Laravel 5重新安装测试之间的单元测试数据库

Question

我从一个种子数据库开始,我试图在Laravel 5中的单元测试之间重新设置数据库.在Laravel 4中我理解你可以简单地使用Illuminate\Support\Facades\Artisan并运行命令

Artisan::call('migrate');
Artisan::call('db:seed');

或者你认为可以这样做:

$this->seed('DatabaseSeeder');

在每次测试之前.在Laravel 5中,这似乎已被替换为

use DatabaseMigrations;

要么

use DatabaseTransactions;

我已经尝试使用这些并且设法获得测试以迁移数据库; 但是,它实际上并没有重新设置表格中的数据.我已经阅读了几个论坛抱怨这个,并尝试了几种不同的方法从TestCase和每个测试中调用这些...添加

    $this->beforeApplicationDestroyed(function () {
        Artisan::call('migrate');
        Artisan::call('migrate:reset');
        Artisan::call('db:seed');
        DB::disconnect();
    });

到TestCase.php tearDown()......

我也尝试过添加

$this->createApplication();

从TestCase.php的每个测试中调用的方法

有时它只是完全擦掉我的桌子.我在Laravel的网站或博客中找到的任何内容似乎都无效.部分原因可能是因为我可能在Laravel 5中尝试Laravel 4方法.在Laravel 5中有没有办法做到这一点？

我的testcase.php代码如下:

<?php

use Illuminate\Support\Facades\Artisan as Artisan;

class TestCase extends Illuminate\Foundation\Testing\TestCase{

    use Illuminate\Foundation\Testing\WithoutMiddleware;
    use Illuminate\Foundation\Testing\DatabaseMigrations;
    use Illuminate\Foundation\Testing\DatabaseTransactions;

    protected $baseUrl = 'http://localhost';


    public function initializeTests(){

        $this->createApplication();

       Artisan::call('migrate');
       $this->artisan('migrate');
       Artisan::call('db:seed');
       $this->artisan('db:seed');
       $this->seed('DatabaseSeeder');
       $this->session(['test' => 'session']);
       $this->seed('DatabaseSeeder');

    }

    public function tearDown()
    {
      Mockery::close();
      Artisan::call('migrate:reset');
      $this->artisan('migrate:reset');
      Artisan::call('migrate:rollback');
      $this->artisan('migrate:rollback');
      Artisan::call('migrate');
      $this->artisan('migrate');
      Artisan::call('db:seed');
      $this->artisan('db:seed');
      $this->seed('DatabaseSeeder');
      DB::disconnect();

         foreach (\DB::getConnections() as $connection) {
             $connection->disconnect();
         }

      $this->beforeApplicationDestroyed(function () {
         Artisan::call('migrate:reset');
         $this->artisan('migrate:reset');
         Artisan::call('migrate:rollback');
         $this->artisan('migrate:rollback');
         Artisan::call('migrate');
         $this->artisan('migrate');
         Artisan::call('db:seed');
         $this->artisan('db:seed');
         $this->seed('DatabaseSeeder');
         DB::disconnect();
         foreach (\DB::getConnections() as $connection) {
             $connection->disconnect();
         }
      });

       $this->flushSession();
       parent::tearDown();


    }

    public function getConnection()
    {
        $Connection = mysqli_connect($GLOBALS['DB_DSN'], $GLOBALS['DB_USERNAME'], $GLOBALS['DB_PASSWORD'], $GLOBALS['DB_DATABASE']);
        $this->createDefaultDBConnection();
        return $this->Connection;
    }

    public function createApplication()
    {
        $app = require __DIR__.'/../bootstrap/app.php';

        $app->make(Illuminate\Contracts\Console\Kernel::class)->bootstrap();

        return $app;
    }

    /**
     * Magic helper method to make running requests simpler.
     *
     * @param $method
     * @param $args
     * @return \Illuminate\Http\Response
     */
    public function __call($method, $args)
    {
        if (in_array($method, ['get', 'post', 'put', 'patch', 'delete']))
        {
            return $this->call($method, $args[0]);
        }

        throw new BadMethodCallException;
    }

    /**
     * Create a mock of a class as well as an instance.
     *
     * @param $class
     * @return \Mockery\MockInterface
     */
    public function mock($class)
    {
        $mock = Mockery::mock($class);

        $this->app->instance($class, $mock);

        return $mock;
    }

}

我的测试看起来像

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\Artisan;

class CustomerRegistrationControllerTest extends TestCase
{

    use DatabaseMigrations;

    protected static $db_inited = false;

    protected static function initDB()
    {
        echo "\n---Customer Registration Controller Tests---\n"; // proof it only runs once per test TestCase class
        Artisan::call('migrate');
        Artisan::call('db:seed');
    }

    public function setUp()
    {

        parent::setUp();

        if (!static::$db_inited) {
            static::$db_inited = true;
            static::initDB();
        }

//        $this->app->refreshApplication();
        $this->artisan('migrate:refresh');
        $this->seed();
        $this->seed('DatabaseSeeder');

        $this->initializeTests();

);

    }


    public function testSomething()

    {


        $this->Mock
            ->shouldReceive('destroy')
            ->with('1')
            ->andReturn();


        $this->RegistrationController->postRegistration();
//      $this->assertResponseStatus(200);

    }

}

为什么不创建自己的命令，例如 db:reset。此命令要么截断所有表，要么删除/创建架构，然后迁移。

在您的测试中，您可以使用：$this->call('db:reset')在测试之间
