Java-Selenium sendKeys()对于Chrome,Firefox和Safari的不同行为

以下是简单的代码段.

@FindBy(className = "element-to-press")
private WebElement elementToPress;

// some other code

Keys move = Keys.ARROW_DOWN;
gridContainer.sendKeys(move);

在Firefox中,一切正常.

在Chrome浏览器中,我收到“ org.openqa.selenium.WebDriverException：未知错误：无法聚焦元素”错误

Safari不响应sendKeys()

我也尝试使用另一种方法：

Keys move = Keys.ARROW_DOWN;
Actions actions = new Actions(driver);
actions.movetoElement(element).click(); // to focus on element
actions.sendKeys(move).perform();

此代码修复了Chrome浏览器“无法聚焦元素”错误,但浏览器仍无法对Keys.ARROW_DOWN / Keys.ARROW_UP / Keys.ARROW_LEFT / Keys.ARROW_RIGHT事件做出反应

Safari和Firefox也不会对sendKeys()做出反应.

我不知道发生了什么以及如何使我的代码在所有这些浏览器上运行.

环境：

> OS X 10.9.5
>最新版本的Chrome / Safari / Firefox
>硒版本2.44.0

UPD：

将Selenium更新到2.46版.

现在适用于Chrome和Firefox.

但是Safari仍然存在问题：org.openqa.selenium.remote.UnreachablebrowserException：无法启动新的会话.

UPD2：

我安装了Safari浏览器扩展程序.

解决方法:

如聊天中所讨论的,您想自动化2048

解决方法是我写了Javascript based on this发送Arrow KeyEvents,并且它在所有浏览器上都有效

您要做的就是发送箭头键,根本不需要单击元素[和查找元素,除非您创建一个基于值播放的算法]

你让我明白了以下内容将为3个浏览器玩200(50 x 4)种不同动作的游戏
