最小化工厂的测试？

Question

目前我在Test类中使用了很多工厂factory(Something::class)，有没有办法减少到1，所以我只能在测试方法中使用$user = factory(User::class)->create(); $token = factory(Token::class)->create([ 'user_id' => $user->id, ]); $provider = factory(Provider::class)->create([ 'user_id' => $user->id, 'token_id' => $token->id, ]); $something = factory(Something::class)->create([ 'provider_id' => $provider->id, ]); // Now test with $something ？

原因我使用了很多因为我必须传递一些外键。

Answer 1

您可以使用以下语法：

$factory->define(Something::class, function ($faker) {
    return [
        'title' => $faker->title,
        'content' => $faker->paragraph,
        'provider_id' => function () {
            return factory(Provider::class)->create()->id;
        }
    ];
});

$factory->define(Provider::class, function ($faker) {
    $user = factory(User:class)->create();
    return [
        'user_id' => $user->id,
        'token_id' => function () {
            return factory(Token::class)->create(['user_id' => $user->id])->id;
        }
    ];
});

然后在测试中你只能使用：

$something = factory(Something::class)->create();

请注意，根据您的需要，它可能会导致一些副作用 - 例如，在使用提供者工厂时，将始终根据您的测试创建可能正常或不正常的用户。当然，如果需要，你总是可以创建帮助方法来包装你展示的所有方法，只返回一些东西，然后在你的测试中你只能使用：

$something = $this->createSomething();
