java - Selenium switchTo 返回错误 org.openqa.selenium.WebDriverException : unknown error: cannot determine loading status

Question

我有点击超链接的场景，并会打开新标签(点击超链接后 Activity 窗口将移动到新标签)

当我尝试使用 switchTo() 方法将 webdriver 移动到新选项卡时，然后是 WebDriverWait.until 浏览器自动关闭并出现错误

org.openqa.selenium.WebDriverException: unknown error: cannot determine loading status
from no such execution context
  (Session info: chrome=73.0.3683.103)

我使用 System.out.println(driver.getWindowHandle())，我可以看到驱动程序移动到新选项卡。

我如何解决上述错误？我尝试使用 Iterator for loop into windowHandle

似乎无法使用 WebDriverWait.until(ExpectedConditions) 来等待新标签页。总是报错 cannot determine loading status from no such execution context

奇怪的是，我可以使用 Thread.sleep(1000)。

在这种情况下如何避免使用 Thread.sleep？因为隐式等待也行不通

使用 Thread.sleep() 的工作代码

public class MyCode {
    private WebDriver driver;
    private WebDriverWait wait;

    @Test
    public void openPrestaShopFromDemoWebsite() {
        System.setProperty("webdriver.chrome.driver", "chromedriver");
        ChromeOptions chromeOptions = new ChromeOptions()
                .addArguments("--start-maximized", "--incognito");

        driver = new ChromeDriver(chromeOptions);
        driver.navigate().to("http://demo.prestashop.com");
        wait = new WebDriverWait(driver, 10);
        wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("loadingMessage")));

        driver.switchTo().frame("framelive");
        String parentTab = driver.getWindowHandle();
        driver.findElement(By.partialLinkText("Ecommerce software by PrestaShop")).click();

        Set<String> windowHandles = driver.getWindowHandles();
        Iterator<String> it = windowHandles.iterator();

        while (it.hasNext()) {
            String newTab = it.next();

            if (!parentTab.equals(newTab)) {
                driver.switchTo().window(newTab);

                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                wait.until(ExpectedConditions.titleIs("Create and develop your business with PrestaShop"));
                driver.close();
            }
        }

        driver.switchTo().window(parentTab);
        driver.switchTo().frame("framelive");
        assertThat(driver.findElement(By.linkText("Personal info")).isDisplayed());

        driver.quit();

    }
}

代码无效(无法从没有此类执行上下文的情况下确定加载状态)

public class MyCode {
    private WebDriver driver;
    private WebDriverWait wait;
    private WebElement element;

    @Test
    public void openPrestaShopFromDemoWebsite() {
        System.setProperty("webdriver.chrome.driver", "chromedriver");
        ChromeOptions chromeOptions = new ChromeOptions()
                .addArguments("--start-maximized", "--incognito");

        driver = new ChromeDriver(chromeOptions);
        driver.navigate().to("http://demo.prestashop.com");
        wait = new WebDriverWait(driver, 10);
        wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("loadingMessage")));

        driver.switchTo().frame("framelive");
        String parentTab = driver.getWindowHandle();
        driver.findElement(By.partialLinkText("Ecommerce software by PrestaShop")).click();

        Set<String> windowHandles = driver.getWindowHandles();
        Iterator<String> it = windowHandles.iterator();

        while (it.hasNext()) {
            String newTab = it.next();

            if (!parentTab.equals(newTab)) {
                driver.switchTo().window(newTab);

                wait.until(ExpectedConditions.titleIs("Create and develop your business with PrestaShop"));
                driver.close();
            }
        }

        driver.switchTo().window(parentTab);
        driver.switchTo().frame("framelive");
        assertThat(driver.findElement(By.linkText("Personal info")).isDisplayed());

        driver.quit();

    }
}

几天来我一直遇到同样的问题，看来这实际上是 chromedriver 的问题。对我有用的解决方案是将以下标志/参数添加到您的 chromedriver 选项中:

--disable-site-isolation-trials

Here是我指的 chromedriver 问题(和解决方案)。

如果 flag 不起作用，您也可以尝试升级到 chromedriver v75
