【中文标题】这个模拟对象上不存在方法 - Laravel,Mockery【英文标题】:method does not exist on this mock object - Laravel , Mockery 【发布时间】:2015-03-01 01:41:48 【问题描述】:

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

我在运行测试时遇到此错误:

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,我的控制器调用存储库并返回 Eloquent 的响应。

我在 php 和 laravel 方面相对较新。几天前我已经开始学习测试,所以我很抱歉那个凌乱的代码。

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: 没有什么真正有趣的。

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);


我的雄辩实现: 也没有什么真正有趣的东西。

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 MealTypeRepositoryInterface:

interface MealTypeRepositoryInterface

public function all();

public function find($id);

public function create($input);

public function getValidator($input);

最后,我的控制器:

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,该应用程序有效,只是测试搞砸了。 有谁知道,为什么会这样?我看不出 TestCase 的方法 - testIndex 和 testStoreFails 之间的区别,为什么找到方法“all”而没有找到“getValidator”。 我将不胜感激任何建议。

【问题讨论】:

【参考方案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:

    您收到错误 BadMethodCallException: Method Mockery_0_MyClass::myMethod() does not exist on this mock object,并且 您的任何模拟都没有采用您的主题的任何方法,并且 正在自动加载您的类(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。所以 Test 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');
    

我现在已经忘记了 3 次了,每次都花一两个小时想知道到底是什么问题!

【参考方案2】:

我在控制器中找到了这个错误的来源。 叫错了

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

而不是正确的

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