我的MojolicIoUs控制器包含：

sub submit_new {
    my $self = shift;

    my $new = $self->db->resultset('Item')->new( {
        title       => $self->param('title'),description => $self->param('description'),} );
    $new->insert;

    # show the newly submitted item
    my $id = $new->id;
    $self->redirect_to("/items/$id");
}

该控制器的测试脚本包含：

use Test::More;
use Test::Mojo;

my $t = Test::Mojo->new('MyApp');

my $tx = $t->ua->build_form_tx('/items/new/submit' => $data);
$tx->req->method('POST');
$t->tx( $t->ua->start($tx) )
  ->status_is(302);

我的问题是它以302状态停止.如何继续重定向,以便我可以验证生成的项目页面？
