Understanding V-Model Phases

In the V-Model, which testing phase corresponds directly to the System Design phase in development?

A System Testing

B Unit Testing

C Integration Testing

D Acceptance Testing

💡 Hint

Think about which test verifies the complete system against system design.

System Testing verifies the entire system against the system design specifications, matching the System Design phase in the V-Model.

Verification vs Validation in V-Model

Which statement best describes the difference between verification and validation in the V-Model?

A Verification is done after coding; Validation is done before coding.

B Verification ensures the product is built correctly; Validation ensures the product meets user needs.

C Verification checks if the product meets user needs; Validation checks if the product is built correctly.

D Verification and Validation are the same and done simultaneously.

💡 Hint

Verification is about correctness of building; Validation is about meeting requirements.

Verification ensures the product is built according to specifications (correctly), while Validation ensures the product meets the user's actual needs.

Test Case Trace in V-Model

Given the following test case trace, what is the final validation phase executed?

Requirements Specification -> Design -> Coding -> Unit Test -> Integration Test -> ???

A Regression Test

B System Test

C Acceptance Test

D Smoke Test

💡 Hint

Think about which test validates the product against user requirements at the end.

Acceptance Testing is the final validation phase where the product is tested against user requirements before delivery.

Assertion on V-Model Testing Levels

Which assertion is TRUE about the relationship between development and testing phases in the V-Model?

A Each development phase has a corresponding testing phase directly linked to it.

B Testing phases occur only after all development phases are complete.

C Testing phases are performed before any development phase starts.

D Testing phases are independent and do not relate to development phases.

💡 Hint

Recall the shape of the V-Model and how phases align.

The V-Model pairs each development phase with a corresponding testing phase, showing direct relationships.

Identifying Incorrect V-Model Mapping

Which option incorrectly pairs a development phase with its testing phase in the V-Model?

A Requirements Analysis - Acceptance Testing

B Coding - Unit Testing

C High-Level Design - System Testing

D System Design - Integration Testing

💡 Hint

Integration Testing corresponds to which design phase?

Integration Testing corresponds to Low-Level Design, not System Design. System Testing pairs with System Design.
