Testing

The library's tests

The suite tests/Unit builds a shirt template — versions, sizes and colours, an excluded combination, two faces — and a design in two languages, and checks every product of its plan: SKUs, prices, channels, the artwork chosen on each zone, names, attributes and photos. Every refusal is checked with its message, at and past each limit. Templates and designs are written to JSON and read back equal.

From the monorepo root:

vendor/bin/phpunit packages/commerce-product-template/tests

The library is held to 100 % covered mutation score by Infection.

Fuzz targets

sku-pattern parses patterns nobody wrote and renders those it accepts; template-array reads templates from JSON nobody wrote. Each accepts the input or refuses it with InvalidDefinition, and nothing else:

composer fuzz

Benchmark

tests/Benchmark/VariantPlannerBench.php plans a template of 3 versions, 18 sizes and 50 colours for a design in two languages, 5 400 products, and reads a template back from its array.

Testing code that plans

Build small templates in a fixture and compare the SKUs a plan gives, rather than counting products:

$skus = array_map(static fn (Variant $variant): string => $variant->sku, new VariantPlanner()->plan($template, $design));

self::assertSame(['NAQ001FOMBK', 'NAQ001FOMPK'], $skus);
