兩個瀏​​覽器在Selenium中打開

Question

我使用了兩個類，其中一個是BaseCode，其中聲明瞭所有基本方法。類的定義如下：

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()); 
       } 
      } 
} 

現在我在哪裏使用上述launchBrowser()第二類如下：

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()); 
     } 
    } 
} 

當我運行該代碼，它的開口兩個瀏覽器，而不是一個。第一個已經重定向到flipkart.com，但第二個只顯示一個空白窗口。控制檯輸出如下：

[RemoteTestNG] detected TestNG version 6.12.0

如果當時留在同一個瀏覽器，它會發現Search WebElement但其打開第二個瀏覽器。

任何人都可以幫助如何停止打開兩個瀏覽器。就在嘗試捕捉後，一旦在LaunchBrowser方法，一旦

driver = new ChromeDriver(); 

：

Answer 1

你兩次調用下面的代碼。這就是爲什麼你有兩個瀏覽器。

Answer 2

你在課堂上初始化鉻司機2次在一個函數一個

driver = new ChromeDriver(); 

Answer 3

我有同樣的問題，但我發現我有「@BeforeSuite（alwaysRun =真）」 之前所有其他testNG註釋。我並沒有在代碼@afterSuite（它可能通過你的代碼忘了一個測試之後將其刪除。

取下來它得到解決後。
