Question

使用Firefox IDE时，并不是所有内容都可以翻译。我特别遇到以下问题：

ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=main | ]]

我可以像其他任何按钮一样点击窗口吗？我的问题是，由于跳过此步骤，自动化测试无法单击它下面的btnToDo元素。我想知道点击窗口是否是单击此特定实例中按钮的先决条件。

driver.findElement(By.id("btnLogin")).click();
// ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=main | ]]
driver.findElement(By.id("btnToDo")).click();

堆栈追踪：

我的错误表明该按钮不存在但显然确实存在。点击“btnLogin”后，我将进入新页面。在这里，似乎测试无法找到新的“btnToDo”。

看起来点击btnLogin，新窗口按照提供的录制代码填充。所以在这里我们需要切换到新窗口以与新窗口中的元素进行交互。因此，Selenium IDE中记录的切换窗口不会转换为WebDriver。

在webDriver中有概念getWindowHandles，它提供给它打开的所有Web浏览器。因此，首先收集这些句柄并迭代到打开的新句柄，然后切换到该句柄。完成该窗口中的工作后，如果需要，您需要切换回第一个窗口以在第一个窗口中交互元素。
