Question

当我在DB::Connection()->getPdo();上进行尝试/捕获时，我收到错误尚未设置外观根。我认为Schema外观正在发生在我尝试添加try / catch之前。当然，测试目录在app目录之外，我觉得它与它有关，但我还没有成功搞清楚。

以下是发生这种情况的测试类：

<?php

namespace Tests\Models;

use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\DB;
use App\Models\Discussion;
use App\User;
use Business\Database\Model;
use Illuminate\Database\Schema\Blueprint;
use Tests\TestCase;

class DiscussionModelTest extends TestCase
{
    /**
     * Create the tables this model needs for testing.
     */
    public static function setUpBeforeClass()
    {
        try {
            DB::connection()->getPdo();
        } catch(\Exception $e) {
            die($e->getMessage());
        }

        Schema::create('discussions', function (Blueprint $table) {
            $table->integer('id');
            $table->integer('user_id');

            $table->foreign('user_id')->references('id')->on('users');
        });

        Schema::create('users', function (Blueprint $table) {
            $table->integer('id');
        });
    }
}

问题是你无法在setUpBeforeClass中执行此操作，因为许多内容都在setUp方法中运行。如果查看this order of run，您会看到setUpBeforeClass在setUp方法之前运行，而TestCase类在setUp方法中执行了很多操作。它看起来像这样：

protected function setUp()
{
    if (! $this->app) {
        $this->refreshApplication();
    }

    $this->setUpTraits();

    foreach ($this->afterApplicationCreatedCallbacks as $callback) {
        call_user_func($callback);
    }

    Facade::clearResolvedInstances();

    Model::setEventDispatcher($this->app['events']);

    $this->setUpHasRun = true;
}

所以你要做的就是用自己的实现创建自己的setUp和tearDown方法，如下所示：

protected function setUp()
{
   parent::setUp();
   // your code goes here
}

protected function tearDown()
{
   parent::tearDown();
   // your code goes here
}

对于其他对我使用Capsule工作的其他方法感到好奇的人，这里是代码。这适用于setUpBeforeClass()和setUp()。这可能而且应该更抽象，但这是它的要点。

use Illuminate\Database\Capsule\Manager as Capsule;

class DiscussionModelTest extends TestCase
{
    /**
     * Create the tables this model needs for testing.
     */
    public static function setUpBeforeClass()
    {
        $capsule = new Capsule;

        $capsule->addConnection([
            'driver' => 'sqlite',
            'database' => ':memory:',
            'prefix' => '',
        ]);

        $capsule->setAsGlobal();

        $capsule->bootEloquent();

        Capsule::schema()->create('discussions', function (Blueprint $table) {
            $table->integer('id');
            $table->integer('user_id');

            $table->foreign('user_id')->references('id')->on('users');
        });

        Capsule::schema()->create('users', function (Blueprint $table) {
            $table->integer('id');
        });

        // Seed the faux DB
        Model::unguard();

        User::create([
            'id' => 13
        ]);

        Discussion::create([
            'id' => 5,
            'user_id' => 13
        ]);
    }
}
