Amalan Terbaik Pengujian PHPUnit

Amalan Terbaik Pengujian PHPUnit dalam XOOPSUjian adalah penting untuk memastikan kualiti kod, mencegah regresi, dan membolehkan pemfaktoran semula yang yakin.## Memasang PHPUnit

bash
# Using Composer
composer require --dev phpunit/phpunit ^9.0

# Run tests
./vendor/bin/phpunit

phpunit.xml Konfigurasi

xml
<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="tests/bootstrap.php"
         colors="true"
         verbose="true">
    <testsuites>
        <testsuite name="Unit">
            <directory>tests/unit</directory>
        </testsuite>
        <testsuite name="Integration">
            <directory>tests/integration</directory>
        </testsuite>

    <coverage processUncoveredFiles="true">

            <directory suffix=".php">class</directory>
        </include>
        <report>

Ujian Unit Penulisan

php
<?php
namespace XOOPS\Module\Mymodule\Tests\Unit;

use PHPUnit\Framework\TestCase;
use XOOPS\Module\Mymodule\Service\UserService;

class UserServiceTest extends TestCase
{
    private $userService;
    private $mockRepository;

    protected function setUp(): void
    {
        parent::setUp();
        $this->mockRepository = $this->createMock(
            \XOOPS\Module\Mymodule\Repository\UserRepositoryInterface::class
        );
        $this->userService = new UserService($this->mockRepository);
    }

    public function testRegisterSuccess()
    {
        // Arrange
        $this->mockRepository->expects($this->once())
            ->method('findByUsername')
            ->willReturn(null);

        $this->mockRepository->expects($this->once())
            ->method('save')
            ->willReturn(1);

        // Act
        $result = $this->userService->register('user', 'test@test.com', 'pass');

        // Assert
        $this->assertNotNull($result);
    }

    public function testRegisterDuplicate()
    {
        // Arrange
        $existingUser = new \stdClass();
        $this->mockRepository->expects($this->once())
            ->method('findByUsername')
            ->willReturn($existingUser);

        // Act & Assert
        $this->expectException(\Exception::class);
        $this->userService->register('user', 'test@test.com', 'pass');
    }
}
?>

Menguji Objek Data

php
<?php
class UserDTOTest extends TestCase
{
    public function testDTOCreation()
    {
        $user = new User();
        $user->setId(1)
            ->setUsername('testuser')
            ->setEmail('test@test.com');

        $dto = new UserDTO($user);

        $this->assertEquals(1, $dto->getId());
        $this->assertEquals('testuser', $dto->getUsername());
    }

    public function testDTOToArray()
    {
        $user = new User();
        $user->setId(1)->setUsername('testuser');

        $dto = new UserDTO($user);
        $array = $dto->toArray();

        $this->assertIsArray($array);
        $this->assertEquals(1, $array['id']);
    }
}
?>

Liputan Kod

bash
# Generate coverage report
./vendor/bin/phpunit --coverage-html coverage

# View coverage percentage
./vendor/bin/phpunit --coverage-text

Amalan Terbaik- Tulis satu ujian setiap method/scenario

Gunakan nama ujian deskriptif
Ikut corak Susun-Bertindak-Tegaskan
Olok-olok kebergantungan luar
Pastikan ujian fokus dan bebas
Sasarkan untuk liputan kod 80%+
Uji keadaan ralat
Uji kes sempadan## Organisasi Ujian
