selenium WebDriver 浏览器发动机

选择三种做为介绍：

一、Firefox Driver

引入方式：

WebDriver driver = new FirefoxDriver();

二、InternetExplorer Driver

引入方式1:

WebDriver driver = new InternetExplorerDriver();

对于报错，采用方式2：

?

DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer(); 
		ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true); 
		driver = new InternetExplorerDriver(ieCapabilities);

?

三、Chrome Driver?

引入方式1：

WebDriver driver = new ChromeDriver()

?

对于报错，采用方式2：

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
		capabilities.setCapability("chrome.binary", "/opt/google/chrome/chromedriver");
		driver = new ChromeDriver(capabilities);

?

注：Firefox Driver速度较慢。对于https的页面，需要安装安全证书，要不然会找不到客户端cookie。
