PyTest - Writing Assertions

What is wrong with this pytest assertion?

def test_total():
    total = 4 + 4
    assert total == 8 == True

AThe assert statement is missing a message

BThe variable 'total' is not defined

CThe assertion uses a chained comparison incorrectly

DThere is no error; the assertion is correct

Step-by-Step Solution

Solution:

Step 1: Analyze the assertion
The expression total == 8 == True is a chained comparison.
Step 2: Understand chained comparisons
It checks if total == 8 and 8 == True. Since 8 == True is false, the whole assertion fails unexpectedly.
Step 3: Correct usage
The assertion should be assert total == 8 without chaining.
Final Answer:
The assertion uses a chained comparison incorrectly -> Option C
Quick Check:
Chained comparisons can cause logic errors [OK]

Quick Trick: Avoid chaining comparisons in assert statements [OK]
