php - 此模拟对象上不存在方法 - Laravel，Mockery

Question

我正在尝试测试一个简单的类。我正在学习本教程 ( http://code.tutsplus.com/tutorials/testing-laravel-controllers--net-31456 )。

我在运行测试时遇到这个错误:

Method Mockery_0_App_Interfaces_MealTypeRepositoryInterface::getValidator() does not exist on this mock object

我正在使用存储库结构。因此，我的 Controller 调用存储库并返回 Eloquent 的响应。

我是 php 和 laravel 的新手。而且我几天前就开始学习测试了，所以对于那些乱七八糟的代码我很抱歉。

我的测试用例:

class MealTypeControllerTest extends TestCase
{
public function setUp()
{
    parent::setUp();

    $this->mock = Mockery::mock('App\Interfaces\MealTypeRepositoryInterface');
    $this->app->instance('App\Interfaces\MealTypeRepositoryInterface' , $this->mock);
}
public function tearDown()
{
    Mockery::close();
}

public function testIndex()
{
    $this->mock
         ->shouldReceive('all')
         ->once()
         ->andReturn(['mealTypes' => (object)['id' => 1 , 'name' => 'jidlo']]);

    $this->call('GET' , 'mealType');

    $this->assertViewHas('mealTypes');
}

public function testStoreFails()
{
    $input = ['name' => 'x'];

    $this->mock
         ->shouldReceive('getValidator')
         ->once()
         ->andReturn(Mockery::mock(['fails' => true]));

    $this->mock
         ->shouldReceive('create')
         ->once()
         ->with($input);


    $this->call('POST' , 'mealType' , $input ); // this line throws the error

    $this->assertRedirectedToRoute('mealType.create');//->withErrors();

    $this->assertSessionHasErrors('name');
}

}

我的 EloquentMealTypeRepository:没什么特别有趣的。

class EloquentMealTypeRepository implements MealTypeRepositoryInterface
{
public function all()
{
    return MealType::all();
}

public function find($id)
{
    return MealType::find($id);
}

public function create($input)
{
    return MealType::create($input);
}

public function getValidator($input)
{
    return MealType::getValidator($input);
}
}

我 Eloquent 实现:也没什么特别有趣的。

class MealType extends Model
{
private $validator;

/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'meal_types';

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = ['name'];

/**
 * The attributes excluded from the model's JSON form.
 *
 * @var array
 */
protected $hidden = [];

public function meals()
{
    return $this->hasMany('Meal');
}

public static function getValidator($fields)
{
    return Validator::make($fields, ['name' => 'required|min:3'] );
}
}

我的 MealTypeRepository 接口(interface):

interface MealTypeRepositoryInterface
{
public function all();

public function find($id);

public function create($input);

public function getValidator($input);
}

最后，我的 Controller :

class MealTypeController extends Controller {
protected $mealType;

public function __construct(MealType $mealType)
{   
    $this->mealType = $mealType;
}


/**
 * Display a listing of the resource.
 *
 * @return Response
 */
public function index()
{
    $mealTypes = $this->mealType->all();
    return View::make('mealTypes.index')->with('mealTypes' ,$mealTypes);
}

/**
 * Show the form for creating a new resource.
 *
 * @return Response
 */
public function create()
{
    $mealType = new MealTypeEloquent;
    $action = 'MealTypeController@store';
    $method = 'POST';

    return View::make('mealTypes.create_edit', compact('mealType' , 'action' , 'method') );     
}

/**
 * Validator does not work properly in tests.
 * Store a newly created resource in storage.
 *
 * @return Response
 */
public function store(Request $request)
{
    $input = ['name' => $request->input('name')];

    $mealType = new $this->mealType;

    $v = $mealType->getValidator($input);

    if( $v->passes() )
    {
        $this->mealType->create($input);
        return Redirect::to('mealType');
    }
    else
    {
        $this->errors = $v;
        return Redirect::to('mealType/create')->withErrors($v);
    }
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function show($id)
{
    return View::make('mealTypes.show' , ['mealType' => $this->mealType->find($id)]);
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function edit($id)
{
    $mealType = $this->mealType->find($id);
    $action = 'MealTypeController@update';
    $method = 'PATCH';
    return View::make('mealTypes.create_edit')->with(compact('mealType' , 'action' , 'method'));
}

/**
 * Update the specified resource in storage.
 *
 * @param  int  $id
 * @return Response
 */
public function update($id)
{
    $mealType = $this->mealType->find($id);
    $mealType->name = \Input::get('name');
    $mealType->save();
    return redirect('mealType');
}

/**
 * Remove the specified resource from storage.
 *
 * @param  int  $id
 * @return Response
 */
public function destroy($id)
{
    $this->mealType->find($id)->delete();
    return redirect('mealType');
}

}

这应该就是一切。值得一提的是，该应用程序可以正常工作，只是测试搞砸了。有谁知道，为什么会这样？我看不出 TestCase 方法之间的区别 - testIndex 和 testStoreFails，为什么找到了方法“all”而没有找到“getValidator”。如果有任何建议，我将不胜感激。

Answer 1

也许是旁白，但与通过标题找到此问题的任何人直接相关:

如果:

1. 您收到错误 BadMethodCallException: Method Mockery_0_MyClass::myMethod() does not exist on this mock object，并且
2. 您的模拟都没有采用您主题的任何方法，并且
3. 您的类(class)正在自动加载，(例如使用 composer)

然后在制作模拟对象之前，您需要使用以下代码行强制加载该主题:

spl_autoload_call('MyNamespace\MyClass'); 

然后你可以模拟它:

$mock = \Mockery::mock('MyNamespace\MyClass');

在我的 PHPUnit 测试中，我经常将第一行放入 setUpBeforeClass() 静态函数中，因此它只被调用一次并且与添加/删除的测试隔离开来。所以测试类看起来像这样:

class MyClassTest extends PHPUnit_Framework_TestCase {
    public static function setUpBeforeClass() {
        parent::setUpBeforeClass();
        spl_autoload_call('Jodes\MyClass'); 
    }
    public function testIt(){
        $mock = \Mockery::mock('Jodes\MyClass');
    }
}

我已经忘记这件事三次了，每次都花一两个小时想知道到底是什么问题!
