Question

我使用java语言编写了一个selenium程序的代码。当我运行代码时遇到问题。我用过xpath＆amp;用于标识元素的linktext。程序代码也与youtube中的代码完全匹配。但仍然应用程序抛出如下错误消息。

我的代码：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class AdminInterface {
    public static WebDriver driver;
    public void launchApplication()
    {
        System.setProperty("webdriver.ie.driver", "C:\\Users\\rprem\\Downloads\\IEDriverServer_x64_3.4.0\\IEDriverServer.exe");
        driver = new InternetExplorerDriver();
        driver.get("http://www.gcrit.com/build3/admin/login.php?osCAdminID=es8t35f3gvo51onj3q1omnef00");
    }
    public void loginApplication(String Username, String Password) throws InterruptedException
    {
        driver.findElement(By.name("username")).sendKeys(Username);
        driver.findElement(By.name("password")).sendKeys(Password);
        driver.findElement(By.id("tdb1")).click();
        Thread.sleep(1000);
    }
    public void closeBrowser()
    {
        driver.close();
    }
public static void main(String[] args) throws InterruptedException 
    {
        AdminInterface obj = new AdminInterface();
obj.launchApplication();
        obj.loginApplication("admin", "admin@123");
        boolean Aol = driver.findElement(By.xpath(".//*[@id='adminAppMenu']/div[1]/ul/li[1]/a")).isDisplayed();
        Thread.sleep(1000);
        boolean Bol = driver.findElement(By.xpath(".//*[@id='adminAppMenu']/div[1]/ul/li[2]/a")).isDisplayed();
        Thread.sleep(1000);
        boolean Col = driver.findElement(By.xpath(".//*[@id='adminAppMenu']/div[1]/ul/li[3]/a")).isDisplayed();
        Thread.sleep(1000);
        if (Aol == true && Bol == true && Col == true)
        {
            System.out.println("TestCase 3: + All required links are present");
        }
        obj.closeBrowser();
    }
    }

以下是验证是否显示所有3个链接（即Categories/Products，Manufacturers和Reviews链接的示例代码块：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class Q45519546_find_element 
{

    public static WebDriver driver;
    public void launchApplication()
    {
    System.setProperty("webdriver.ie.driver", "C:\\Utility\\BrowserDrivers\\IEDriverServer.exe");
    driver = new InternetExplorerDriver();
    driver.get("http://www.gcrit.com/build3/admin/login.php?osCAdminID=es8t35f3gvo51onj3q1omnef00");
    }
    public void loginApplication(String Username, String Password) throws InterruptedException
    {
    driver.findElement(By.name("username")).sendKeys(Username);
    driver.findElement(By.name("password")).sendKeys(Password);
    driver.findElement(By.id("tdb1")).click();
    Thread.sleep(1000);
    }
    public void closeBrowser()
    {
    driver.close();
    }

    public static void main(String[] args) throws InterruptedException 
    {
    Q45519546_find_element obj = new Q45519546_find_element();
    obj.launchApplication();
    obj.loginApplication("admin", "admin@123");
    boolean Aol = driver.findElement(By.xpath("//div[@id='adminAppMenu']//a[contains(.,'Categories/Products')]")).isDisplayed();
    Thread.sleep(1000);
    boolean Bol = driver.findElement(By.xpath("//div[@id='adminAppMenu']//a[contains(.,'Manufacturers')]")).isDisplayed();
    Thread.sleep(1000);
    boolean Col = driver.findElement(By.xpath("//div[@id='adminAppMenu']//a[contains(.,'Reviews')]")).isDisplayed();
    Thread.sleep(1000);
    if (Aol == true && Bol == true && Col == true)
    {
        System.out.println("TestCase 3: + All required links are present");
    }
    obj.closeBrowser();
    }
}

如果这回答你的问题，请告诉我。
