If you are using Selenium 2 aka Webdriver I d do it like this:
如果您使用的是 Selenium 2 又名 Webdriver，我会这样做：
Select select = new Select(driver.findElemetn(/*Way to your drop down*/));
select.selectByValue("your value")
//or
select.selectByVisibleText("your Test");
//alternativly you can do something like this
List<WebElement> options = select.getOptions();
//find your desired option
select.selectByVisibleText(option.getText());
Hope that helps.
希望有帮助。

If you use IE8 or greater, press F12and use the Developer Tools there. Particularly helpful should be the cursor icon, i.e. Select Element By Click which will allow you to select any element and see all the attributes assigned to it.
如果您使用 IE8 或更高版本，请按F12并使用那里的开发人员工具。特别有用的是光标图标，即通过单击选择元素，它允许您选择任何元素并查看分配给它的所有属性。
If you use Firefox 11, there is a similar tool under Web Developer menu. Or use the Firebug addon which is stronger, but more complex.
如果您使用 Firefox 11，Web Developer 菜单下有一个类似的工具。或者使用更强大但更复杂的 Firebug 插件。
But!The main problem you'll have that the id will change from time to time. It seems to be generated automatically. That means you'll have to use some other way to select the element. You can use for example selenium.select("id=skuOptionSIZE*", "label=8");, or find it by XPathor css selector.
但！您将遇到的主要问题是 ID 会不时更改。好像是自动生成的。这意味着您必须使用其他方式来选择元素。例如selenium.select("id=skuOptionSIZE*", "label=8");，您可以使用，或者通过XPath或css 选择器找到它。

If you download the Webdriver Support dll then you can use the following
如果您下载 Webdriver Support dll，则可以使用以下内容
SelectElement select = new SelectElement(element);
select.SelectByIndex(8); //Where the number 8 is the base 0 index of the options
So if you have 10 options (0-9) SelectByIndex(8)will return the ninth option.
所以如果你有 10 个选项 (0-9)SelectByIndex(8)将返回第九个选项。
