无法删除selenium中的所有Cookie

Question

配置：

OS : Ubuntu
Java version : 8
Selenium : 3.8.0
ChromeDriver : 2.33
Chrome version : 60

我正在自动化一个应用程序，我必须使用社交媒体登录系统

输入手机号码后，会要求输入密码和社交媒体图标。如果我点击让我们说google plus，它会打开谷歌加登录窗口，然后我必须提供凭证，然后窗口自动关闭，用户登录。如图所示

我的问题是，从我的应用程序退出后，如果我再次尝试使用google plus登录，那么它会执行自动登录（第二次它不会要求谷歌加凭据，因为谷歌加会话cookie都在那里）

所以在我的脚本中，我试图在第一次测试后删除所有的cookie，但它不是我尝试过的代码行：

driver.manage().deleteAllCookies();

参考完整测试如下：

@Test
public void newUserRegistration_GooglePlus_ForAlreadyExistEmail() throws IOException, InterruptedException, JSONException
{
    LogoutAnalyzer.checkLogout();
    loginpage.sendUsername(excel.getCellData(6, 18, 1));
    CommonMethods.waitUntilLoaderGetInvisible(driver);
    TakeScreenshot.passedScreenShot("Username");
    LogWriter.logger.info("Mobile number has entered");
    loginpage.clickSubmitButton();
    CommonMethods.waitUntilLoaderGetInvisible(driver);
    LogWriter.logger.info("Submit button clicked");

    if(loginpage.otpTextbox.size()>0)
    {
        String OTP = otpreader.getOTP(excel.getCellData(6, 18, 1));
        LogWriter.logger.info("Got the OTP via API call OTP is "+OTP);
        loginpage.enterOTP(OTP);
        TakeScreenshot.passedScreenShot("OTP_Entered");
        LogWriter.logger.info("OTP Entered");
        loginpage.clickConfirmCodeButton();
        CommonMethods.waitUntilLoaderGetInvisible(driver);  
        LogWriter.logger.info("Submit button clicked");
        TakeScreenshot.passedScreenShot("Profile_Info");
        loginpage.clickGooglePlusIcon();
        Thread.sleep(5000);
        LogWriter.logger.info("Switch to Google Plus window");
        CommonMethods.switchWindow(driver);
        CommonMethods.waitForElementVisibility(driver, new RCONGooglePlusPage(driver).usernameField);
        TakeScreenshot.passedScreenShot("Google Window");
        sm_helper.googlePlusLogin(excel.getCellData(6, 18, 2), excel.getCellData(6, 18, 3));

        CommonMethods.switchToParentWindow(driver);
        LogWriter.logger.info("Switched back to RContacts window");
        CommonMethods.waitUntilLoaderGetInvisible(driver);
        Assert.assertEquals(loginpage.getValidationMessage(), PropertyFileReader.getProperty("emailAlreadyExistMessage"));
        LogWriter.logger.info(PropertyFileReader.getProperty("emailAlreadyExistMessage"));
    }
    else
    {
        TakeScreenshot.passedScreenShot("Already_registered_User");
        LogWriter.logger.info("This user is already a registered user");
    }

    driver.manage().deleteAllCookies();
    LogWriter.logger.info("all cookies deleted");
}
