这是我尝试运行脚本时显示的错误消息？场景：我的一个java文件具有登录功能，第二个在登录后创建了一个新帐户请建议。

Login.java：

public class LoginPage 
{ 

    public static WebDriver driver;  

    public static final LoginPage login = new LoginPage(new FirefoxDriver()); 

    public LoginPage(WebDriver driver) 
    {    
        LoginPage.driver = driver;  
    } 

    public static void loginAs(String username, String password) 
    {  
        DesiredCapabilities ieCapabilities = DesiredCapabilities.firefox();

        ieCapabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true); 

        Proxy proxy = new Proxy(); 

        proxy.setProxyAutoconfigUrl("http://www.config.barclays.co.uk:9000/");

        driver.close();

        ieCapabilities. setCapability(CapabilityType.PROXY, proxy); 

        FirefoxDriver driver = new FirefoxDriver(ieCapabilities);

        driver.get("https://login.salesforce.com"); 

        driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS);

        //Login to Salesforce Application
        try
        {
            driver.findElement(By.id("username")).sendKeys(username);

            driver.findElement(By.id("password")).sendKeys(password);   

            driver.findElement(By.id("Login")).click();

            driver.manage().timeouts().implicitlyWait(75, TimeUnit.SECONDS);

        }
        catch(Exception e1)
        {

            System.out.println(e1 +"Your login attempt has failed. The username or password may be incorrect, or your location or login time may be restricted. Please contact the administrator at your company for help.");
        }

    }


    public static void main(String[] args)
    {
        login.loginAs("me@example.com", "Pa$$word"); 
    }
}

我试图点击Salesforce应用程序的Opportunity选项卡的第二个文件： CreatOpportunity.java这些行在我的主要参数

下

LoginPage.login.loginAs("username", "password");

LoginPage.login.driver.findElement(By.id("Opportunity_Tab")).click();

运行我的第二个文件允许我启动我的应用程序，但是没有检测到Opprtunity选项卡上的点击并且抛出了上面提到的错误

Answer 1

登录后放下线即可试一试。

driver.switchTo.defaultContent();

尝试以下代码。

public class LoginPage {
    public static WebDriver driver;  

    public LoginPage() 
    {    
         DesiredCapabilities ieCapabilities = DesiredCapabilities.firefox();
         ieCapabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true); 
         Proxy proxy = new Proxy(); 
         proxy.setProxyAutoconfigUrl("http://www.config.barclays.co.uk:9000/");
         ieCapabilities. setCapability(CapabilityType.PROXY, proxy); 
         LoginPage.driver = new FirefoxDriver(ieCapabilities); 
         driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS);
    } 

    public static void loginAs(String username, String password) {  



        driver.get("https://login.salesforce.com"); 
        //Login to Salesforce Application
        try
            { 
            driver.findElement(By.id("username")).sendKeys(username);
            driver.findElement(By.id("password")).sendKeys(password);   
            driver.findElement(By.id("Login")).click();
            driver.manage().timeouts().implicitlyWait(75, TimeUnit.SECONDS);
            }
        catch(Exception e1) {

            System.out.println(e1 +"Your login attempt has failed. The username or password may be incorrect, or your location or login time may be restricted. Please contact the administrator at your company for help.");
        }
}

    public static void main(String[] args)
    {
        LoginPage login = new LoginPage(); 
        login.loginAs("me@example.com", "Pa$$word"); 
        FileTwo.clickOpportunity(driver);
    }

}

FileTwo传送

public class FileTwo
{
 public static void clickOpportunity(WebDriver driver)
 throws Exception
 {
      driver.findElement(By.id("Opportunity_Tab")).click();
 }
}

Answer 2

如果你调用quit（）方法，那么Selenium就会抛出这个错误。尝试再次启动浏览器。解决方法是使用close（）方法而不是quit（）

Selenium webdriver脚本中的UnreachableBrowserException
