你就快到了。如果您想要切换到一个窗口，首先将窗口id存储在一个数组中，然后切换到某个特定的窗口。像下面这样的一些事情。如果你需要更多的帮助，请告诉我。编码快乐。

Set handles = driver.getWindowHandles();
        String[] individualHandle = new String[handles.size()];
        Iterator it = handles.iterator();
        int i =0;
        while(it.hasNext())
        {
            individualHandle[i] = (String) it.next();
            i++;
        }

driver.switchTo().window(individualHandle[1]);

public static void switchWindow(String text) {
    WebDriver popup = null;
    Iterator<String> windowIterator = driver.getWindowHandles()
            .iterator();
    while (windowIterator.hasNext()) {
        String windowHandle = windowIterator.next();
        popup = driver.switchTo().window(windowHandle);
        String title = popup.getTitle();
        if (title.contains(text)) {
            break;
        }
    }
}

这将为您打开包含特定文本的任何窗口，您不必具体说明。

下面的方法将导航到特定窗口

public static void switchToParticularWindow(WebDriver driver, int index) throws InterruptedException {
        ArrayList<String> tabs = new ArrayList(driver.getWindowHandles());
        driver.switchTo().window(tabs.get(index));
        Thread.sleep(2000);
        logger.info("Switched to new tab");
    }

    driver.findElement(By.xpath("//*[@id=\"blueBarDOMInspector\"]/div/div/div/div[1]/a")).click();

    System.out.println(driver.getTitle());

}
