Selenium 简单使用

 Selenium功能  ：模拟人工操作，自动测试web。还可以执行js，编程简单，功能强大。 

 最近比较空闲，无聊记录下，以备遗忘.

 

使用

首先Nuget到项目

首先自定义个帮助类以便使用

 <code>

public enum BrowserType
{
IE,
Firefox,
Chrome,
Safari,
PhantomJS
} 

 </code>

 

public static class SeleniumHelper
{

public static IWebDriver GetWebDriver(BrowserType browser)
{
IWebDriver webDriver;
switch (browser)
{

case BrowserType.Chrome:
webDriver = new ChromeDriver();
break;
case BrowserType.Firefox:
webDriver = new FirefoxDriver();
break;
default:
webDriver = new ChromeDriver();
break;
}
return webDriver;
}

public static object ExecuteScript(this IWebDriver webDriver, string script, params object[] args)
{
if (webDriver == null)
throw new ArgumentNullException(nameof(webDriver));

IJavaScriptExecutor jsExecutor = webDriver as IJavaScriptExecutor;

Debug.Assert(jsExecutor != null, "jsExecutor != null");
return jsExecutor.ExecuteScript(script, args);
}
public static object ExecuteAsyncScript(this IWebDriver webDriver, string script, params object[] args)
{
if (webDriver == null)
throw new ArgumentNullException(nameof(webDriver));

IJavaScriptExecutor jsExecutor = webDriver as IJavaScriptExecutor;

Debug.Assert(jsExecutor != null, "jsExecutor != null");
return jsExecutor.ExecuteAsyncScript(script, args);
}

}

 

测试   

public void TestSelenium()
{
IWebDriver webDriver = SeleniumHelper.GetWebDriver(BrowserType.Chrome);

webDriver.Navigate().GoToUrl("https://www.baidu.com/");

for (int i = 0; i < 10000; i++)
{
webDriver.FindElement(By.Id("kw")).SendKeys(i.ToString());
webDriver.FindElement(By.Id("su")).Click();
Thread.Sleep(2000);
}
webDriver.FindElement(By.Id("kw")).SendKeys("江苏");
webDriver.FindElement(By.Id("su")).Click();
webDriver.ExecuteScript("alert('执行js')");
Thread.Sleep(2000);
webDriver.Quit();
}
