Laravel/PHPUnit 的 Github 操作错误

Question

我使用 PHPUnit 进行 laravel unit/feature 测试的 github 操作出现错误。我的测试在本地通过。这是错误：

1) Tests\Feature\ClientControllerTest::test_clients_index_page_is_rendered
Illuminate\Database\QueryException: SQLSTATE[HY000]: General error: 1 Cannot add a NOT NULL column with default value NULL (SQL: alter table "users" add column "role_id" integer not null)

可能是我没有完全理解测试的工作方式，但我正在使用内存中的 sqllite 数据库进行测试。我有一个针对用户 table 的迁移，然后是在创建角色 table 之后向用户 table 添加 role_id 的另一个迁移。

不理解为什么在 test_clients_index_page_is_rendered 测试期间出现错误，因为此时数据库应该已经启动并填充。

我不知道是不是因为角色 table 没有填充数据，它是用户 table 的外键。我认为这也会在本地失败，因为我仍在使用内存数据库。我有一个播种机来填充角色，但我不会在测试中的任何地方调用它。不确定我是否需要这样做，或者在哪里做？

这里是错误中提到的测试：

namespace Tests\Feature;

use Tests\TestCase;
use App\Models\Role;
use App\Models\User;
use Illuminate\Support\Facades\Artisan;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Foundation\Testing\RefreshDatabase;

class ClientControllerTest extends TestCase
{
    use RefreshDatabase;

    protected $user;

    public function setup() :void
    {
        parent::setUp();
        $this->user = User::factory()->create();
    }

    public function test_clients_index_page_is_rendered()
    {
        $this->actingAs($this->user);
        $response = $this->get('/clients');
        $response->assertStatus(200);
    }

以下是我认为也可能导致问题的相关迁移：

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('first_name');
            $table->string('last_name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
            $table->softDeletes();
        });
    }
}

然后添加角色table，然后是外键：

 Schema::table('users', function (Blueprint $table) {
            $table->foreignIdFor(Role::class)->after('password');
        });

我什至不知道如何解决这个问题，因为它在本地发生。任何帮助将不胜感激。

如果有帮助，请查看完整跟踪：

更新

添加我的用户工厂：

namespace Database\Factories;

use Illuminate\Support\Str;
use Illuminate\Database\Eloquent\Factories\Factory;


class UserFactory extends Factory
{
    public function definition()
    {
        return [
            'first_name' => $this->faker->firstName,
            'last_name' => $this->faker->lastName,
            'phone' => $this->faker->unique()->numerify('###-###-####'),
            'email' => $this->faker->unique()->safeEmail,
            'email_verified_at' => now(),
            'password' => 'yIXUNpkjO0rOQ5byMi', 
            'remember_token' => Str::random(10),
            'role_id' => rand(1,4)
        ];
    }
}

Answer 1

如您在堆栈跟踪中所见，在迁移步骤中抛出异常。

发生这种情况是因为您将 not null 列添加到 table，这通常是不可能的。 SQLite 不知道应该为 table 中已有的记录设置什么值 role_id，因此它会阻止您执行此操作。

您可以将默认值添加到 role_id，或将其移至初始迁移。
