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

Question

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

1. 将商品添加到购物车(将会显示已添加商品的数量)
2. 删除浏览器上的cookies，
3. 关闭浏览器
4. 重新启动浏览器
5. 检查购物车计数项目是否仍然存在

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.")
}

@AfterTest代码

@AfterTest
    public void closeBrowser(){

        driver.close();
        ExistingmozillaBrowser=null;

    }

获取下面的错误日志

关闭浏览器后，重启后测试似乎无法继续。任何帮助将不胜感激。谢谢。

Answer 1

我认为这种方式应该可行:

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);
  

• 将商品添加到您的购物车

• 关闭驱动程序(不要退出)

  driver.close();
  

• 在后台，delete user-dir 即 D:/temp/ ，其中包含浏览器配置文件。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);
  

PS:希望对您有所帮助。我已经看到此类代码可用于测试“记住我”功能。我不太确定购物车。
