02What counts as reproducing it

The bar, written down before the run.

expected.reportedFailurecommitted with the case
Symptom
pluralize("olives", 1) produces 'olife'; the fix makes it produce 'olive'.
Expression
pluralize("olives", 1)
Reported output
"olife"
Where that came from
Read mechanically from the report's fenced code, SAME_LINE form: `pluralize("olives", 1) // "olife" (should be "olive")`.
