我正在尝试点击 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();
    }

}

这是我定位 web 元素的对象类

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']")); …
