ORM独立的关系型数据库测试数据生成器。

用法

在为测试构建引导环境时定义一些通用规则

// $container points some application scope service locator
$container->set(\Lapaz\QuickBrownFox\Database\SessionManager::class, function() use ($container) {
    $fixtures = new \Lapaz\QuickBrownFox\FixtureManager();
    
    $fixtures->table('authors', function ($td) {
        $td->fixture('GoF')->define([
            [ 'name' => "Erich Gamma" ],
            [ 'name' => "Richard Helm" ],
            [ 'name' => "Ralph Johnson" ],
            [ 'name' => "John Vlissides" ],
        ]);
    });
    
    $fixtures->table('books', function ($td) {
        $td->generator('DesignPattern-N')->define(function($i) {
            return [
                'title' => 'Design Pattern ' . ($i + 1),
                'code' => sprintf('000-000-%03d', $i),
                // not needed: 'author_id' => ?
            ];
        });
    });
    
    // 'database' must be DBAL connection or PDO
    return $fixtures->createSessionManager($container->get('database'));
});

准备新的测试会话

use PHPUnit\Framework\TestCase;

class BookRepositoryTest extends TestCase
{
    protected $session;
    
    protected function setUp()
    {
        /** @var ContainerInterface $container */
        $this->session = $container->get(\Lapaz\QuickBrownFox\Database\SessionManager::class)->newSession();
    }
}

使用预定义的测试数据和生成器添加测试

    public function testFindBook()
    {
        $this->session->into('authors')->load('GoF');
        $this->session->into('books')->with('DesignPattern-N')->generate(10);
        
        $books = (new BookRepository($this->connection))->findAll();
        $this->assertCount(10, $books);
        $this->assertEquals("Design Pattern 1", $book[0]->getTitle());
        
        $this->assertNotNull($book[0]->getAuthor());
    }

注意：如果不存在，则非空外键约束将随机解决。

您可以使用内联测试数据而不是预定义的测试数据

        $this->session->into('authors')->load([
            [ 'name' => "Erich Gamma" ],
            [ 'name' => "Richard Helm" ],
            [ 'name' => "Ralph Johnson" ],
            [ 'name' => "John Vlissides" ],
        ]);

以及内联生成器

        $this->session->into('books')->with(function($i) {
            return [
                'title' => 'Design Pattern ' . ($i + 1),
                'code' => sprintf('000-000-%03d', $i),
            ];
        })->generate(10);

可以为数组形式的测试数据设置常见属性。

        $this->session->into('authors')->with([
            'specialist' => true,
            'rating' => function($i) { return 80 + $i * 5; },
        ])->load([
            [ 'name' => "Erich Gamma" ],
            [ 'name' => "Richard Helm" ],
            [ 'name' => "Ralph Johnson" ],
            [ 'name' => "John Vlissides" ],
        ]);

您可以在会话中重复添加额外数据。当下一个会话使用相同表时，这些数据将自动删除。

        $this->session->into('authors')->with([
            'specialist' => false,
            'rating' => function() { return mt_rand(30, 50); },
        ])->generate(6));

        $this->session->into('authors')->with([
            'specialist' => false,
            'rating' => function() { return mt_rand(30, 50); },
        ])->generate(6));

属性按从右到左的顺序覆盖。被覆盖的函数不会被评估，因此不会调用不必要的慢速计算。

        $this->session->into('books')->with('DesignPattern-N')->with([
            'title' => function($i) {
                return 'Design Pattern -2nd Edition- ' . ($i + 1);
            },
        ])->generate(10);

如果您不关心每个属性，可以这样做

        $this->session->into('books')->generate(100);

但是，当可能存在一些属性约束时，您可以定义表级别的生成器规则

    $fixtures->table('books', function ($td) {
        $td->defaults([
            'type' => function() {
                return mt_rand(1, 3); // books.type must be 1, 2 or 3
            }
        ]);
    });
