Word scramble
Unscramble the letters and write each key term on the line.
1
LTPAN(AVIRERBI)
Debugging tool: print a variable at key points, then compare each value with your trace table of what it should be. The first mismatch shows where the bug is.
2
ITERPKONBA
A marker set on a line of code (click beside the line number) that pauses the program there in debug mode, so you can inspect variables and step through the code.
3
TESP OURHTHG
Run paused code one line at a time using step over, step into or step out, while the watch panel shows each variable change, to find where a value goes wrong.
4
ENDETS OOPL
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.
5
YODABNRU SEVLAU
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.
6
SETT AADT
Values chosen to test each validation rule: empty for existence, text for type, and values just inside and just outside range limits, each with an expected result.
7
ETTS ASCE
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.
8
TERSSA
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.

1LTPAN(AVIRERBI) → print(variable) — Debugging tool: print a variable at key points, then compare each value with your trace table of what it should be. The first mismatch shows where the bug is.
2ITERPKONBA → breakpoint — A marker set on a line of code (click beside the line number) that pauses the program there in debug mode, so you can inspect variables and step through the code.
3TESP OURHTHG → step through — Run paused code one line at a time using step over, step into or step out, while the watch panel shows each variable change, to find where a value goes wrong.
4ENDETS OOPL → nested loop — 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.
5YODABNRU SEVLAU → Boundary values — 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.
6SETT AADT → test data — Values chosen to test each validation rule: empty for existence, text for type, and values just inside and just outside range limits, each with an expected result.
7ETTS ASCE → test case — 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.
8TERSSA → assert — Checks a condition is True, like assert add(2, 3) == 5. If the result is not what you expected, it raises an AssertionError, so test cases can run automatically.
