Selenium则是一个利用http协议，来实现js和其他语言之间的通信，他强大的地方是js部分。
ide/main/src/content/selenium-runner.js
// overide _executeCurrentCommand so we can collect stats of the commands executed
_executeCurrentCommand : function() {
/**
* Execute the current command.
*
* @return a function which will be used to determine when
* execution can continue, or null if we can continue immediately
*/
var command = this.currentCommand;
LOG.info("Executing: |" + command.command + " | " + command.target + " | " + command.value + " |");
var handler = this.commandFactory.getCommandHandler(command.command);
if (handler == null) {
throw new SeleniumError("Unknown command: '" + command.command + "'");
}
command.target = selenium.preprocessParameter(command.target);
command.value = selenium.preprocessParameter(command.value);
LOG.debug("Command found, going to execute " + command.command);
updateStats(command.command);
this.result = handler.execute(selenium, command);
this.waitForCondition = this.result.terminationCondition;
},
selenium-api,CommandHandlerFactory是Api核心，在selenium-api.js,selenium-commandhandlers.js文件中实现。
