Selenium c# - 清除缓存和浏览数据

Question

在我的测试脚本中，我让 selenium 打开了 chrome 设置页面。在该页面上，我希望它选择“清除数据”按钮。

    driver.FindElement(By.CssSelector("* /deep/ #clearBrowsingDataConfirm"));

我收到一条错误消息，提示找不到元素。我也尝试过仅使用“ID”。有没有另一种方法可以做到这一点。

这是 @Lanki 的 c# 版本，但如果尚未选中，请确保单击“基本”选项卡、“所有时间”时间范围并单击浏览、Cookie 和缓存复选框。谢谢@Lanki！

    private static IWebElement expandRootElement(IWebElement element) {
        return (IWebElement)((IJavaScriptExecutor)driver).ExecuteScript("return arguments[0].shadowRoot", element);
    }

    private static void clickSettingsCheckbox(IWebElement chkBox) {
        string check = chkBox.GetAttribute("checked");
        if (check == null) chkBox.Click();
    }

    public static void clearCacheAndCookies() {

        driver.Navigate().GoToUrl("chrome://settings/clearBrowserData");
        driver.SwitchTo().ActiveElement();

        IWebElement root1 = driver.FindElement(By.CssSelector("settings-ui"));
        IWebElement shadowRoot1 = expandRootElement(root1);
        IWebElement root2 = shadowRoot1.FindElement(By.CssSelector("settings-main"));
        IWebElement shadowRoot2 = expandRootElement(root2);
        IWebElement root3 = shadowRoot2.FindElement(By.CssSelector("settings-basic-page"));
        IWebElement shadowRoot3 = expandRootElement(root3);
        IWebElement root4 = shadowRoot3.FindElement(By.CssSelector("settings-section > settings-privacy-page"));
        IWebElement shadowRoot4 = expandRootElement(root4);
        IWebElement root5 = shadowRoot4.FindElement(By.CssSelector("settings-clear-browsing-data-dialog"));
        IWebElement shadowRoot5 = expandRootElement(root5);
        IWebElement root6 = shadowRoot5.FindElement(By.CssSelector("#clearBrowsingDataDialog"));

        IWebElement root7 = root6.FindElement(By.CssSelector("cr-tabs[role='tablist']"));
        IWebElement shadowRoot7 = expandRootElement(root7);
        IWebElement root8 = shadowRoot7.FindElement(By.CssSelector("div[class='tab selected']"));
        IWebElement root9 = shadowRoot7.FindElement(By.CssSelector("div[class='tab']"));

        if (!root8.Text.Equals("Basic")) root9.Click();   // Select Basic tab if not selected
        
        IWebElement rootDropDown = root6.FindElement(By.Id("clearFromBasic"));
        IWebElement shadowDropDown = expandRootElement(rootDropDown);
        IWebElement timeRange = shadowDropDown.FindElement(By.Id("dropdownMenu"));
        var selectElement = new SelectElement(timeRange);
        selectElement.SelectByText("All time");

        clickSettingsCheckbox(root6.FindElement(By.Id("browsingCheckboxBasic")));
        clickSettingsCheckbox(root6.FindElement(By.Id("cookiesCheckboxBasic")));
        clickSettingsCheckbox(root6.FindElement(By.Id("cacheCheckboxBasic")));

        IWebElement clearDataButton = root6.FindElement(By.CssSelector("#clearBrowsingDataConfirm"));

        clearDataButton.Click();

        var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
        wait.Until(wd => wd.Url.StartsWith("chrome://settings"));
        Thread.Sleep(300);

        return;
    }

那个按钮真的很难够到，因为聚合物。 试试这个，它对我有用。

using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace Selenium_test
{
    class Program
    {
        static IWebDriver driver;

        static void Main(string[] args)
        {
            driver = new ChromeDriver();
            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
            driver.Navigate().GoToUrl("chrome://settings/clearBrowserData");

            IWebElement root1 = driver.FindElement(By.CssSelector("settings-ui"));
            IWebElement shadowRoot1 = expandRootElement(root1);
            IWebElement root2 = shadowRoot1.FindElement(By.CssSelector("settings-main"));
            IWebElement shadowRoot2 = expandRootElement(root2);
            IWebElement root3 = shadowRoot2.FindElement(By.CssSelector("settings-basic-page"));
            IWebElement shadowRoot3 = expandRootElement(root3);
            IWebElement root4 = shadowRoot3.FindElement(By.CssSelector("settings-section > settings-privacy-page"));
            IWebElement shadowRoot4 = expandRootElement(root4);
            IWebElement root5 = shadowRoot4.FindElement(By.CssSelector("settings-clear-browsing-data-dialog"));
            IWebElement shadowRoot5 = expandRootElement(root5);
            IWebElement root6 = shadowRoot5.FindElement(By.CssSelector("#clearBrowsingDataDialog"));
            IWebElement root7 = root6.FindElement(By.CssSelector("cr-tabs[role='tablist']"));

            root7.Click();

            IWebElement clearDataButton = root6.FindElement(By.CssSelector("#clearBrowsingDataConfirm"));

            clearDataButton.Click();
        }

        private static IWebElement expandRootElement(IWebElement element)
        {
            return (IWebElement)((IJavaScriptExecutor)driver).ExecuteScript("return arguments[0].shadowRoot", element);
        }
    }
}

由于我是新手，我无法投票支持@Lanki 的回答。 它就像一个魅力。

这是同一脚本的 JAVA 版本：

WebElement root1 = driver.findElement(By.cssSelector("settings-ui"));
WebElement shadowRoot1 = expandRootElement(root1);
WebElement root2 = shadowRoot1.findElement(By.cssSelector("settings-main"));
WebElement shadowRoot2 = expandRootElement(root2);
WebElement root3 = shadowRoot2.findElement(By.cssSelector("settings-basic-page"));
WebElement shadowRoot3 = expandRootElement(root3);
WebElement root4 = shadowRoot3.findElement(By.cssSelector("settings-section > settings-privacy-page"));
WebElement shadowRoot4 = expandRootElement(root4);
WebElement root5 = shadowRoot4.findElement(By.cssSelector("settings-clear-browsing-data-dialog"));
WebElement shadowRoot5 = expandRootElement(root5);
WebElement root6 = shadowRoot5.findElement(By.cssSelector("#clearBrowsingDataDialog"));
WebElement root7 = root6.findElement(By.cssSelector("cr-tabs[role='tablist']"));

root7.click();

WebElement clearDataButton = root6.findElement(By.cssSelector("#clearBrowsingDataConfirm"));

clearDataButton.click();
