两个浏​​览器在Selenium中打开

Question

我使用了两个类，其中一个是BaseCode，其中声明了所有基本方法。类的定义如下：

package CodeBase; 

import java.util.concurrent.TimeUnit; 

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

public class BaseCode { 

    //All the Universal variables for TestBase class are declared here: 
     public static WebDriver driver = null; 

    //All Universal Methods for TestBase class are declared here: 
      public void launchBrowser(String baseUrl) throws Exception{ 
       try { 
         System.out.println("Launching the Chrome Browser"); 
         String driverpath = "E:\\Learning\\Selenium\\Drivers\\ChromeDriver\\chromedriver.exe"; 
         System.setProperty("webdriver.chrome.driver",driverpath); 
         driver = new ChromeDriver(); 
         driver.manage().window().maximize(); 
         System.out.println("Opening URL: " + baseUrl); 
         driver.navigate().to(baseUrl); 
         TimeUnit.SECONDS.sleep(5); 
      }catch(Exception E) { 
       System.out.println(E.getMessage() +"\n" + E.getStackTrace()); 
       } 
      } 
} 

现在我在哪里使用上述launchBrowser()第二类如下：

package projectpack; 

import java.io.File; 
import java.io.IOException; 
import java.util.concurrent.TimeUnit; 
import org.apache.commons.io.FileUtils; 
import org.openqa.selenium.By; 
import org.openqa.selenium.OutputType; 
import org.openqa.selenium.TakesScreenshot; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.chrome.ChromeDriver; 
import org.testng.annotations.Test; 
import CodeBase.BaseCode; 



public class Flipkart { 

    public static BaseCode B = new BaseCode(); 

    @Test 
    public void testFlipkart() { 
     String url = "https://www.flipkart.com/"; 
     try { 
      B.launchBrowser(url); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     WebDriver driver = new ChromeDriver(); 
     try { 
     TimeUnit.SECONDS.sleep(5); 
     this.takeSnapShot(driver, "E://Learning/Selenium/Screenhots/Flipkart/Intro.jpeg"); 
     String Prod1 = "philips bt120"; 
     WebElement Search = driver.findElement(By.cssSelector("._1WMLwI .LM6RPg")); 
     Search.sendKeys(Prod1); 
     this.takeSnapShot(driver, "E://Learning/Selenium/Screenhots/Flipkart/Step1.jpeg"); 
     Search.submit(); 
     this.takeSnapShot(driver, "E://Learning/Selenium/Screenhots/Flipkart/Step2.jpeg"); 
     WebElement Object = driver.findElement(By.xpath("//*[@id=\"container\"]/div/div[1]/div/div[2]/div/div[2]/div/div[3]/div/div/div[1]/div/a[2]")); 
     Object.click(); 
     this.takeSnapShot(driver, "E://Learning/Selenium/Screenhots/Flipkart/Step3.jpeg"); 
     driver.quit(); 
     }catch(Exception E) { 
      System.out.println(E.getMessage() + "\n" + E.getStackTrace()); 
     } 
    } 
} 

当我运行该代码，它的开口两个浏览器，而不是一个。第一个已经重定向到flipkart.com，但第二个只显示一个空白窗口。控制台输出如下：

[RemoteTestNG] detected TestNG version 6.12.0

如果当时留在同一个浏览器，它会发现Search WebElement但其打开第二个浏览器。

任何人都可以帮助如何停止打开两个浏览器。就在尝试捕捉后，一旦在LaunchBrowser方法，一旦

driver = new ChromeDriver(); 

：

Answer 1

你两次调用下面的代码。这就是为什么你有两个浏览器。

Answer 2

你在课堂上初始化铬司机2次在一个函数一个

driver = new ChromeDriver(); 

Answer 3

我有同样的问题，但我发现我有“@BeforeSuite（alwaysRun =真）” 之前所有其他testNG注释。我并没有在代码@afterSuite（它可能通过你的代码忘了一个测试之后将其删除。

取下来它得到解决后。
