Selenium Actions.movetoElement - org.openqa.selenium.UnsupportedCommandException

问题

I have a scenario where I have to hover over a menu link and click on the drop down sub menus. The code that I'm using is below:

public void changeLanguageTest() throws InterruptedException
    {
        WebElement LanguageMenu = driver.findElement(By.cssSelector(".change-language>button"));
        action.moveToElement(LanguageMenu);
        WebElement mongolianLang = driver.findElement(By.cssSelector(".change-language>ol>li:nth-child(3)>a"));
        action.moveToElement(mongolianLang).click().build().perform();
        Thread.sleep(3000L);
    }

But when I run this code, It fails with an error message :-

org.openqa.selenium.UnsupportedCommandException: POST /session/3077f893-d9ab-487d-b09f-c5bcd135ea31/moveto did not match a known command

I tried below mentioned code too but no success and same error occurred.

BaseClass.action.moveToElement(LanguageMenu).moveToElement(mongolianLang).click().build().perform();

I'm using webdriver v2.53 and running it on FF v47.0.1.

As a bug logged here geckodriver does not yet implement actions. The actions we will implement are those being defined right now in the W3C WebDriver standard and not those of Selenium.

Selenium has said they will provide a Selenium-to-W3C-WebDriver shim for actions, but this may take some time to produce after we have made our implementation. Implementation in geckodriver/Marionette has not yet started.

As mentioned here from v0.12.0 of geckodriver, Implemented routing for new actions API, but it too is not yet fully implemented in Marionette

You should upgrade your geckodriver.
