使用 PHPUnit 和 Pest、工厂、数据库测试、模拟以及覆盖率目标进行 Laravel 的测试驱动开发。
使用 PHPUnit 和 Pest 为 Laravel 应用程序进行测试驱动开发,覆盖率(单元 + 功能)达到 80% 以上。
根据范围选择层级:
RefreshDatabase(每次测试运行运行一次迁移,然后在支持时将每个测试包装在事务中;内存数据库可能每次测试重新迁移)DatabaseTransactionsDatabaseMigrations将 RefreshDatabase 作为触及数据库的测试的默认选择:对于支持事务的数据库,它每次测试运行运行一次迁移(通过静态标志)并将每个测试包装在事务中;对于 :memory: SQLite 或不支持事务的连接,它在每次测试前进行迁移。当模式已迁移且仅需要每次测试回滚时使用 DatabaseTransactions。

Http::fake() 隔离外部 APIHttp::assertSent() 断言出站负载pcov 或 XDEBUG_MODE=coveragephp artisan testvendor/bin/phpunitvendor/bin/pestphpunit.xml 设置 DB_CONNECTION=sqlite 和 DB_DATABASE=:memory: 以进行快速测试use Illuminate\Support\Facades\Gate;
$this->assertTrue(Gate::forUser($user)->allows('update', $project));
$this->assertFalse(Gate::forUser($otherUser)->allows('update', $project));
使用 Inertia.js 时,使用 Inertia 测试辅助函数来断言组件名称和属性。
use App\Models\User;
use Inertia\Testing\AssertableInertia;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;
final class DashboardInertiaTest extends TestCase
{
use RefreshDatabase;
public function test_dashboard_inertia_props(): void
{
$user = User::factory()->create();
$response = $this->actingAs($user)->get('/dashboard');
$response->assertOk();
$response->assertInertia(fn (AssertableInertia $page) => $page
->component('Dashboard')
->where('user.id', $user->id)
->has('projects')
);
}
}
优先使用 assertInertia 而非原始 JSON 断言,以保持测试与 Inertia 响应一致。
