测试一个方法是否被调用

Question

我正在尝试弄清楚如何正确测试函数是否被调用。

此函数 busqueda 是在控制器 AnuncioController 中定义的，因此我希望它在用户单击搜索按钮时被调用发布到 anuncios/busqueda.

就我而言，这可以通过模拟来完成。这是我试过的：

use \App\Http\Controllers;
class ExampleTest extends TestCase
{

   public function testBuscador()
   {
    $mock_buscador = Mockery::mock(\App\Http\Controllers\AnuncioController::class);
    $mock_buscador->shouldReceive('busqueda')->once()->andReturn(null);
    $this->visit('/')->submitForm('Buscar')->seePageIs('anuncios/busqueda');
   }

}

但是assert总是失败，我是不是用错了mocks？

错误消息：

PHPUnit 4.8.21 by Sebastian Bergmann and contributors.

public function busqueda(Request $request)
{...}

Answer 1

尝试使用控制器的完整路径。

use \App\Http\Controllers;
class ExampleTest extends TestCase
{

   public function testSearch()
   {
        $mock_search = Mockery::mock(\App\Http\Controllers\AnuncioController::class);
        // or if you aren't using php 5
        // $mock_search = Mockery::mock('\App\Http\Controllers\AnuncioController');
        $mock_search->shouldReceive('busqueda')->once()->andReturn(null); 
        $this->visit('/')->submitForm('Buscar')->seePageIs('anuncios/busqueda');

   }
}

我会为你的控制器使用 Mockery。我会更多地将它用于 Facades。我会重写测试以测试您想在页面上看到的内容。

use \App\Http\Controllers;
class ExampleTest extends TestCase
{

   public function testSearch()
   {
        $this->visit('/')
          ->type('expected', 'search')
          ->submitForm('Buscar')
          ->seePageIs('anuncios/busqueda')->
          ->see('expected results');

   }
}

您创建了模拟对象 $mock_buscador 而没有实际使用它。似乎您希望 App\Http\Controllers\AnuncioController 的任何实例都被模拟替换，但事实并非如此。您需要将使用的控制器实例替换为 $mock_buscador 模拟对象。
