Laravel在测试时创建数据库

Question

我正在尝试运行单元测试并在安装过程中创建数据库.出于某种原因,我收到了错误Unknown database 'coretest'.如果我手动创建数据库并运行测试,那么我得到Can't create database 'coretest'; database exists.

drop database语句现在只适用于create database.

这是我的setUP和tearDown方法:

class TestCase extends Illuminate\Foundation\Testing\TestCase {
    /**
     * Default preparation for each test
     */

    public function setUp() {
        parent::setUp();

        DB::statement('create database coretest;');
        Artisan::call('migrate');
        $this->seed();
        Mail::pretend(true);
    }

    public function tearDown() {
        parent::tearDown();
        DB::statement('drop database coretest;');
    }
}

您收到此错误的原因仅仅是因为laravel尝试连接到config中指定的数据库,该数据库不存在.

解决方案是从设置构建您自己的PDO连接,而不指定数据库(PDO允许这样)并CREATE DATABASE $dbname使用它运行语句.

我们使用这种方法在我们的项目中进行测试没有任何问题.

这里有一些代码:

<?php

/**
 * Bootstrap file for (re)creating database before running tests
 *
 * You only need to put this file in "bootstrap" directory of the project
 * and change "bootstrap" phpunit parameter within "phpunit.xml"
 * from "bootstrap/autoload.php" to "bootstap/testing.php"
 */

$testEnvironment = 'testing';

$config = require("app/config/{$testEnvironment}/database.php");

extract($config['connections'][$config['default']]);

$connection = new PDO("{$driver}:user={$username} password={$password}");
$connection->query("DROP DATABASE IF EXISTS ".$database);
$connection->query("CREATE DATABASE ".$database);

require_once('app/libraries/helpers.php');

// run migrations for packages
foreach(glob('vendor/*/*', GLOB_ONLYDIR) as $package) {
    $packageName = substr($package, 7); // drop "vendor" prefix
    passthru("./artisan migrate --package={$packageName} --env={$testEnvironment}");
}
passthru('./artisan migrate --env='.$testEnvironment);

require('autoload.php'); // run laravel's original bootstap file
