selenium - Firefox WebDriver 挂起等待页面加载

Question

有时在我使用 Selenium 2.41 完成并使用 Firefox 28 进行的测试中，执行挂起等待页面加载。

这是等待条件:

int time = 30;    
WebDriverWait wait = new WebDriverWait(webDriver, time);
ExpectedCondition<Boolean> pageLoadCondition = new ExpectedCondition<Boolean>() {
   public Boolean apply(WebDriver driver) {
      return ((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete");
    }
};
wait.until(pageLoadCondition);

应该在 30 秒后此方法将抛出 TimeoutException，但事实并非如此，有时会永远挂起。
这是在这些情况下产生的堆栈跟踪:

我已经为 Firefox 配置文件设置了此首选项，但它仍然无法正常工作:

ffProfile = new FirefoxProfile();
ffProfile.setPreference("webdriver.load.strategy", "unstable");

也有这个属性设置:

webDriver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
webDriver.manage().timeouts().setScriptTimeout(30, TimeUnit.SECONDS);

您可能想尝试 Firefox 27.01。我升级到 Firefox 28.0，它似乎破坏了我使用 watir-webdriver 进行的一些测试。我回到 27.01 并再次运行测试(如果你回去下载整个安装包作为安装程序，似乎不允许你关闭自动更新，所以它会自动更新到 28.0)。

失败是使用悬停和 find_element。
