在我通过设计登录后，我点击带有附加 javascript 的按钮，这使得一些 HTML 可见。
<button id="btn_simple_search"
class="btn btn-primary btn-md well_button"
data-toggle="button"
>
Search
</button>
调用函数
$("#btn_simple_search").click(function(){
$("#simple_search").toggle(500);
});
我希望水豚测试等到这个功能完成（我不知道 - 比如一些回调或其他东西）而不是sleep 0.6在我点击其他按钮或从新显示的 HTML 块中选择一些选项之前进行。我使用 Minitest 作为测试框架。怎么做？
上面的 javascript 直接嵌入在页面上。
伙计们,昨天我升级到High Sierra.
之后 - 我无法启动我的项目导致此错误:
2017-09-27 16:52:48 +0300: Rack app error handling request { GET /unauthenticated }
