Software Engineering - SDLC Models

Why does the V-model emphasize early test planning alongside development phases?

ATo avoid writing test cases until coding is done.

BTo detect defects early and reduce costly fixes later.

CTo delay testing until the entire system is built.

DTo focus only on unit testing and ignore integration.

Step-by-Step Solution

Solution:

Step 1: Understand early test planning purpose
Planning tests early helps find defects sooner, saving time and cost.
Step 2: Contrast with late testing
Delaying testing increases risk and cost due to late defect discovery.
Final Answer:
To detect defects early and reduce costly fixes later. -> Option B
Quick Check:
Early test planning reduces defects and costs [OK]

Quick Trick: Early test planning saves time and money [OK]
