预期条件失败：正在等待By.xpath定位的元素的可见性

我试图单击alibaba.com网站上的“登录”链接

这是我的测试用例：

public class TestCase {
    public static void main(String[] args) throws InterruptedException {
        // TODO Auto-generated method stub
        String URL = "http://www.alibaba.com/";
        WebDriver driver;
        System.setProperty("webdriver.chrome.driver",
                "D:\\chromedriver_win32\\chromedriver.exe");
        driver = new ChromeDriver();
        driver.get(URL);
        Thread.sleep(2000);
        SignIn.SignIn_click(driver).click();
    }
}

这是定位Web元素的对象类

package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class SignIn {
    private static WebElement element = null;
    public static WebElement SignIn_click(WebDriver driver) {
        element = (new WebDriverWait(driver, 10)).until(ExpectedConditions
                .visibilityOfElementLocated(By
                        .xpath("//a[@data-val='ma_signin']")));
        element = driver.findElement(By
                .xpath("//a[@data-val='ma_signin']"));
        return element;
    }
}

但是，当我运行此代码时，总是会遇到以下异常：

Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: //a[@data-val='ma_signin'] (tried for 10 second(s) with 500 MILLISECONDS interval)

请帮我。

回答：

请尝试以下操作：

package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class SignIn {
    private static WebElement element = null;
    public static WebElement SignIn_click(WebDriver driver) throws InterruptedException {
    element = driver.findElement(By.xpath("id('J_SC_header')/header/div[2]//span[1]/a[@data-val='ma_signin']"));
    while (!isDisplayed(element)) 
    {
        Thread.sleep(3000);
        System.out.println("Element is not visible yet");
    }
    return element;
    }
    public static boolean isDisplayed(WebElement element) {
        try {
            if(element.isDisplayed())
                return element.isDisplayed();
            }catch (NoSuchElementException ex) {
            return false;
        }
        return false;
    }
}
