Testing Fundamentals - Non-Functional Testing

What will be the output of this code simulating a performance test?

max_users = 10
current_users = 0
while current_users < max_users:
    current_users += 2
print(f"Users reached: {current_users}")

AUsers reached: 10

BUsers reached: 12

CUsers reached: 8

DUsers reached: 0

Step-by-Step Solution

Solution:

Step 1: Trace the loop increments
current_users starts at 0; while current_users < 10: increment by 2 -> 2, 4, 6, 8, 10. After increment to 10, condition check 10 < 10 is false, loop exits. But since increment happens inside loop, last increment makes current_users 12.
Step 2: Understand loop exit condition
Loop runs while current_users < max_users; increments by 2 each time. When current_users is 8, next increment makes it 10 (still < 10?), then next increment makes it 12, which breaks the loop.
Final Answer:
Users reached: 12 -> Option B
Quick Check:
Loop increments can overshoot condition [OK]

Quick Trick: While loop increments can overshoot exit condition [OK]
