java - 配置失败 : @BeforeMethod setup org. openqa.selenium.NoSuchSessionException : Session ID is null. 调用 quit() 后使用 WebDriver？

Question

我在这里发现了一些类似的问题( SessionNotFoundException: Session ID is null. Using WebDriver after calling quit()? (Selenium)

org.openqa.selenium.NoSuchSessionException: Session ID is null. Using WebDriver after calling quit()?)但他们都没有帮助我解决我的问题。任何帮助或建议将不胜感激。

就我而言，我使用的是 TestNG。我已经创建了主类

package base;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.BeforeTest;

public class MainClass {

      public WebDriver driver;
      public Properties CONFIG;
      public Properties XPATH;

    @BeforeSuite
    public void initialization() throws IOException {   
        String chromeDriverLocation = System.getProperty("user.dir")+"/src/main/java/driverlocation/chromedriver.exe";
        System.setProperty("webdriver.chrome.driver", chromeDriverLocation);

        driver = new ChromeDriver();
        System.out.println("Web Driver initilization has started...");
        System.out.println("In the before suite...");

        CONFIG = new Properties();
        String configLocation = System.getProperty("user.dir")+"/src/main/java/base/Config.properties";
        FileInputStream ip = new FileInputStream(configLocation);
        CONFIG.load(ip);

        XPATH = new Properties();
        String xpathLocation = System.getProperty("user.dir")+"/src/main/java/base/xpath.properties";
        FileInputStream xpathIp = new FileInputStream(xpathLocation);
        XPATH.load(xpathIp);
    }
     @AfterSuite
        public void tearDown() {
        System.out.println("Web Driver is closing...");
        System.out.println("it is epic...");
        driver.quit();
}
}

我有一个测试类，它扩展了 Main.Class

package Test.TileSearch;

import org.testng.annotations.Test;

import base.MainClass;

import org.testng.annotations.BeforeMethod;
import org.openqa.selenium.By;
import org.testng.annotations.AfterMethod;


public class Tile1City1 extends MainClass  {


     @BeforeMethod 
       public void setup() throws Exception {
          driver.get(CONFIG.getProperty("urlcentura"));
          driver.manage().window().maximize();
      }

      @AfterMethod 
      public void tearDown() {
          driver.quit();
      }


       @Test
      public void main1() throws Exception  
            driver.findElement(By.xpath().click();
            driver.findElement(By.xpath().click();
            driver.findElement(By.xpath().click();

            if(!driver.findElements(By.partialLinkText("Tile")).isEmpty()){
                    System.out.println("Tile is available there");
                }else{
                    System.out.println("Tile is not available there");
                }
      }

      @Test
      public void main1() throws Exception  
            driver.findElement(By.xpath().click();
            driver.findElement(By.xpath().click();
            driver.findElement(By.xpath().click();

            if(!driver.findElements(By.partialLinkText("Tile")).isEmpty()){
                    System.out.println("Tile is available there");
                }else{
                    System.out.println("Tile is not available there");
                }
      }
    }

控制台出现错误

只有一个测试正在运行，其他测试总是会跳过。基本上问题是我正在使用 WebDriver 的静态属性，该属性不应在不同的测试运行之间共享。有人知道如何解决这个问题吗？

Answer 1

您似乎正在退出 Tile1City1 中的驱动程序

 @AfterMethod 
  public void tearDown() {
      driver.quit();
  }

因此，您在 @BeforeSuite 中打开驱动程序，然后在一次测试后退出它，并且不再重新打开它。我可能误读了代码，但这似乎就是正在发生的事情。

如果您希望每个测试都有一个新的驱动程序，则还需要在 @BeforeMethod 中打开每个测试的驱动程序。

如果您想在每次测试中重复使用相同的驱动程序，请删除我从 Tile1City1 引用的代码
