Testing Fundamentals - Why Software Testing Matters

A test report shows a bug fixed during testing costs $400. The report mistakenly states fixing it during coding costs $600. What is the error and the correct coding cost if testing costs 4 times coding cost?

AError: coding cost too low; Correct coding cost is $1600

BError: coding cost too high; Correct coding cost is $100

CNo error; coding cost is correct

DError: testing cost too low; Correct testing cost is $2400

Step-by-Step Solution

Solution:

Step 1: Understand cost relation
Testing cost = 4 * coding cost; Given testing cost = $400.
Step 2: Calculate correct coding cost
Coding cost = 400 / 4 = $100; Report states $600, which is too high.
Final Answer:
Error: coding cost too high; Correct coding cost is $100 -> Option B
Quick Check:
Coding cost = Testing cost / 4 = $100 [OK]

Quick Trick: Divide testing cost by 4 for coding cost [OK]

Common Mistakes:

Assuming coding cost is higher than testing
Not dividing testing cost correctly
Ignoring the cost relation
