Question

我正在对道路的不同响应进行单元测试（通常情况下，道路受身份验证保护）。我设法模拟了用户身份验证。但是，由于存在数据库连接错误，因此无法模拟调用数据库的模型的方法。

您知道如何在不调用数据库的情况下模拟他的方法吗？

这就是我所做的。

控制器

    class XYZController extends Controller{

    ...
        public function index(Request $request){
            $user   = Auth::user();
            $person = $user->person()->first(); // how mock the method person - from the I have the database error.
            $phone  = $user->phone()->first();// how mock the method phone
            $prefix = $phone->country()->first()->code; // how mock the method country
            $email  = $user->email;
            $pays   = Pays::where('xyz', false)->get(); // how mock the method person
    ...
            return view('xyz',[
                ...
            ]);
        }
    ...
    }

测试

    class XYZTest extends TestCase{

        public function testRouteMain(){
          $user = factory(User::class)->make();
          $person = factory(Person::class)->make();

          $this->withoutMiddleware();
          $this->be($user);

          $mockUser = Mockery::mock(User::class);

          $mockUser->shouldReceive('person')->andReturn(collect());
          $mockUser->shouldReceive('first')->andReturn($person);
          $this->app->instance(User::class, $mockUser);
          $reponse = $this->get(route('xyz_route'));

          $this->assertEquals(Response::HTTP_OK, $reponse->>getStatusCode(), 'The status code expected is '.Response::HTTP_OK);// I put the doubles ">>" on purpose , it's to avoid having the blockquote
       }
    }

Answer 1

尝试一下：

$mockUser = Mockery::mock(User::class);
$this->app->instance(User::class, $mockUser);
          ^^^^^^^^^^

此外，如果我没记错的话：

$mockUser->shouldReceive('person')->andReturn(collect());
$mockUser->shouldReceive('first')->andReturn($person);

为每个调用的方法重复。

如何模拟用PhpUnit查看另一个模型的一个或多个实例的模型方法？
