Composing Macros

Macros can call other macros for layered behaviour
Most test assertion methods accept closures, making them composable
This removes repeated setup code and keeps tests focused on intent

use Illuminate\Support\Arr;
use Illuminate\Support\Facades\Http;
use Illuminate\Http\Client\Request;

Request::macro('hasGraphQLCall', function ($mutation, array $data) {
    $data = Arr::undot($data);
    $arguments = $this->data;

    if (!array_key_exists('variables', $arguments)) {
        return false;
    }

    if (array_intersect($data, $arguments['variables']) != $data) {
        return false;
    }

    return $this->hasHeader('Authorization', 'Bearer ' . config('services.api.token'))
        && $this->url() == config('services.api.url')
        && $this['operationName'] === $mutation;
});

Http::macro('assertGraphQLCall', function ($mutation, $data) {
    Http::assertSent(function (Request $request) use ($mutation, $data) {
        return $request->hasGraphQLCall($mutation, $data);
    });
});

Http::macro('sendsGraphQL', function () {
    Http::fake([
        config('services.api.url') => Http::response(['data' => (object) [
            'some' => 'data',
        ]]),
    ]);
});
