使用 Laravel 和 Mockery 进行单元测试 REST 更新答案

【问题描述】：

我似乎无法弄清楚如何对控制器的更新进行单元测试。我收到以下错误：

method update() from Mockery_0_App.... Should be called exactly 1 times but called 0 times.

删除更新中的 if 语句后（检查是否存在过敏），我在添加唯一验证规则的 id 的行中收到以下错误：

Trying to get property of on object

我的代码：

控制器：

class AllergyController extends \App\Controllers\BaseController
{
    public function __construct(IAllergyRepository $allergy){
        $this->allergy = $allergy;
    }

    ...other methods (index,show,destroy) ...

    public function update($id)
    {
        $allergy = $this->allergy->find($id);

        //if ($allergy != null) {
            //define validation rules
            $rules = array(
                'name' => Config::get('Patient::validation.allergy.edit.name') . $allergy->name
            );

            //execute validation rules
            $validator = Validator::make(Input::all(), $rules);
            $validator->setAttributeNames(Config::get('Patient::validation.allergy.messages'));

            if ($validator->fails()) {
                return Response::json(array('status' => false, 'data' => $validator->messages()));
            } else {
                $allergy = $this->allergy->update($allergy, Input::all());

                if ($allergy) {
                    return Response::json(array('status' => true, 'data' => $allergy));
                } else {
                    $messages = new \Illuminate\Support\MessageBag;
                    $messages->add('error', 'Create failed! Please contact the site administrator or try again!');

                    return Response::json(array('status' => false, 'data' => $messages));
                }
            }
        //}
        $messages = new \Illuminate\Support\MessageBag;
        $messages->add('error', 'Cannot update the allergy!');

        return Response::json(array('status' => false, 'data' => $messages));
    }

}

测试用例：类 AllergyControllerTest 扩展了 TestCase {

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

    $this->allergy = $this->mock('App\Modules\Patient\Repositories\IAllergyRepository');
}

public function mock($class)
{
    $mock = Mockery::mock($class);

    $this->app->instance($class, $mock);

    return $mock;
}

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

public function testIndex()
{
    $this->allergy->shouldReceive('all')->once();

    $this->call('GET', 'api/allergy');

    $this->assertResponseOk();
}

...Other tests for Index and Show ...

public function testUpdate()
{
    $validator = Mockery::mock('stdClass');
    Validator::swap($validator);

    $input = array('name' => 'bar');

    $this->allergy->shouldReceive('find')->with(1)->once();
    $validator->shouldReceive('make')->once()->andReturn($validator);
    $validator->shouldReceive('setAttributeNames')->once();
    $validator->shouldReceive('fails')->once()->andReturn(false);;
    $this->allergy->shouldReceive('update')->once();

    $this->call('PUT', 'api/allergy/1', $input);

    $this->assertResponseOk();
}

}

配置验证规则文件：

return array(
    'allergy' => array(
        'add' => array(
            'name' => 'required|unique:Allergy'
        ),
        'edit' => array(
            'name' => 'required|unique:Allergy,name,'
        ),
        'messages' => array(
            'name' => 'Name'
        )
    )
);

有没有办法真正模拟验证规则中提供的值？或者解决这个问题的最佳方法是什么？

【解决方案1】：

我将我的代码更改为这个，现在它可以工作了！ :)

$validator = Mockery::mock('stdClass');
Validator::swap($validator);

$allergyObj = Mockery::mock('stdClass');
$allergyObj->name = 1;

$input = array('name' => 'bar');

$this->allergyRepo->shouldReceive('find')->with(1)->once()->andReturn($allergyObj);
$validator->shouldReceive('make')->once()->andReturn($validator);
$validator->shouldReceive('setAttributeNames')->once();
$validator->shouldReceive('fails')->once()->andReturn(false);;
$this->allergyRepo->shouldReceive('update')->once();

$this->call('PUT', 'api/allergy/1', $input);

$this->assertResponseOk();
