我正在尝试使用以下代码运行WebDriver采样器：
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();
在这种情况下，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，将打开一个新选项卡并运行自动OAuth流程。我希望测试执行的操作是导航到打开的新选项卡，然后等待OAuth完全处理并完成最终重定向。一旦发生这种情况，我想单击一个按钮。
但是，当我转到通过消息按钮打开的选项卡时，现在我陷入困境。这是打印出来的内容：

如您所见，All Tabs打印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 ...
如何继续访问第二个选项卡并等待其加载特定的重定向URL，然后继续？

更仔细地阅读jmeter.log文件：
<template>
<label class="wrapper" :data-error="validation && errors.first(name)" :class="{ error: errors && errors.first(name), label }">
<span class="label" v-if="label">{{label}}</span>
<div class="input" :class="{
'input--search': type === 'search'
}">
<input
v-if="validation"
:aria-label="ariaLabel"
v-shortkey.focus="shortKey"
:disabled="disabled"
:type="type"
:class="classes"
:value="value"
:name="name"
:placeholder="placeholder"
@search="reset"
@input="update"
v-validate="validation"
:autocomplete="autocomplete"
/>
<input
v-else
:aria-label="ariaLabel"
v-shortkey.focus="shortKey"
:disabled="disabled"
:type="type"
:class="classes"
:value="value"
:name="name"
:placeholder="placeholder"
@search="reset"
@input="update"
:autocomplete="autocomplete"
/>
<Icon class="icon" v-if="iconName && !value" :name="iconName" />
</div>
</label>
</template>
我的期望是您需要替换此行：
<template>
<form class="form" v-on:submit.prevent>
<slot />
<Input
v-if="isLabel && displayLabel"
class="label"
ref="label"
type="text"
:label="$t('subscriptions.new.label-placeholder')"
name="label"
:validation="{ required: true }"
:value="label"
@input="onLabelChange"
/>
<hr />
<Terms
v-if="!termsAccepted"
:value="terms"
@input="onTermsToggle"
/>
<Button
class="submit button-next"
submit
:disabled="nextDisabled"
@click="next"
>
{{ $t('subscriptions.new.next') }}
</Button>
</form>
</template>
与此：
TypeError: WDS.browser.switchTo.window is not a function in <eval> at line number 39
因为switchTo()是一个函数，因此它需要带尾括号。

结果是，即使您打印出结果的getWindowHandles()，“ javascript”解释器也不会将Array解释为Set，而是解释为typeof。 getWindowHandles()中的object。
因此，您要做的是从Iterator中创建一个Set，然后以比Javascript类型更类似于Java的方式对其进行迭代。
var tabs = WDS.browser.getWindowHandles();
var tabsIterator = tabs.iterator();
var tabsArr = [];
while(tabsIterator.hasNext()) {
tabsArr.push(tabsIterator.next());
}
var chatTab = tabsArr[tabsArr.length - 1];
WDS.browser.switchTo().window(chatTab);
WDS.log.info("Navigated to Chat Tab");
