Laravel 扩展 TestResponse 类

我正在尝试添加自定义断言TestReponse https://laravel.com/api/5.5/Illuminate/Foundation/Testing/TestResponse.html类所以我可以做这样的事情：

$response = $this->json('POST', '/foo/bar');

$response->myCustomAssertion();

我尝试创建一个App\TestResponse扩展原始类，然后将其绑定到App\Provider\AppServiceProvider class.

public function register()
{
    $this->app->bind('Illuminate\Foundation\Testing\TestResponse', function ($app) {
        return new App\TestResponse();
    });
}

But $response->json()仍然返回原始的而不是我自己的实现。

我怎样才能延长TestResponse class?

如果你想要更细粒度的控制，你还可以扩展Illuminate\Foundation\Testing\TestResponse，就像你所做的那样，然后覆盖createTestResponse方法在你的TestCase类返回自定义响应类的实例：

// Laravel 8 and above
protected function createTestResponse($response)
{
    return tap(App\TestResponse::fromBaseResponse($response), function ($response) {
        $response->withExceptions(
            $this->app->bound(LoggedExceptionCollection::class)
                ? $this->app->make(LoggedExceptionCollection::class)
                : new LoggedExceptionCollection
        );
    });
}

// Before Laravel 8
protected function createTestResponse($response)
{
    return App\TestResponse::fromBaseResponse($response);
}
