Selenium - Multi Browser Testing

用户可以同时在多个浏览器中执行脚本。出于演示目的，我们将使用与 Selenium Grid 相同的场景。在 Selenium Grid 示例中，我们已经远程执行了脚本；在这里我们将本地执行脚本。

Users can execute scripts in multiple browsers simultaneously. For demonstration, we will use the same scenario that we had taken for Selenium Grid. In the Selenium Grid example, we had executed the scripts remotely; here we will execute the scripts locally.

首先，确保您下载了合适的驱动程序。有关下载 IE 和 Chrome 驱动程序，请参阅“Selenium Grid”一章。

First of all, ensure that you have appropriate drivers downloaded. Please refer the chapter "Selenium Grid" for downloading IE and Chrome drivers.

Example

为了演示，我们将在所有浏览器中同时执行百分比计算器。

For demonstration, we will perform percent calculator in all the browsers simultaneously.

package TestNG;

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.*;
import org.testng.annotations.*;

public class TestNGClass {
   private WebDriver driver;
   private String URL = "http://www.calculator.net";

   @Parameters("browser")
   @BeforeTest
   public void launchapp(String browser) {

      if (browser.equalsIgnoreCase("firefox")) {
         System.out.println(" Executing on FireFox");
         driver = new FirefoxDriver();
         driver.get(URL);
         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
         driver.manage().window().maximize();
      } else if (browser.equalsIgnoreCase("chrome")) {
         System.out.println(" Executing on CHROME");
         System.out.println("Executing on IE");
         System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
         driver = new ChromeDriver();
         driver.get(URL);
         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
         driver.manage().window().maximize();
      } else if (browser.equalsIgnoreCase("ie")) {
         System.out.println("Executing on IE");
         System.setProperty("webdriver.ie.driver", "D:\\IEDriverServer.exe");
         driver = new InternetExplorerDriver();
         driver.get(URL);
         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
         driver.manage().window().maximize();
      } else {
         throw new IllegalArgumentException("The Browser Type is Undefined");
      }
   }

   @Test
   public void calculatepercent() {
      // Click on Math Calculators
      driver.findElement(By.xpath(".//*[@id = 'menu']/div[3]/a")).click();

      // Click on Percent Calculators
      driver.findElement(By.xpath(".//*[@id = 'menu']/div[4]/div[3]/a")).click();

      // Enter value 10 in the first number of the percent Calculator
      driver.findElement(By.id("cpar1")).sendKeys("10");

      // Enter value 50 in the second number of the percent Calculator
      driver.findElement(By.id("cpar2")).sendKeys("50");

      // Click Calculate Button
      driver.findElement(By.xpath(".//*[@id = 'content']/table/tbody/tr/td[2]/input")).click();

      // Get the Result Text based on its xpath
      String result =
         driver.findElement(By.xpath(".//*[@id = 'content']/p[2]/span/font/b")).getText();

      // Print a Log In message to the screen
      System.out.println(" The Result is " + result);

      if(result.equals("5")) {
         System.out.println(" The Result is Pass");
      } else {
         System.out.println(" The Result is Fail");
      }
   }

   @AfterTest
   public void closeBrowser() {
      driver.close();
   }
}

创建一个 XML，它将帮助我们对浏览器名称参数化，并且不要忘记提及 parallel="tests" 才能在所有浏览器中同时执行。

Create an XML which will help us in parameterizing the browser name and don’t forget to mention parallel="tests" in order to execute in all the browsers simultaneously.

右键单击 XML 文件并选择“作为”>>“TestNG”套件运行脚本，如下所示。

Execute the script by performing right-click on the XML file and select 'Run As' >> 'TestNG' Suite as shown below.

Output

浏览器将同时启动，结果将打印在控制台中。

All the browser would be launched simultaneously and the result would be printed in the console.

Note − 为了在 IE 中成功执行，请确保在“IE 选项”的“安全”选项卡下的复选框“启用保护模式”在所有区域中均已选中或取消选中。

Note − To execute on IE successfully, ensure that the check box 'Enable Protected Mode' under the security Tab of 'IE Option' is either checked or unchecked across all zones.

可以 HTML 格式查看 TestNG 结果以进行详细分析。
