Testing

Compose Cbox\Nexus\Testing\InteractsWithNexus in your test case for a fully in-memory engine — no dataset, no HTTP. The package dogfoods these same fakes.

use Cbox\Nexus\Testing\InteractsWithNexus;
use Cbox\Nexus\Enums\NexusStatus;
use Cbox\Geo\ValueObjects\SubdivisionCode;

$engine = $this->nexusEngine(
    thresholds: ['US-CA' => $this->salesThreshold(500_000)],
    activity:   ['US-CA' => $this->activity(600_000)],
);

expect($engine->evaluate(new SubdivisionCode('US-CA'))->status)
    ->toBe(NexusStatus::Triggered);

The fakes — ArrayNexusThresholdSource, ArraySalesLedger, ArrayPhysicalNexus, ArrayNexusRegistrations — are plain array-backed implementations you can also use outside tests.
