   • Validation ensures the right product is being developed.

3. What is the V-Model in software testing? The V-Model is a software development model that emphasizes testing at each stage of development.

Test Design Techniques

1. What is Equivalence Partitioning? Equivalence Partitioning is a test case design technique where input data is divided into partitions of equivalent data.

2. Explain Boundary Value Analysis (BVA). BVA is a test design technique where test cases are designed on boundaries of input values.

3. Test Case Development

4. 1. What components should a test case document contain?

      • Test Case ID
      • Test Case Description
      • Test Steps
      • Expected Results
      • Actual Results
      • Pass/Fail Criteria

   2. What is Traceability Matrix? A Traceability Matrix is a document that maps requirements against test cases.
