1. Unit IV – Chapter 2
V-Test Model

3. V- Model
Structured Approach to Testing: Test policy and Test Strategies.
Activities during each phase of Software Development Life Cycle: 5 Ws(What, Where, When, Why and Who and How)
Analyse Structures Produced during development phase for adequacy and testability: Coverage's, Artifacts, Documents

4. Generate Test Sets based on Structures: Functional Testing, Structural Test, Requirements/Designs, Validation Testing
Additional Activities during Design and Coding: High level design and Low level design ensure complete coverage of requirements.
Determine that structures are consistent with previously generated structures: Consistency between various phases.
Refine and Redefine test sets generated earlier: changes in requirements, designs and artifacts.

5. Testing during Proposal Stage
A proposal is created when the customer asks for information, quotation and proposal. Feasibility study, Economic feasibility, implementation feasibility, organizational fit, process fit and people fit.

6. Testing during Requirement stage
Adequate
Clear
Verifiable/ Testable
Measurable
Feasible
Not conflicting with each other

7. Testing during Test Planning Phase
Generate test plan to support development activities: development methodology, schedule and deliverables, test strategy, test objectives, assumptions, risks.
Generate Test cases: functional and non-functional requirements, test cases and test data.
Analyse requirements/Design Coverage: requirement coverage, design coverage.

8. Testing during Testing phase
Consistency with respect to requirements
Analyse design for errors
Analyse error handling
Developers verify information flow and logical structure
Testers inspect design in detail

9. Aspects to be checked Missing test cases Faulty Logic
Module Interface mismatch
Data Structure inconsistency
Erroneous Input / Output
User interfaces inadequacies
Correctness of decisions and conditions along all paths
Inconsistency with respect to requirements and high level design

10. Testing during coding phase
Aspects to be checked:
Coding standards/Guidelines Implementations
Coding Optimization
Coding Interpreting Design
Unit Testing

11. VV Model Requirements Requirements Verification
Requirements Validations
Design
Design Verification
Design validation
Coding
Coding Verification

12. Critical roles and responsibilities
Development:
Project Planning, resourcing, Interacting with customer, Defining policies, supporting testing team, doing development related activities.
Testing: Test planning, resourcing, Interacting with customer, defining policies, supporting development team, doing acceptance testing.
Customer: specifying requirements, participating in acceptance testing, review and approve
