Laravel Unit Testing

• 建立feature test:

$ php artisan make:test UserTest

• 建立unit test:

$ php artisan make:test UserTest --unit

• 執行測試:

$ php artisan test

Unit Test

<?php
namespace Tests\Unit;
use Tests\TestCase;
use App\Repositories\UserRepository;
class UserTest extends TestCase
{
    
    /**
     * @dataProvider getNameProvider
     */
    public function testGetName($id, $name)
    {
        $userRepo = new UserRepository();
        $this->assertEquals($name, $userRepo->getName($id));
    }
    public function getNameProvider() {
        return [
            [1, 'Vic'],
            [2, 'Allen'],
        ];
    }
}

• 執行$php artisan test後，會將所有test開頭的method都當作進入點做測試，也就是說method命名可以用testXXX 或 test_xxx等等。
• @dataProvider是用來定義method輸入參數用的。
  意思其實等同於:

testGetName(1, 'Vic')
testGetName(2, 'Allen')

Feature Test

<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
class UserTest extends TestCase
{
    
    public function testGetName()
    {
        $response = $this->get('api/user/name?id=1');
        $response->assertStatus(200);
    }
}
