java - moveToElement()执行悬停操作

有人可以帮助显示为什么这不起作用吗？

页面对象：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.support.CacheLookup;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.How;
import org.openqa.selenium.support.PageFactory;

    public class NavBarPO {

    WebDriver driver;
    Actions action;

    public NavBarPO(WebDriver driver){
        this.driver = driver;
        PageFactory.initElements(driver, this);
        action = new Actions(driver);
    }
        @CacheLookup
        @FindBy(how = How.CSS, using = "li.menu-item.menu-item-type-taxonomy.menu-item-object-wpsc_product_category.menu-item-has-children.has_children > a")
        private WebElement product_Category;

        public void hover_Product_Category(){
            action.moveToElement(product_Category);
        }
}

测试：

public class OpenDemos {

        @BeforeTest
        public void Initialize() {
            System.setProperty("webdriver.chrome.driver", "C:/Users/u6028938/Documents/Selenium Java/chromedriver.exe");
            System.setProperty("webdriver.gecko.driver", "C:/Users/u6028938/Documents/Selenium Java/geckodriver.exe");
        }

        @Test
          public void SecondTest() throws InterruptedException {
              WebDriver driver = new FirefoxDriver();
              NavBarPO nav = new NavBarPO(driver);
              driver.get("http://www.store.demoqa.com");
              Thread.sleep(3000);
              nav.Hover_Product_Category();
              System.out.println("Successfully Executed Test!");
              Thread.sleep(10000);
              driver.quit();
          }
    }

nav.hover_Product_Category()只是什么都不做，甚至没有错误。当我使用.click()而不是.moveToElement()时，单击元素并显示我想要的下拉列表，因此选择器正确。

最佳答案

您需要在perform()类方法上调用Actions

public void hover_Product_Category(){
    action.moveToElement(product_Category).perform();
}
