测试具有模型作为依赖项的 laravel 存储库

Question

问题是我无法测试一个功能，因为它涉及到同一存储库的其他功能。

1. 我是否需要将一个函数与同一存储库中的其他函数隔离测试，或者一个函数可以访问同一存储库中的其他函数是正常的？
2. 如果函数需要与其他函数隔离测试，该怎么做，因为我不明白如何模拟我正在工作的存储库。我了解如何模拟依赖项，但如何模拟同一存储库中的其他功能？
3. 我是否在测试中的 setUp 方法中正确地模拟了模型？

代码：

真实世界的绑定和存储库：

// Bind User repository interface
$app->bind('MyApp\Repositories\User\UserInterface', function () {
    return new EloquentUser(new User);
});

EloquentUser.php：

public function __construct(Model $user)
{
    $this->user = $user;
}

public function findById($id)
{
    return $this->user->find($id);
}

public function replace($data)
{
    $user = $this->findById($data['user']['id']);

    // If user not exists, create new one with defined values.
    if ( ! $user) {
        return $this->create($data);
    } else {
        return $this->update($data);
    }
}

public function create($data)
{
    $user = $this->user->create($data['user']);

    if ($user) {

        return $this->createProfile($user, $data['profile']);

    } else {

        return false;
    }
}

private function createProfile($user, $profile)
{
    return $user->profile()->create($profile);
}

public function update($user, $data)
{
    foreach ($data['user'] as $key => $value) {
        $user->{$key} = $value;
    }

    if (isset($data['profile']) && count($data['profile']) > 0) {

        foreach ($data['profile'] as $key => $value) {
            $user->profile->$key = $value;
        }
    }

    return ($user->push()) ? $user : false;
}

EloquentUserTest.php

public function setUp()
{
    parent::setUp();
    $this->user = Mockery::mock('Illuminate\Database\Eloquent\Model', 'MyApp\Models\User\User');
    App::instance('MyApp\Models\User\User', $this->user);
    $this->repository = new EloquentUser($this->user);
}

public function testReplaceCallsCreateMethod()
{
    $data = [
        'user' => [
            'id' => 1,
            'email' => 'test@test.com',
        ],
        'profile' => [
            'name' => 'John Doe',
            'image' => 'abcdef.png',
        ],
    ];

    // Mock the "find" call that is made in findById()
    $this->user->shouldReceive('find')->once()->andReturn(false);

    // Mock the "create" call that is made in create() method
    $this->user->shouldReceive('create')->once()->andReturn(true);

    // Run replace method that i want to test
    $result = $this->repository->replace($data);

    $this->assertInstanceOf('Illuminate\Database\Eloquent\Model', $result, 'Should be an instance of Illuminate\Database\Eloquent\Model');
}

运行此测试时，我得到：

Fatal error: Call to a member function profile() on a non-object in C:\Htdocs\at.univemba.com\uv2\app\logic\Univemba\Repositories\User\EloquentUser.php on line 107

所以这意味着Test试图在EloquentUser.php中触摸函数：

private function createProfile($user, $profile)
{
    return $user->profile()->create($profile);
}

我需要模拟 createProfile 吗？因为 profile() 找不到。如果我需要这样做，我该怎么做，因为这个函数在我正在测试的同一个存储库中？

Answer 1

问题解决了。 只需要再创建一个 Model 实例并将其传递给 mocked 方法。

我的工作设置方法：

public function setUp()
{
    parent::setUp();

    $this->user = Mockery::mock('MyApp\Models\User\User');

    App::instance('MyApp\Models\User\User', $this->user);

    $this->repository = new EloquentUser($this->user);
}

工作测试方法：

public function testReplaceCallsCreateMethod()
{
    $data = [
        'user' => [
            'id' => 1,
            'email' => 'test@test.com',
            'password' => 'plain',
        ],
        'profile' => [
            'name' => 'John Doe',
            'image' => 'abcdef.png',
        ],
    ];

    // Mock Model's find method
    $this->user->shouldReceive('find')->once()->andReturn(false);

    // Create new Model instance
    $mockedUser = Mockery::mock('MyApp\Models\User\User');

    // Mock Models profile->create and pass Model as a result of a function
    $mockedUser->shouldReceive('profile->create')->with($data['profile'])->andReturn($mockedUser);

    // Pass second instance Model as a result
    $this->user->shouldReceive('create')->once()->andReturn($mockedUser);

    // Now all $user->profile is properly mocked and will return correct data
    $result = $this->repository->replace($data);

    $this->assertInstanceOf('Illuminate\Database\Eloquent\Model', $result, 'Should be an instance of Illuminate\Database\Eloquent\Model');
}
