Question

我正在测试登录页面。在某些时候（读作间歇性），主页的加载需要无限的时间。在这种情况下，以下命令永远不会完成 -

driver.findElement(By.id("Login")).submit();

我知道隐含的＆amp;明确的等待。这些等待仅适用于findElement或DOM相关操作，但不适用于提交命令（（Ref：https://sqa.stackexchange.com/questions/2606/what-is-seleniums-default-timeout-for-page-loading）

调试日志跟踪 -

基本上，DefaultClientConnection没有收到200 OK＆amp;命令只是挂起。

在等待特定时间后，如果浏览器没有响应提交命令，请寻找关闭浏览器的解决方案。

Answer 1

我猜id“登录”是一个表单。

您是否可以选择表单的提交按钮（假设存在一个）并在按钮上调用.click（），而不是在表单上调用.submit（）？

然后你应该能够使用隐式或显式等待。

编辑：

提交表单后，您可以创建一个等待响应的自定义方法，并在超时后关闭浏览器（如有必要）。

        int tryCount = 0;
        boolean desiredResponseReceived = false;
        while (desiredResponseReceived == false && tryCount < 20) {
            String statusText = (String) js.executeScript("return xhr.statusText;");
            if (statusText.indexOf("200") != -1) {
                desiredResponseReceived = true;
            }
            else {
                Thread.sleep(250);
                tryCount++;
            }
        }

        if (desiredResponseReceived == false) {
            driver.quit();
        }

如上所述，如果在5秒内xhr响应中没有出现“200”，此方法将关闭浏览器。（因为它在最终到达if (desiredResponseReceived == false)并关闭浏览器之前每隔250毫秒检查20次，然后关闭浏览器。）
