Unit 3, Day 12

Agenda

1. Warm-up: Trace It
2. The Toolbox, day 3: the file tool, plus a test plan per function from Writing a Test Plan
3. Hand-worked cases only — a test whose expected value came from running the code is not a test
4. Read the criteria on The Toolbox now, before the note is written — two of them are about somebody else being able to use this, which is what tomorrow tests

Things to do before our next class

• All four tested against values you worked out yourself.
