Testing

The library's tests

composer install
vendor/bin/phpunit --no-configuration tests

The suite covers the days and their days of the week on both sides of 1970, the author's today in their timezone, the goals and their refusals, the four curves, the writing days and the dates set aside, the plans — first day, missed days, days ahead, today's count, rounding that adds up, days of weight 0, days without writing, before the start, a goal reached, past the deadline —, logging, taking back and correcting counts, the goal reached told once, erasure, and the stores in memory through GoalStoreTestCase and LogStoreTestCase, the contracts any store passes. tests/Benchmark/PlannerBench.php measures a plan of a month and one of ten years. In the monorepo, Infection holds the library at 100 % of covered mutants.

Testing code that logs counts

Build WritingGoals with the stores in memory, a clock you move — Symfony\Component\Clock\MockClock — and a dispatcher that writes down its events:

$clock = new MockClock('2026-11-03 03:30:00', 'UTC');
$goals = new WritingGoals(new InMemoryGoalStore(), new InMemoryLogStore(), $clock, $dispatcher);
$goals->save($goal);

self::assertSame('2026-11-02', $goals->plan($goal->id)->today->toString()); // in America/Montreal

To test a plan alone, call Planner::plan() with a Progress::fromArray() and the day you choose.
