- 4. Word 1 of the term in 1 Down: ______, ________ and invalid ____ (6)
- 5. Word 5 of the term in 1 Down: ______, ________ and invalid ____ (4)
- 7. A loop inside another loop. When tracing, the inner loop completes all its repeats for each single repeat of the outer loop, so total passes = outer repeats x inner repeats. Word 1 of: ______ loop (6)
- 10. Checks a condition is True, like ______ add(2, 3) == 5. If the result is not what you expected, it raises an AssertionError, so test cases can run automatically. (6)

- 1. A good test set uses ______ ______ (typical values), ______ ______ (values at the edges of a range) and invalid ______ (values that should be rejected), so every path in an algorithm is checked. Word 2 of: ______, ________ and invalid ____ (8)
- 2. Debugging tool: print a ______ at key points, then compare each value with your trace table of what it should be. The first mismatch shows where the bug is. Word 2 of: print(________) (8)
- 3. A chosen input paired with the output you expect. Run the algorithm, record the actual output, then compare: if actual matches expected it passes, otherwise it fails. Word 2 of: ____ ____ (4)
- 6. Values chosen to ______ each validation rule: empty for existence, text for type, and values just inside and just outside range limits, each with an expected result. Word 1 of: ____ ____ (4)
- 8. Run paused code one line at a time using ______ over, ______ into or ______ out, while the watch panel shows each variable change, to find where a value goes wrong. Word 1 of: ____ through (4)
- 9. Test inputs at the edge of a condition. For age >= 18, test 17 (just below), 18 (exactly on) and 19 (just above) to check the algorithm picks the right path at the edge. Word 2 of: ________ ______ (6)
