【问题描述】：

我正在尝试创建一个模拟对象并将其传递给构造函数。我收到了错误

根据the docs，这应该可以工作。

用户类

class Users

    public function __construct(?string $secret, UsersApi $usersApi = null)
    
    

UsersTest 类

use Mockery\Adapter\Phpunit\MockeryTestCase;

class UsersTest extends MockeryTestCase

    public function testGetUser_ItShouldThrowAnExceptionIfUserDoesNotExist()
    
        $this->expectException(UserNotFoundException::class);
        $this->expectExceptionMessage("User with id, email, or username [e-mail] not found");

        $usersApi = Mockery::mock('UsersApi');
        $usersApi->shouldReceive('get')
            ->andThrow(new UserNotFoundException("User with id, email, or username [e-mail] not found"));

        $usersClient = new Users(null, $usersApi);
    

【参考方案1】：

啊，我刚刚想通了。我需要使用完整的命名空间。

即

替换

$usersApi = Mockery::mock('UsersApi');

与

$usersApi = Mockery::mock('Foo\Api\UsersApi');
