Snapshot testing with PHPUnit

use Spatie\Snapshots\MatchesSnapshots;

class OrderTest
{
    use MatchesSnapshot;

    class test_it_casts_to_json()
    {
        $orderId = new Order(1);

        $this->assertMatchesJsonSnapshot($order->toJson());
    }
}

Again great work by the folks at Spatie:

The difference between a classic assertEquals and an assertMatchesSnapshot is that you don’t write the expectation yourself when snapshot testing. When a snapshot assertion happens for the first time, it creates a snapshot file with the actual output, and marks the test as incomplete. Every subsequent run will compare the output with the existing snapshot file to check for regressions.
