Selenium自動元素點擊返回null

Question

我已經在硒中編寫了一個自動化測試用例來測試登錄頁面，並且應該點擊忘記密碼link.Browser打開並轉到給定的URL但忘記了密碼鏈接不會自動點擊，有人可以告訴我的代碼有什麼問題。

BaseCode

public class Forgetpsw { 

    WebDriver driver; 

    @BeforeTest 
    public void Browseropen() throws Exception { 
     Browsers startup=new Browsers(); 
     startup.Initiating(); 
    } 

    @Test 
    public void Forget(String username) throws Exception{ 
     driver.findElement(By.xpath("//*[text()='Forgot Password?']")).click(); 
     Thread.sleep(3000L); 
     driver.findElement(By.xpath("//*[@placeholder='User ID'][@id='forgotPasswordForm:j_idt13:0:username']")).sendKeys(username); 
    } 
} 

Browsers.java

public class Browsers { 
    public WebDriver driver; 

    public void Initiating() throws IOException { 
     Properties prop= new Properties(); 
     InputStream fis = new FileInputStream("D:\\Workspace\\TMS\\selenium\\ZLive\\src\\datadriven.properties"); 
     prop.load(fis); 


     System.out.println("Initiating Browser"); 

     if (prop.getProperty("browser").equals("firefox")) 
     { 
      driver=new FirefoxDriver(); 
     } 
     else 
     { 
      System.setProperty("webdriver.chrome.driver", "D:\\selenium\\chromedriver_win32\\chromedriver.exe"); 
      driver = new ChromeDriver(); 
     } 
     driver.manage().window().maximize(); 
     driver.get(prop.getProperty("url")); 
    } 
} 

data.properties

browser=firefox 
url=http://abcd.xxx.in/login 
username=32131 
pasword=32131

Answer 1

裏面你Initiating方法，你需要返回驅動程序對象並將其存儲在您的Forgetpsw類。

public void Initiating() throws IOException { 
    Properties prop= new Properties(); 
    InputStream fis = new FileInputStream("D:\\Workspace\\TMS\\selenium\\ZLive\\src\\datadriven.properties"); 
    prop.load(fis); 


    System.out.println("Initiating Browser"); 

    if (prop.getProperty("browser").equals("firefox")) 
    { 
     driver=new FirefoxDriver(); 
    } 
    else 
    { 
     System.setProperty("webdriver.chrome.driver", "D:\\selenium\\chromedriver_win32\\chromedriver.exe"); 
     driver = new ChromeDriver(); 
    } 
    driver.manage().window().maximize(); 
    driver.get(prop.getProperty("url")); 
    return driver; //return the driver object. 
} 

而且Browseropen方法是什麼樣子，

public void Browseropen() throws Exception { 
    Browsers startup=new Browsers(); 
    driver = startup.Initiating(); 
    } 

Answer 2

在您的起爆（）方法，我只好返回，如驅動程序。

public WebDriver Initiating() throws IOException { 
    //your code 
    return driver 
} 

，並使用這

@BeforeTest 
public void Browseropen() throws Exception { 
    Browsers startup=new Browsers(); 
    this.driver = startup.Initiating(); //your declared driver will get the initialized driver. 
} 

希望這會幫助你返回驅動程序。
