Given this test snippet for Splitwise financial logic:

initial_balance = 100
expense = 40
new_balance = initial_balance - expense
assert new_balance == 60

Step-by-Step Solution

Solution:

Step 1: Understand assertion behavior
An assertion checks if a condition is true; if false, it raises an error.
Step 2: Connect assertion failure to test result
If the assertion fails, the test framework reports an error indicating failure.
Final Answer:
An error is raised indicating a failed test -> Option B
Quick Check:
Assertion fail = Error raised [OK]

Quick Trick: Remember assert stops test on failure [OK]
