从上下文单击选择菜单

Question

我在自动右键单击然后从中选择任何选项时遇到问题。

代码在Firefox中正常运行，但在Chrome中运行良好。

在那里，它似乎只是显示右键，但正常点击该元素。

我正在使用chromedriver 2.21和Selenium 2.50。

package mentor.qa.selenium;

import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Stack {
    public static void main(String[] args) throws InterruptedException {

        System.setProperty("webdriver.chrome.driver", "C:\\Selenium\\chromedriver.exe");

        // WebDriver driver = new FirefoxDriver();
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.google.com/");

        WebDriverWait wait = new WebDriverWait(driver, 30);
        Thread.sleep(3000);

        WebElement b = driver.findElement(By.linkText("About"));
        Actions action = new Actions(driver);
        action.moveToElement(b);
        Thread.sleep(4000);

        // Keys move = Keys.ARROW_DOWN;
        // action.contextClick(b).sendKeys(move).sendKeys(Keys.ENTER).build().perform();

        action.contextClick(b).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).build().perform();
        Thread.sleep(4000);

        action.click().build().perform();
        // action.keyDown(Keys.CONTROL).click().build().perform();
        // action.contextClick(b).sendKeys(Keys.CONTROL).keyDown(Keys.CONTROL).sendKeys(String.valueOf(d)).sendKeys(Keys.ENTER).build().perform();
        // action.click();
        // action.contextClick(b);
        Thread.sleep(4000);

        // action.sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();
        // driver.findElement(By.partialLinkText("new tab")).click();
        // action.sendKeys(Keys.RETURN).perform();
        Thread.sleep(4000);

        //driver.quit();
    }
}
