach while integrating the interfaces.

Performance testing

• This is done to validate the performance criteria of the product/ application. This is non-functional testing.

Business Cycle testing

• This refers to end to end testing of real life like business scenarios.

Testing activities during Release phase

• Acceptance testing is conducted at the customer location.
• Resolves all defects reported by the customer during Acceptance testing.
• Conduct Root Cause Analysis (RCA) for those defects reported by customer during acceptance testing.
