我正在尝试为我的应用程序自动化我的测试用例。我已经添加了代码和屏幕截图供您参考。 应用程序中只有一个添加按钮，因此我很容易为add编写一个事件。但是如屏幕所示，存在大量删除按钮。因此，我很难自动化动态删除按钮。现在我正在尝试编写删除所有记录的代码。但是Id和类都没有在html代码中工作。请写。请帮助。
屏幕截图位于http://imgur.com/zgmgKq3 btn inverse和icon trash是我找到的类标识符

答案 0 :(得分：0)
您似乎需要点击此表格单元格中的<a>元素：
<td>
<a class="btn btn-inverse">
<i class="icon-trash"></i>
</a>
</td>
这个元素有什么独特之处？如果您知道任何带有btn-inverse类的按钮将始终是删除按钮，请查找该按钮。此xPath定位器正在查找其类属性值包含<a>的任何btn-inverse元素。
List<WebElement> del_elements=driver.findElements(By.xPath("//a[contains(@class,'btn-inverse')]"));
如果这不起作用，您很可能想要考虑<i class="icon-trash">孩子。此xPath定位器将搜索具有子属<a>元素的<i>元素，其中类属性值为icon-trash
List<WebElement> del_elements=driver.findElements(By.xPath("//a[i/@class='icon-trash']"));
另请注意，这些元素都不具有id属性，因此下面代码中的linkid字符串将始终为空：
for(WebElement mylink :del_elements)
{
mylink.Click();
// do anything else here to handle deleting the entry
String linkid= mylink.getAttribute("id");
Thread.sleep(5000);
System.out.println("Deleting element:" + linkid);
}
