Selenium keys.chord 不释放控制键答案

【问题标题】：Selenium keys.chord does not release control keysSelenium keys.chord 不释放控制键
【发布时间】：2013-10-16 04:28:11
【问题描述】：

这段代码选择了两个文本框，因为似乎控制键没有释放。

findElement('#textbox-wrapper').click();
findElement('#textbox').sendKeys(Keys.chord(Keys.CONTROL, "A"))
findElement('#textbox2-wrapper').click();

如果我注释掉中间行，它会按顺序选择文本框，而在测试结束时按预期选择第二个。

如果我在 sendKeys 之后注释掉两次点击并在浏览器窗口上手动按 f，它会执行 Ctrl+F 查找，因此看起来 sendKeys 肯定没有释放 ctrl。

有趣的是，发送另一个键 findElement('#textbox').sendKeys("A") 似乎可以解决问题，因为在此之后单击或按 f 不再像按住 ctrl 一样。

selenium 文档似乎表明存在一个问题

Note: When the low-level webdriver key handlers see Keys.NULL, active modifier keys (CTRL/ALT/SHIFT/etc) release via a keyup event. Issue: http://code.google.com/p/webdriver/issues/detail?id=79

但是那个链接坏了……

Webdriver - java - how to release keys after performing an action

【解决方案1】：

如果有人碰巧遇到同样的问题，这是我的解决方案。我无法让 webdriver 释放控制键，所以我让机器人在每个 sendkey 之后释放任何按下的控制键。使用崇高文本生成，使用愉快。

有一种简洁的方法可以释放和弦控制键； see my answer.

【解决方案2】：

我刚刚想出了一个解决方法。

我不知道它是否会影响其他事情，但它对我来说很好。

driver.findElement(By.cssSelector("body")).sendKeys(Keys.ESCAPE);
