nightwatch - 如何在引导菜单中查找链接文本

Question

我有以下bootstrap navBar

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">PRiSM</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#" id="menu-home">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item dropdown menu-applications-dropdown" >
        <a  class="nav-link dropdown-toggle menu-applications" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Applications</a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
          <a class="dropdown-item" href="#" id="menu-aol-dashboards">AOL Dashboards</a>
          <a class="dropdown-item" href="#" id="menu-pricing">Pricing</a>
          <div class="dropdown-divider"></div>
          <a class="dropdown-item" href="#" id="menu-prism">PRiSM</a>
        </div>
      </li>

    </ul>

  </div>
</nav>

我正在使用以下的守夜人测试来期待一些特定的菜单文本。

这是我的测试

browser
  .url('http://localhost:8082/#/main_menu')
  .waitForElementVisible('#app', 5000)
  .expect.element('a.menu-applications').text.to.equal('Applications');

我得到的结果是

Running:  default e2e tests


√ Element <#app> was visible after 46 milliseconds.
 × Expected element <a.menu-applications> text to equal: "Applications" expected "equal 'Applications'" but got: ""
