Testing

The library's tests

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

The suite checks the limits of every value, the reveal against known seeds, every field of a tampered proof, the codes of every die from the d2 to the d20, and the draw texts. In the monorepo, Infection holds the library at 100 % of covered mutants, and two fuzz targets feed the readers of the shop codes and of the draw texts with any input: what reads writes back to the same code or faces, everything else is refused with InvalidCode.

composer fuzz -- shop-code draw-text

The benchmarks measure the reveal and the verification of a box of ten d20 tables, and the codes written and read.

Testing code that uses the library

A seeded engine gives the same seed every run: PendingDraw::open(new Randomizer(new Xoshiro256StarStar(1))), or PendingDraw::restore() with a fixed seed. The faces a seed gives never change, since the dice of tilttek/dice rest on PHP's seeded engines. Results of chosen faces come from LootResult::ofFaces().
