Desired Capabilities是由客户端发送给Appium服务器端的用来告诉服务器去启动哪种我们想要的会话的一套键值对集合。当中也有一些键值对是用来在自动化的过程中修改服务器端的行为方式的。比如，我们可以把键为platformName的capability的值设置成iOS来告诉服务器我们想要开启的是一个iOS的会话，而非Anddroid的会话。或者我们可以把键为safariAllowPopups 的capability的值设置成true来确保在Safari自动化会话的过程中，我们可以使用JavaScript来弹出一个新窗口。要查看Appium支持的完整的capabilities列表，请查看capabilities doc或以下文档。
请注意以下列表中高亮的项，这些都是必填的项目。当中有以下几点需要注意的：
