Java Selenium WebDriver-在测试期间删除Cookie并重新启动浏览器

我有一个测试用例要测试的是，在删除cookie并重新启动浏览器后，购物车项目是否仍然存在

将项目添加到购物车（将对指定的添加项目数进行计数）

删除浏览器上的cookies

关闭浏览器

重新启动浏览器

检查是否购物车计数项目仍然存在

我的主要代码如下

// 1. Add items to shopping cart
// code go here

// 2. Clear the cookies on the browser
driver.manage().deleteAllCookies();         
driver.navigate().refresh();
// 3. Close the browser
driver.close();                             

ProfilesIni firProfiles = new ProfilesIni();        
FirefoxProfile wbdrverprofile = firProfiles.getProfile("default");  
// 4. Relaunch the browser      
driver = new FirefoxDriver(wbdrverprofile);                 
driver.get("http://www.google.com");        

Boolean isCartCountExists = driver.findElements(By.id(cartCount)).size()!=0;
if(isCartCountExists == true){
    System.out.println("Test Failed.");
}else{
    System.out.println("Test Passed.")
}

@postest

code

@AfterTest
    public void closeBrowser(){

        driver.close();
        ExistingmozillaBrowser=null;

    }

获取下面的错误日志

似乎关闭浏览器后，重新启动后测试无法继续。任何帮助都将不胜感激。谢谢。

我认为这种方法应该有效：

步骤（这是一个chrome示例）：

• 在浏览器配置中使用

  user dir

  参数：

  System.setProperty("webdriver.chrome.driver", "res/chromedriver.exe");
  DesiredCapabilities capabilities = DesiredCapabilities.chrome();
  ChromeOptions options = new ChromeOptions();
  options.addArguments("test-type");
  options.addArguments("start-maximized");
  options.addArguments("user-data-dir=D:/temp/");
  capabilities.setCapability("chrome.binary","res/chromedriver.exe");
  capabilities.setCapability(ChromeOptions.CAPABILITY,options);
  WebDriver driver = new ChromeDriver(capabilities);
  

• 将项目添加到您的购物车中

• 关闭驱动程序（不要退出）

• 在后台，用户目录是具有浏览器配置文件的

  D:/temp/

  。这将是cookie删除部分

• 重新初始化驱动程序并验证购物车是否为空

  driver = new ChromeDriver(capabilities);
  

---

附言：我希望这有帮助。我已经看到这种类型的代码可以用来测试“记住我”的功能。我对购物车不是很确定。

Java:

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.WebDriver;


private static WebDriver driver;

public static void restartDriver() {
    driver.manage().deleteAllCookies();         // Clear Cookies on the browser
    driver.quit();
    driver = null;
    driver = new ChromeDriver();

}

---

这是启动会话的最短方法。

请发布所有测试代码。在

driver.close（）

之后，您必须重新初始化

driver

。尽管使用cookies的一种方法是使用

user dir

参数。

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.WebDriver;


private static WebDriver driver;

public static void restartDriver() {
    driver.manage().deleteAllCookies();         // Clear Cookies on the browser
    driver.quit();
    driver = null;
    driver = new ChromeDriver();

}
