Testing Fundamentals - Why Software Testing Matters

A project fixes bugs at different stages with costs: $80 at requirements, $240 at design, $480 at coding, $960 at testing, and $1920 at maintenance. If the team fixes 4 bugs during design and 3 during testing, what is the total extra cost incurred by fixing bugs during testing instead of design?

A$960

B$2160

C$720

D$1440

Step-by-Step Solution

Solution:

Step 1: Calculate cost difference per bug
Testing cost - Design cost = 960 - 240 = $720 extra per bug.
Step 2: Calculate total extra cost for 3 bugs
3 bugs * $720 = $2160 extra cost.
Step 3: Check if 4 design bugs affect calculation
Only testing bugs cause extra cost compared to design.
Final Answer:
$2160 -> Option B
Quick Check:
Extra cost = 3 * (960 - 240) = $2160 [OK]

Quick Trick: Multiply testing bugs by cost difference [OK]

Common Mistakes:

Including design bugs in extra cost
Using wrong cost difference
Multiplying by wrong bug count
