如何模拟 laravel 助手 function 请求

Question

你如何模拟 request() 助手 function？

例如，如果我有一个拨打电话的 function

$name = request()->input('name')

如何模拟该调用，我尝试了以下方法，但我收到一个错误，它从未被调用

$requestMock = $this->mock(Request::class);
$requestMock->shouldReceive('input')->once()->andReturn($name);

If you look at the request() helper ( https://github.com/laravel/framework/blob/05da44d6823c2923597519ac10151f5827a24f80/src/Illuminate/Foundation/helpers.php#L602 ) it's retrieving an instance of the Request class from the Container. 设置模拟请求 class 并添加您需要将其绑定到容器的期望后：

$this->app->instance('request', $mock);
