ddValidation.php

<?php

// Place this method somewhere in TestCase.php

protected function ddValidation(array $except = [])
{
    if ($this->originalExceptionHandler == null) {
        $this->originalExceptionHandler = app(ExceptionHandler::class);
    }

    $this->app->instance(ExceptionHandler::class, new class($this->originalExceptionHandler) implements ExceptionHandler {
        protected $originalHandler;

        public function __construct($originalHandler)
        {
            $this->originalHandler = $originalHandler;
        }

        public function report(Exception $e)
        {
            //
        }

        public function render($request, Exception $e)
        {
            if ($e instanceof ValidationException) {
                dd($e->errors());
            }

            throw $e;
        }

        public function renderForConsole($output, Exception $e)
        {
            (new ConsoleApplication)->renderException($e, $output);
        }
    });

    return $this;
}
