PHPUnit / Laravel 5.2中无法访问的字段“isTeam0”

Question

我有一个复选框：

<input class="switch" data-on-text="Si" data-off-text="No" id="isTeam0" 
checked="checked" name="isTeam" type="checkbox" value="1">

当我尝试使用以下功能进行功能测试时

$this->visit('/tournaments/' . $tournament->id . '/edit')
        ->type('1', 'isTeam0')
        ->press('save0');

我收到此错误消息：

1) TournamentTest::it_create_tournament_category_conf

InvalidArgumentException：无法访问的字段“isTeam0”

我不知道该怎么做才能让它发挥作用......

任何想法???
