Warm-up: Spot the Bug — the fix that broke something else
The regression: a change that passed every test somebody thought to
write, and failed the one nobody did
Compare and name it: Testing and Regression — edge cases, and
the test you write before the fix
Project milestone: tests over the parts of your team’s build that
you did not personally write
Last twenty minutes: finish and hand in The Maintenance Sprint —
the fix, the extension, the tests, a change log from each of you, and
the note you leave behind
Things to do before our next class
Milestone: a written testing plan for your project, naming who
tests what and when.
Journal: the edge case you did not think of, and who found it.
