SeleniumBasic支持6种浏览器，每种浏览器的启动之前需要创建“选项”和“服务”。选项主要用于对浏览器的行为进行预设，而服务用于对驱动文件进行预设。

如果以Edge浏览器为例，那么需要创建EdgeOptions和EdgeDriverService。

这些浏览器的可用属性和方法，参考如下的XML文件。

<SeleniumBasic>
    <Chrome>
        <ChromeOptions AcceptInsecureCertificates="" BinaryLocation="C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" BrowserName="" BrowserVersion="" DebuggerAddress="" PlatformName="">

接下来讲述一下每种浏览器的Selenium环境构建方法。

最后讲一下在SeleniumBasic中的代码实现。

代码分析：利用API函数算出屏幕的宽度和高度，然后把5个浏览器的窗口大小和位置进行对齐排列。最后在循环中把每个浏览器退出。
