“属性值未定义为注释类型参数”错误显示为跨浏览器测试脚本

Question

我正在尝试使用Selenium进行此跨浏览器测试。

CrossBrowser.java：

package automationFramewok; 

import java.net.MalformedURLException; 

import org.openqa.selenium.chrome.ChromeDriver; 
import org.openqa.selenium.firefox.FirefoxDriver; 

import org.openqa.selenium.opera.OperaDriver; 

import org.openqa.selenium.remote.DesiredCapabilities; 

import org.testng.annotations.BeforeTest; 
import org.testng.annotations.Test; 

import com.beust.jcommander.Parameters; 

// I am getting the following error on the next line 
// 
// "The attribute value is undefined for the annotation type Parameters" 
// 
@Parameters({"browser"}) 

public class CrossBrowser { 

    @SuppressWarnings("deprecation") 
    @BeforeTest 

    public void setUp(String browser) throws MalformedURLException { 

    if (browser.equalsIgnoreCase("Firefox")) { 
     System.out.println("Running Firefox"); 
     System.setProperty("webdriver.gecko.driver","E:\\\\Selenium-required files\\geckodriver\\geckodriver.exe"); 
     FirefoxDriver driver = new FirefoxDriver(); 
    } else if (browser.equalsIgnoreCase("chrome")) { 
     System.out.println("Running Chrome"); 
    System.setProperty("webdriver.chrome.driver", "E:\\\\\\\\Selenium-required files\\\\chromedriver\\\\chromedriver.exe"); 
     ChromeDriver driver = new ChromeDriver(); 
    } else if (browser.equalsIgnoreCase("opera")) { 
     System.out.println("Running Opera"); 
    // driver = new OperaDriver();  --Use this if the location is set properly-- 
     DesiredCapabilities capabilities = new DesiredCapabilities(); 
    capabilities.setCapability("opera.binary", "C://Program Files (x86)//Opera//opera.exe"); 
     capabilities.setCapability("opera.log.level", "CONFIG"); 
     System.setProperty("webdriver.opera.driver", "E:\\\\\\\\Selenium-required files\\\\operadriver\\\\operadriver.exe"); 
     OperaDriver driver = new OperaDriver(capabilities); 
    } 
    } 
} 

我收到以下错误信息：

的属性值是未定义注释类型参数

我怎样才能解决这个问题？

查看您的进口报表清单。我想你想

import org.testng.annotations.Parameters; 

，而不是

import com.beust.jcommander.Parameters;
