V Model

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.
