我正在为一个客户端开发一个应用程序，但在测试存储库时遇到了麻烦。
要将存储库绑定到模型，我有以下代码：

<?php

namespace FD\Repo;

use App;
use Config;

/**
 * Service Provider for Repository
 */
class RepoServiceProvider extends \Illuminate\Support\ServiceProvider
{
    public function register()
    {
        $app = $this->app;

        $app->bind('FD\Repo\FactureSst\FactureSstInterface', function ($app) {
            return new FactureSst\EloquentFactureSst(App::make('FactureSst'), new \FD\Service\Cache\LaravelCache($app['cache'], 'factures_sst', 10));
        });
    }
}

然后，存储库扩展一个抽象类，其中包含来自雄辩的ORM的函数（find、where、all等）。）。存储库的代码如下所示：

<?php

namespace FD\Repo\FactureSst;

use Illuminate\Database\Eloquent\Model;
use FD\Repo\AbstractBaseRepo;
use FD\Repo\BaseRepositoryInterface;
use FD\Service\Cache\CacheInterface;
use Illuminate\Support\Collection;

class EloquentFactureSst extends AbstractBaseRepo implements BaseRepositoryInterface, FactureSstInterface
{
    protected $model;
    protected $cache;

    public function __construct(Model $resource, CacheInterface $cache)
    {
        $this->model = $resource;
        $this->cache = $cache;
    }

    /**
     * Retrieve factures with the given SST and BDC IDs.
     *
     * @param int $sst_id
     * @param int $bdc_id
     * @return \Illuminate\Support\Collection
     */
    public function findWithSstAndBdc($sst_id, $bdc_id)
    {
        $return = new Collection;

        $factures = $this->model->where('id_sst', $sst_id)
            ->whereHas('facture_assoc', function ($query) use ($bdc_id) {
                $query->where('id_bdc', $bdc_id);
            })
            ->get();

        $factures->each(function ($facture) use (&$return) {
            $data = [
                'facture_id'   => $facture->id,
                'facture_name' => $facture->num_facture,
                'total_dsp'    => $facture->total_dsp(),
                'total_tradi'  => $facture->total_tradi()
            ];

            $return->push($data);
        });

        return $return;
    }
}

为了测试对数据库的调用，我使用Mockery，因为对数据库的调用太长了。下面是我的测试类：

<?php namespace App\Tests\Unit\Api\FactureSst;

use App;
use FactureSst;
use Illuminate\Database\Eloquent\Collection;
use Mockery as m;
use App\Tests\FdTestCase;

class FactureSstTest extends FdTestCase
{
    /**
     * The primary repository to test.
     */
    protected $repo;

    /**
     * Mocked version of the primary repo.
     */
    protected $mock;

    public function setUp()
    {
        parent::setUp();
        $this->repo = App::make('FD\Repo\FactureSst\FactureSstInterface');
        $this->mock = $this->mock('FD\Repo\FactureSst\FactureSstInterface');
    }

    public function tearDown()
    {
        parent::tearDown();
        m::close();
    }

    public function mock($class)
    {
        $mock = m::mock($class);
        $this->app->instance($class, $mock);
        return $mock;
    }

    public function testFindingBySstAndBdc()
    {
        $this->mock->shouldReceive('where')->with('id_sst', 10)->once()->andReturn($this->mock);
        $this->mock->shouldReceive('whereHas')->with('facture_assoc')->once()->andReturn($this->mock);
        $this->mock->shouldReceive('get');

        $result = $this->repo->findWithSstAndBdc(30207, 10);
        $this->assertEquals($result, new \Illuminate\Support\Collection);
        $this->assertEquals($result->count(), 0);
    }
}

正如您在测试中看到的，我只是尝试调用函数并确保函数正确链接。然而，我不断得到一个错误，说：
App\Tests\Unit\API\FactureSst\FactureSstTest：：testFindingBySstAndBdc Mockery\Exception\InvalidCountException：方法，其中来自Mockery_0_FD_Repo_FactureSst_FactureSstInterface的（“id_sst”，10）应被精确调用1次，但被调用0次。
请有人能帮助我理解为什么这是不工作，以及如何修复它。对不起，代码是法语，该应用程序是为一个法国客户。
先谢谢你了。
