我有一个问题,我通过PHPunit在laravel 5.4中运行一些测试
我有一个测试类,我已经删除了一堆其他的东西,所以它实际上看起来像
<?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.
}
}
<?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');
});
}
}
但是,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 – 即使在作曲家du之后也是如此

有没有人知道为什么会发生这种情况,以及我如何解决它？可能值得添加我已尝试更改列名等,同样的问题正在发生
谢谢
UPDATE
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up之前down方法会运行？
更新2
似乎上面的发现是由于列没有首先创建,如果我抑制该错误,原始错误出现该列不存在 – 这表明迁移无法创建它.
解决方法:
根据laravel文档
Dropping or modifying multiple columns within a single migration while using a sqlite database is not supported.
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.
你可以像这样分开每个语句：
/**
* 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');
});
}
