What will be the output of this test code snippet if the function under test returns 5 instead of 10?
def test_value():
    result = get_value()
    assert result == 10
ASyntax error in test code
BTest passes successfully
CTest fails with an assertion error
DTest is skipped automatically
Step-by-Step Solution
Solution:
  1. Step 1: Understand the assertion

    The test expects result to be 10.
  2. Step 2: Analyze actual result

    If get_value() returns 5, assertion 'result == 10' fails.
  3. Final Answer:

    Test fails with an assertion error -> Option C
  4. Quick Check:

    Assertion mismatch = Test failure [OK]
Quick Trick: Assertion must match actual result to pass test [OK]
Common Mistakes:
MISTAKES
  • Assuming test passes despite wrong result
  • Confusing syntax errors with assertion failures
