两个浏览器在Selenium中打开

Question

我使用两个类，一个是BaseCode，其中声明了所有基本方法。该类定义如下：

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());
                }
            }
}

现在我使用上面的launchBrowser()的第二课如下：

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());
        }
  }
}

当我运行此代码时，它打开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：

如果它停留在同一浏览器中，它将找到Search WebElement但它打开第二个浏览器。

任何人都可以帮助如何停止打开两个浏览器。

Answer 1

您正在调用以下代码两次：

driver = new ChromeDriver();

一旦进入LaunchBrowser方法，就在try catch之后。这就是你得到两个浏览器的原因。

Answer 2

您在类中的第一个函数中初始化chrome驱动程序2次

driver = new ChromeDriver();

Answer 3

我有同样的问题，但我发现在所有其他testNG注释之前我有“@BeforeSuite（alwaysRun = true）”。我在代码中没有@afterSuite（它可能忘记在其中一个测试后删除它。

脱下后它得到修复。
