Quick Questions

Shade in the A or B circle for each question.

1. Your program printed 'Total: 45' but you wrote the actual result as '45'. Is this the right way to record it?

A Yes. Shortening the output is fine as long as the number is the same

B No. Copy the actual result exactly: Total: 45

2. Expected result: 12. Actual result: 12. What verdict do you record?

A Fail

B Pass

3. Expected result: 7.5. Actual result: 7. What verdict do you record?

A Fail

B Pass

4. A test fails because the program output 20 but you expected 25. What should you do with the expected result?

A Leave it as 25 and record the Fail

B Change it to 20 so the test passes

5. Which entry in the Notes column is better for a failed test?

A Output was 20 but 25 expected. Total may be missing the last item

B Failed

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1Expected: 15 \| Actual: 15 \| Result: Pass		AThe result is marked Pass even though the actual result (10) does not match the expected result (20). It should be Fail.
2Expected: 15 \| Actual: 5 \| Result: Fail		BExpected: 20 \| Actual: 10 \| Result: Fail \| Note: added instead of multiplied
3Copy the actual result exactly as the program displayed it, including spaces, capitals and punctuation.		CThe expected result was changed to match the actual result, which hides the bug. The expected result must stay 20 and the test should be marked Fail.
4When a test fails, keep the expected result unchanged and write a note describing what went wrong.		DThe actual result matches the expected result exactly, so the test is marked Pass.
5Expected: 20 \| Actual: 10 \| Result: Pass		EThe actual result does not match the expected result, so the test is marked Fail and a note should be added.
6Expected: 10 (changed from 20) \| Actual: 10 \| Result: Pass		FActual: Total: $12.50

Answer Key

Recording actual results and a pass or fail verdict

Section A: Quick Questions

B — No. Copy the actual result exactly: Total: 45

B — Pass

A — Fail

A — Leave it as 25 and record the Fail

A — Output was 20 but 25 expected. Total may be missing the last item

Section B: Match the Pairs

Expected: 15 | Actual: 15 | Result: Pass → The actual result matches the expected result exactly, so the test is marked Pass.

Expected: 15 | Actual: 5 | Result: Fail → The actual result does not match the expected result, so the test is marked Fail and a note should be added.

Copy the actual result exactly as the program displayed it, including spaces, capitals and punctuation. → Actual: Total: $12.50

When a test fails, keep the expected result unchanged and write a note describing what went wrong. → Expected: 20 | Actual: 10 | Result: Fail | Note: added instead of multiplied

Expected: 20 | Actual: 10 | Result: Pass → The result is marked Pass even though the actual result (10) does not match the expected result (20). It should be Fail.

Expected: 10 (changed from 20) | Actual: 10 | Result: Pass → The expected result was changed to match the actual result, which hides the bug. The expected result must stay 20 and the test should be marked Fail.

Section C: Definitions

Pass or Fail — Copy the actual result exactly as the program gave it, then mark Pass only if it matches the expected result, otherwise Fail. Never change the expected result to fit, and add a note for fails.

Section D: Fill in the Blanks

expected = 5
actual = add(2, 3)
if actual == expected: print("Pass")

v = "Pass" if actual == expected else "Fail"

if actual != expected:
    print("Fail: got", actual, "want", 
expected)

actual = add(2, 3)
print("Actual:", actual)

expected = 5
actual = add(2, 2)
if actual != expected: print("Fail")

Section E: Spot the Error

A — The expected result must be worked out before the test and kept fixed. Copying the actual result into expected makes the test pass automatically (and actual does not exist yet). It should be expected = 20.

C — A single = assigns a value, so it cannot compare the actual and expected results. Use == to check for a match: if actual == expected:

C — Pass means the actual result matches the expected result. With != the test would print PASS when the results are different. It should be if actual == expected:

C — The program must not change the expected result to fit what it produced. Doing that hides the failure (25 is not 30). This line should record the actual result: print("Actual:", actual)

D — This branch runs when actual matches expected, so the verdict must be Pass. It should be print("PASS"). The FAIL message belongs in the else branch.
