php - 为什么我使用 Mockery 会得到 NoMatchingExpectationException？

Question

我正在尝试为我的网络应用程序编写一些单元测试。我使用 Laravel 5.3 和 Mockery。

这是简化的代码:

class UserService
{
    protected $userRepository;

    public function __construct(IUserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function saveUserWithGeneratedPassword($user, $companyId, $isAdmin)
    {
        try {
            $user['password'] = $this->encryptUserPassword($this->createPassword());
            return $this->userRepository->saveUser($user, $companyId, $isAdmin);
        } catch (\Exception $e) {
            Log::error(
                'Exception occured while trying to create new user: ' . $e->__toString()
            );
            return false;
        }
    }
}

class UserRepository implements IUserRepository
{
    /**
     * @var User
     */
    private $model;

    /**
     * UserRepository constructor.
     *
     * @param User $model
     */
    public function __construct(User $model)
    {
        $this->model = $model;
    }

    /**
     * @param $user
     * @param $companyId
     * @param $isAdmin
     * @return static
     */
    public function saveUser($user, $companyId, $isAdmin)
    {
        $user = $this->model->create($user);
        $user->companies()
            ->attach($companyId, ['is_admin' => $isAdmin]);

        return $user;
    }
}

这是测试代码:

class UserPasswordResetTest extends TestCase {
    private $userService;

    public function setUp()
    {

        parent::setUp();

        $this->user = Mockery::mock('Eloquent', User::class)
            ->makePartial();

        $this->userRepository = Mockery::mock(IUserRepository::class);
        $this->app->instance(IUserRepository::class, $this->userRepository);

        $this->userRepository->shouldReceive('saveUser')
            ->withArgs(
                [
                    'userData',
                    'companyId',
                    'isAdmin'
                ]
            )
            ->andReturn($this->user);


        $this->userService = new UserService($this->userRepository, $this->passwordResetRepository);
    }

    public function tearDown()
    {
        parent::tearDown();
        Mockery::close();
    }

    public function testSaveUserWithGeneratedPassword()
    {
        $userData = [
            'first_name' => 'firstname',
            'last_name'  => 'lastname',
            'phone'      => '0123456789',
            'mobile'     => '0123456789',
            'locale'     => 'en',
            'email'      => 'best_email@ever.com',
            'is_active'  => '1',
            'password'   => 'password'
        ];

        $companyId = "1";
        $isAdmin = "0";


        $result = $this->userService->saveUserWithGeneratedPassword($userData, $companyId, $isAdmin);
        $this->assertInstanceOf(User::class, $result);
        $this->assertInternalType("string", $result->password);
    }
}

这是异常(exception)情况:

Mockery\Exception\NoMatchingExpectationException: No matching handler found for Mockery_... Either the method was unexpected or its arguments matched no expected argument list for this method

编辑

最后还是不行。我发现用户模拟的密码属性设置不正确。我删除了第二个断言并在 UserService 上注释掉了这一行:

$user['password'] = $this->encryptUserPassword($this->createPassword());

之后就可以了。当我删除注释行时，它再次失败。但是我也不能 mock 它，因为它是 SUT。

这是测试的当前代码片段:

public function testSaveUserWithGeneratedPassword()
{

    $companyId = '1';
    $isAdmin = '0';
    $email = 'best_email@ever.com';

    $userData = [
        'first_name' => 'firstname',
        'last_name'  => 'lastname',
        'phone'      => '0123456789',
        'mobile'     => '0123456789',
        'locale'     => 'en',
        'email'      => $email,
        'is_active'  => '1',
    ];

//        $this->user->shouldReceive('getAttribute')
//        ->with('password')
//        ->andReturn('$2y$10$2jZTKnkmYsF8rr3wqIy.m.e06p9wtIukIOv10gMSXKQ6T7ogkmECW');

    $this->userRepository->shouldReceive('saveUser')
        ->withArgs(
            [
                $userData,
                $companyId,
                $isAdmin
            ]
        )
        ->andReturn($this->user);

    $result = $this->userService->saveUserWithGeneratedPassword($userData, $companyId, $isAdmin);
    $this->assertInstanceOf(User::class, $result);
}

Answer 1

您使用这些参数定义对 saveUser 的预期调用:

->withArgs(
            [
                'userData',
                'companyId',
                'isAdmin'
            ]
        )

但它实际上是用这些调用的:

Mockery_3_App_Contracts_IUserRepository->saveUser(Array, '1', '0')

所以不匹配。您不必将参数的名称放在那里，而是将它们的值放在那里。如果您需要通配符，请尝试 \Mockery::any()
