Question

我有一个问题，我通过phpunit在laravel 5.4中运行一些测试

我使用内存sqlite数据库进行测试

我有一个测试课程，我已经删除了其他一些东西，因此它实际上看起来像

<?php

namespace Tests\Unit;

use App\User;
use App\Order;
use Tests\TestCase;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class OrderTest extends TestCase
{
    use DatabaseMigrations;

    /** @test */
    function can_update_status()
    {
         // This is empty, it fails on this test because its alphabetically the first test in the whole suite.
    }
}

我最近创建了一个新的迁移，它添加了＆＃34;付费＆＃34;柱

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class AddStatusToOrders extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('orders', function (Blueprint $table) {
            $table->dropColumn('completed');
            $table->boolean('paid')->default(0);
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('orders', function (Blueprint $table) {
            $table->boolean('completed')->default(0);
            $table->dropColumn('paid');
        });
    }
}

然而，每当我运行此测试时，我都会收到一条错误消息，指出付费列不存在 - 即使在composer du

之后也是如此

有没有人知道为什么会这样，以及我如何解决它？可能值得添加我尝试更改列名等，同样的问题正在发生

由于

更新

如果我注释掉向下迁移中的行，例如$table->dropColumn('paid');

然后它继续运行 - 但是我很难理解为什么在运行之前down方法会运行？

更新2

上面的结果似乎是由于列没有首先创建，如果我抑制了该错误，原始错误会显示该列不存在 - 这表明迁移无法创建它。

Answer 1

根据laravel文件

不支持在使用SQLite数据库时删除或修改单个迁移中的多个列。

虽然您没有尝试修改或删除多个列，但您尝试在一次迁移中删除并创建，在这两种情况下都会执行ALTER TABLE查询，此处的问题是limitations of ALTER TABLE query of sqlite。

您可以将每个语句分开：

 /**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::table('orders', function (Blueprint $table) {
        $table->dropColumn('completed');
    });

   Schema::table('orders', function (Blueprint $table) {
         $table->boolean('paid')->default(0);
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('orders', function (Blueprint $table) {
        $table->boolean('completed')->default(0);
    });
   Schema::table('orders', function (Blueprint $table) {
     $table->dropColumn('paid');
    });
}

PHPUnit似乎没有运行Laravel Migration
