How to switch between 2 browsers in selenium webdriver with java

问题

I'm working on selenium webdriver with java. I want to open a browser perform some actions in it. Then open another browser and do the same actions in it, then go back to first browser and perform some actions.

How can i switch between 2 browsers (not the switching between 2 tabs)?

This is what i have done:

@BeforeTest
    public void beforeTest() throws BiffException, IOException,InterruptedException {
System.setProperty("webdriver.chrome.driver","D:\\MyProjects\\SeleniumTrials\\chromedriver_win32\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get(properties.getProperty("VAR_BASEURL"));
        driver.manage().window().maximize();
      WebDriver  tempDriver = new ChromeDriver();
        tempDriver.get(properties.getProperty("VAR_BASEURL"));
        tempDriver.manage().window().maximize();
}
@Test
    public void playTournament() throws InterruptedException, BiffException,IOException {
    int rowNumber = 1;
    int newRowNumber=2;
    WebElement login =driver.findElement(By.xpath(properties.getProperty("VAR_LOGIN"))); 
    login.click();
    Thread.sleep(1000);
    WebElement username = driver.findElement(By.xpath(properties.getProperty("VAR_USERNAME")));
    username.clear();
    username.sendKeys(getCellContent(0, rowNumber));
    Thread.sleep(1000);
    WebElement password = driver.findElement(By.xpath(properties.getProperty("VAR_PASSWORD")));
    password.clear();
    password.sendKeys(getCellContent(1, rowNumber));
    Thread.sleep(1000);
    WebElement continueButton = driver.findElement(By.xpath(properties.getProperty("VAR_CONTINUE")));
    continueButton.click();
    Thread.sleep(1000);

   WebElement login =tempDriver .findElement(By.xpath(properties.getProperty("VAR_LOGIN"))); 
   login.click();
   Thread.sleep(1000);
   WebElement username = tempDriver .findElement(By.xpath(properties.getProperty("VAR_USERNAME")));
   username.clear();
   username.sendKeys(getCellContent(0, rowNumber));
   Thread.sleep(1000);
   WebElement password = tempDriver .findElement(By.xpath(properties.getProperty("VAR_PASSWORD")));
   password.clear();
   password.sendKeys(getCellContent(1, rowNumber));
   Thread.sleep(1000);
   WebElement continueButton = tempDriver .findElement(By.xpath(properties.getProperty("VAR_CONTINUE")));
   continueButton.click();

回答1:

When you do

WebDriver driver = new ChromeDriver();
driver = new ChromeDriver();

You reinitialize the driver instance, witch means you loose the first browser. You can see it by calling getWindowHandles()

driver.getWindowHandles(); // will be 1, the last open browser

If you want to different browsers use temporary driver

WebDriver driver = new ChromeDriver();
WebDriver tempDriver = new ChromeDriver();

// do some stuff on tempDriver

tempDriver.close();

// continue working with the first driver

I guess this is what you are looking for,

keep two browser objects
define a method which does a set of operations on a browser
call this method first using the first browser and again using the second browser
then perform some more action on the first browser

I have solved switching between browser drivers in a Typescript but it should be easy for you to understand the methodology and implement it in the Java.

@TDriver.ts

    import {browser, ProtractorBrowser} from 'protractor';

    export class TDriver {
      private static defaultBrowser: ProtractorBrowser = browser;
      private static activeBrowser;

      public async newDriver() {
        const secondDriver = TDriver.activeBrowser.forkNewDriverInstance();
        await this.setActiveBrowser(secondDriver);
        }

      public setActiveBrowser(driver: ProtractorBrowser) {
        TDriver.activeBrowser = driver;
      }

      public getActiveBrowser() {
        return TDriver.activeBrowser;
      }

      public setDefaultBrowserActive() {
        TDriver.activeBrowser = TDriver.defaultBrowser;
      }

    }

@Test.ts

import {by} from 'protractor';
import {TDriver} from '../driver/TDriver';

export class Test {
  private driver = new TDriver().getActiveBrowser();

   this.driver.findElement(by.xpath("xPathSelector")).click(); //this click in first native driver instance

   await new TDriver().newDriver(); //create new driver and switch to it!

   this.driver.findElement(by.xpath("xPathSelector")).click(); //this click in the second driver instance

   await new TDriver().setDefaultBrowserActive(); //now we switch and use again native driver

   this.driver.findElement(by.xpath("xPathSelector")).click(); //this click in first native driver instance
}

Those methods enables you to perform test in native browser then create new instance and continue test in second browser driver. Works in my project.
