Selenium:处理随机弹出的 window

Selenium : Handle a window that popups up randomly

我们有一项收集客户反馈的功能。为此,当用户注销时,window 随机弹出 - 并非每次都针对每个客户。 我想在我的自动化代码中处理这个。

目前,在注销时,我期待 window 并切换到它,当弹出窗口 window 没有出现时,该代码失败。

处理此问题的最佳方法是什么。

这是我目前所拥有的...

    public static void waitForNumberOfWindowsToEqual(final int numberOfWindows) {


    ExpectedCondition<Boolean> expectation = new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver driver) {
            return (driver.getWindowHandles().size() == numberOfWindows);
        }
    };

    WebDriverWait wait = new WebDriverWait(driver, BrowserFactory.explicitWait);


    wait.until(expectation);
}

如果可能,理想的做法是查看源代码以确定弹出窗口 window 是否会出现,但是如果这无法实现,您可以采用以下方法:

// Get the number of windows open before clicking the log out button.    
int numberOfWindowsBeforeLogOut = driver.getWindowHandles().size();

// Click the log out button.
logOutButton.click();

// Check how many windows are open after clicking the log out button.
int numberOfWindowsAfterLogOut = driver.getWindowHandles().size();

// Now compare the number of windows before and after clicking the log out 
// button in a condition statement.
if (numberOfWindowsBeforeLogOut < numberOfWindowsAfterLogOut) {
   // If there is a new window available, switch to it.
   driver.switchTo().window(titleOrWindowHandle);
}

我会用 try/catch 来处理缺少弹出窗口 window。这是一个例子:

try {
    WebDriverWait winwait = new WebDriverWait(driver, 3);
    String mainWindow = driver.getWindowHandle();

    // wait for 2 windows and get the handles
    Set<String> handles = winwait.until((WebDriver drv) -> {
        Set<String> items = drv.getWindowHandles();
        return items.size() == 2 ? items : null;
    });

    // set the context on the last opened window
    handles.remove(mainWindow);
    driver.switchTo().window(handles.iterator().next());

    // close the window
    driver.close();

    // set the context back to the main window
    driver.switchTo().window(mainWindow);

} catch (TimeoutException ex) {
    System.out.println("No window present within 3 seconds");
}

如果您没有获得所需的 window,代码将抛出一个 TimeoutException。因此,将 wait.until(expectation) 放入 try 块中并捕获异常。在代码中,

try {
    wait.until(expectation);
} catch (TimeoutException ex) {
    System.out.println("Nowindow This Time");
}
