自动答题之 Selenium测试直接运行在浏览器中，就像真正的用户在操作一样。

2022-07-06 09:33:00 【心蓝168】

前几天接到的小单子，某些人员为了应付单位的硬性要求，每天必须在网上学习多少道题，每天必须在网上练习多少道题，所以想找人开发一个自动答题系统。上图为《某练兵比武在线学习》的自动答题演示。

怀着好奇的心里，在网上找找自动答题软件的实现方法，本想着使用IFrame，嵌入答题网页，使用jquery对网页进行操作，但后来发现打开答题窗口时，网页使用了target=_top，所以该方法又走不通了，只有接着百度溜达溜达，大概花了2小时左右，自动化测试工具，即：Selenium，可以直接通过浏览器进行操作。

这也是这几天和同事一起讨论自动系统巡检，检测系统的运行状态，这过程中，发现同事写的Demo也是自动，看到浏览器上东西不用鼠标操作，就能动起来，实在好玩。

"Selenium测试直接运行在浏览器中，就像真正的用户在操作一样"

官方网站为：http://www.selenium.org.cn/

具体的C#实现过程如下：

this.OutAnswerLog(string.Format("第 {0} 题等待：{1} 秒", (this.CountNumDay + 1).ToString().PadLeft(3, ' '), 0));

List<IWebElement> tabGroupList = DriverObj.FindElements(By.ClassName("question_tab_cui")).ToList();
if (tabGroupList.Count == 0)
{
return;
}
this.LearnCount = (new Random()).Next(31, 41);
List<IWebElement> tabItemsList = tabGroupList[0].FindElements(By.TagName("LI")).ToList();
foreach (IWebElement tabItem in tabItemsList)
{
//获取题类
