关于phpunit：无法进行断言，因为异常会导致我在Laravel中的测试崩溃

Can't make assertions because exceptions are crashing my test in Laravel

我想在尝试向API发送无效数据时测试响应。

/** @test */
public function request_schedule_with_invalid_bdate()
{
$response = $this->json('GET', '/api/schedule', [
'bdate' => 'thisaintadate',
]);

$response->assertStatus(422);
}

根据文档，它应返回422

If the validation rules pass, your code will keep executing normally; however, if validation fails, an exception will be thrown and the proper error response will automatically be sent back to the user. In the case of a traditional HTTP request, a redirect response will be generated, while a JSON response will be sent for AJAX requests.

也，

When using the validate method during an AJAX request, Laravel ... generates a JSON response containing all of the validation errors. This JSON response will be sent with a 422 HTTP status code.

听起来Laravel会自动处理抛出的异常并继续发送响应。

但是，在PHPUnit中运行它只会导致错误。

There was 1 error:

1) Tests\Feature\ScheduleTest::request_schedule_with_invalid_bdate
Illuminate\Validation\ValidationException: The given data was invalid.

我读了这个问题但是使用$this->expectException(...);会使测试通过但不会运行我的断言。如果我断言状态是422以外的其他东西，它仍然会通过。

我的控制器有这个：

public function show(Request $request)
{
$attributes = $request->validate([
'bdate' => 'required|date'
]);

return ['data' =>"It's valid."]
}

这是我的ExceptionHandler类(根据Martin H.的要求)这就是开箱即用的东西。我还没有触及过这门课程。

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

class Handler extends ExceptionHandler
{
/**
* A list of the exception types that are not reported.
*
* @var array
*/
protected $dontReport = [
//
];

/**
* A list of the inputs that are never flashed for validation exceptions.
*
* @var array
*/
protected $dontFlash = [
'password',
'password_confirmation',
];

/**
* Report or log an exception.
*
* @param \Exception $exception
* @return void

public function report(Exception $exception)
{
parent::report($exception);
}

/**

* @param \Exception $exception

*/
public function render($request, Exception $exception)
{
return parent::render($request, $exception);
}
}

我已确认以下内容：

Laravel Framework 5.7.21(php artisan --version输出)
它根据堆栈跟踪运行适当的代码/控制器：

... /供应商/ laravel /框架/ src目录/照亮/确认/ Validator.php：315
... /供应商/ laravel /框架/ SRC /照亮/验证/ Factory.php：136
... /供应商/ laravel /框架/ src目录/照亮/基金/供应商/ FoundationServiceProvider.php：53
... /供应商/ laravel /框架/ src目录/照亮/支持/特征/ Macroable.php：108
... /应用/ HTTP /控制器/ MyController.php：35

我错过了什么？
