laravel - 测试一个方法是否被调用

Question

我正在尝试找出如何正确测试函数是否被调用。

此函数 busqueda 是在 Controller AnuncioController 中定义的，所以我希望它在用户单击发布到 anuncios/busqueda 的搜索按钮时被调用.

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 mock？

错误信息:

Routes.php 片段:

Route::post('anuncios/busqueda', [

AnuncioController.php 片段:

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

您创建了模拟对象 $mock_buscador 而没有实际使用它。您似乎希望 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 Controller 实例替换为 $mock_buscador 模拟对象。
