selenium - JMeter 的 WebDriver 的 Javascript 解释器无法访问第二个选项卡窗口

Question

我正在尝试使用以下代码运行 WebDriver Sampler：

var pkg = JavaImporter(org.openqa.selenium); //WebDriver classes
var support_ui = JavaImporter(org.openqa.selenium.support.ui.WebDriverWait); //WebDriver classes
var wait = new support_ui.WebDriverWait(WDS.browser, 5000);

WDS.sampleResult.sampleStart(); //captures sampler's start time
WDS.sampleResult.getLatency();
WDS.log.info("Sample started");

// Navigate to home
...

// Login
...

// Navigate to Messages
var messagesButton = WDS.browser.findElement(pkg.By.id('chat-button')); // saves the messages button into messagesButton
messagesButton.click(); // clicks the messages button which opens up link in a new tab
WDS.log.info("Clicked Messages Button");

var tabs = WDS.browser.getWindowHandles();
var tab = WDS.browser.getWindowHandle();

WDS.log.info("All Tabs: " + tabs);
WDS.log.info("Current Tab: " + tab);
WDS.log.info("Next Tab: " + tabs[tabs.size() - 1]);

WDS.browser.switchTo.window(tabs[tabs.size() - 1]);

// Load General Channel
var generalChannelButton = WDS.browser.findElement(pkg.By.linkText('general')); // saves the general channels button into generalChannelButton
messagesButton.click(); // clicks the messages button

WDS.sampleResult.sampleEnd();

在此，在我登录用户后，我指示他们单击消息按钮。当他们单击此按钮时，会打开一个新选项卡并运行自动 OAuth 流程。我想要测试做的是导航到打开的新选项卡，然后等待 OAuth 完全处理并发生最终重定向。一旦发生这种情况，我想点击一个按钮。

但是，现在当我转到通过消息按钮打开的选项卡时，我被卡住了。以下是打印出来的内容：

如您所见，All Tabs打印一个带有两个选项卡的数组，但是当我尝试访问索引 1 处的选项卡时，它打印出 null ...

如何访问第二个选项卡并等待它加载某个重定向 url，然后再继续？

更仔细地阅读 jmeter.log 文件：

TypeError: WDS.browser.switchTo.window is not a function in <eval> at line number 39

我的期望是您需要替换此行：

WDS.browser.switchTo.window(tabs[tabs.size() - 1]);

有了这个：

WDS.browser.switchTo().window(tabs[tabs.size() - 1]);

因为switchTo()是一个函数，因此它需要有尾括号。
