使用Selenium使用WindowHandles跟踪和迭代选项卡和窗口的最佳方法

我们正在使用Selenium webdriver为Internet Explorer 11进行UI测试。在经过测试的Web应用程序中,有几个屏幕弹出。 在几个测试中,我们最终得到三个browserwindows,还有三个Driver.WindowHandles。 要从一个WindowHandle切换到另一个WindowHandle,我们预计Driver.WindowHandles将像最旧的窗口一样排序,最新的窗口最后。 但情况并非如此:它完全是随机的!

因为windowhandle是一个GUID,所以我们最终使用WindowHandle GUID作为键创建一个字典,其中包含在浏览器窗口中加载的页面类型的值。 但是这也导致在关闭窗口时维护字典。

对于这么简单的事情来说,这似乎是很多工作。 有更好的解决方案吗?

当你说:你是非常正确的:

WindowHandles would be sorted like the oldest windows first and the newest windows last. But this is not the case: It is totaly random!

在一次讨论中,西蒙明确提到:

While the datatype used for storing the list of handles may be ordered by insertion, the order in which the WebDriver implementation iterates over the window handles to insert them has no requirement to be stable. The ordering is arbitrary.

因此,我们将引入一个WebDriverWait ,然后每次打开一个新的选项卡/窗口时收集窗口句柄,最后根据需要遍历窗口句柄和switchTo().window(newly_opened)

如果需要,请调整Test Environment [我的配置 – Selenium :3.5.3IEDriverServerIEDriverServer (64位)IE :v10.0 ]

Java的:

 package demo; import java.util.Iterator; import java.util.Set; import org.openqa.selenium.By; import org.openqa.selenium.JavascriptExecutor; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.ie.InternetExplorerDriver; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; public class NEW_TAB_Handling { public static void main(String[] args) { System.setProperty("webdriver.ie.driver", "C:\\Utility\\BrowserDrivers\\IEDriverServer.exe"); WebDriver driver = new InternetExplorerDriver(); driver.get("http://www.google.com"); String first_tab = driver.getWindowHandle(); System.out.println("Working on Google"); ((JavascriptExecutor) driver).executeScript("window.open('http://facebook.com/');"); WebDriverWait wait = new WebDriverWait(driver,5); wait.until(ExpectedConditions.numberOfWindowsToBe(2)); Set s1 = driver.getWindowHandles(); Iterator i1 = s1.iterator(); while(i1.hasNext()) { String next_tab = i1.next(); if (!first_tab.equalsIgnoreCase(next_tab)) { driver.switchTo().window(next_tab); System.out.println("Working on Facebook"); } } String second_tab = driver.getWindowHandle(); ((JavascriptExecutor) driver).executeScript("window.open('http://youtube.com/');"); wait.until(ExpectedConditions.numberOfWindowsToBe(3)); Set s2 = driver.getWindowHandles(); Iterator i2 = s2.iterator(); while(i2.hasNext()) { String next_tab = i2.next(); if (!first_tab.equalsIgnoreCase(next_tab) && !second_tab.equalsIgnoreCase(next_tab)) { driver.switchTo().window(next_tab); System.out.println("Working on Youtube"); } } driver.quit(); System.out.println("Quit the WebDriver instance"); } } 

控制台输出:

 Working on Google Working on Facebook Working on Youtube Quit the WebDriver instance
