在c#中使用selenium选择选项项

本文关键字：选择 选项 selenium | 更新日期: 2023-09-27 18:04:06

我今天刚刚开始使用selenium编写一些UI测试。使用起来似乎很简单，而且取得了一些不错的进展。

我有一个使用最新测试版的kendoui的页面。他们有一个多选控件，我正在测试。

控件的输出html看起来像

<div class="k-widget k-multiselect k-header" style="">
  <div class="k-multiselect-wrap floatWrap">
    <ul role="listbox" unselectable="on" class="k-reset" id="StoreIds_taglist"></ul>
    <input class="k-input k-readonly" style="width: 119px;" accesskey="" role="listbox" aria-expanded="false" tabindex="0" aria-owns="StoreIds_taglist StoreIds_listbox" aria-disabled="false" aria-busy="false"><span class="k-loading" style="display: none;"></span></div>
    <select data-val="true" data-val-required="Please select at least 1 store" id="StoreIds" multiple="multiple" name="StoreIds" data-role="multiselect" style="display: none;" aria-disabled="false">
      <option value="d0f36ef4-28be-4d16-a2e8-37030004174a">stoe jo blogs</option>
      <option value="0f0afaec-797a-4b70-8599-ffb4176d7933">Store 3</option>
      <option value="11774315-a0e0-4686-8c70-b882a8f75ab4">store 5</option>
      <option value="28f32bc1-17de-4c73-8bed-b0abd7f5bd81">store 6</option>
      <option value="daf9927c-26a2-4395-ba6d-800d5af85ca7">store4</option>
      <option value="86bd876f-3312-4d1f-96ce-640e0dbf46df">z</option>
      <option value="7da8dfe0-f395-4dc3-9aed-1ce44ac280c0">zxzxc</option>
  </select>
  <span style="font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 14px; font-style: normal; font-weight: normal; letter-spacing: normal; text-transform: none; line-height: 18.328125px; position: absolute; visibility: hidden;">Select stores...    
  </span>
</div>

我正在尝试写一个selenium测试从选择列表中选择一个索引。

目前我有

   IWebElement sTag = driver.FindElement(By.Id("StoreIds"));
   SelectElement selectTag = new SelectElement(sTag);
   var availableOptions = selectTag.Options;

availbleOptions有7个条目，但是文本总是空的。基本上我正在尝试从列表中选择一个项目。

I try without luck

  foreach (IWebElement item in availableOptions)
        {
            item.Click();
            Console.WriteLine(item.Text);
        }

我得到一个错误

不能点击选项元素。(UnexpectedJavaScriptError)

我需要做什么来启用选择项目?

完整的测试示例

 [Test]
    public void TestMultiSelect()
    {
        driver.Navigate().GoToUrl("C:/temp/HTMLPage1.html");
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5));
        wait.Until((d) => { return d.Title.StartsWith("Test"); });
        var stores = driver.FindElement(By.Id("required"));
        IWebElement sTag = driver.FindElement(By.Id("required"));
        SelectElement selectTag = new SelectElement(sTag);
        var availableOptions = selectTag.Options;
        foreach (IWebElement item in availableOptions)
        {
            item.Click();
            Console.WriteLine(item.Text);
        }
    }

在c#中使用selenium选择选项项

你应该使用IJavaScriptExecutor来解决这个问题

//js.ExecuteScript(String.Format("$('#{0}').data('kendoMultiSelect').value({1});", "tagname", Value))
