IE的Selenium WebDriver错误

Question

我正在尝试使用seleniumwebdriver，junit和ant
build自动化测试用例。自从早上以来，我收到了一些奇怪的错误。一个测试用例包含按钮单击命令。该测试在Chrome和FF上运行成功，但在IE上未成功。此前，至少有人说无法找到元素X，但是有人说服务器未提供任何信息。

Answer 1

在触发点击事件之前插入以下代码块

for (int second = 0;; second++) {
    if (second >= 60) return "Page load failed";
    try {
        if (session().isTextPresent("Logoff")) 
            break;
    } 
    catch (Exception e) {}
    Thread.sleep(1000);
}

就我而言，我拥有测试用例的超类，这就是为什么我可以做的原因

session().somecommand

但是，您可以将我的解决方案转化为您的解决方案。
