public void Resize(IWebElement element, int offsetX, int offsetY = 0)
{   
    int width = element.Size.Width;            
    Actions action = new Actions(driver);
    action.MoveToElement(element, width, 1);
    action.ClickAndHold().MoveByOffset(offsetX, offsetY).Release();
    action.Build().Perform();            
}

您可以在css中设置高度和宽度，然后使用

getCssValue(java.lang.String propertyName)

有关更多详细信息，请参见http://selenium.googlecode.com/svn/trunk/docs/api/java/org/openqa/selenium/WebElement.html。我找不到任何示例代码，对不起！

我还必须使用Selify来调整\dragAndDrop的大小。所以在一些研究之后，我找到了this site，它告诉你如何在没有Js的情况下调整大小：

WebElement resizeable = this.getDriver().findElement(By.cssSelector(" enter your selector, mine was div.resize"));

Action resize = action.clickAndHold(resizeable).moveByOffset(X offset, Y offset).release().build();

resize.perform();

我试过了，它起作用了。至于拖动，您可以使用：

Actions builder = new Actions(driver);

Action dragAndDrop = builder.clickAndHold(someElement)
   .moveToElement(otherElement)
   .release(otherElement)
   .build();

dragAndDrop.perform();

我已经为其中一个网站做了调整代码。

        System.setProperty("webdriver.chrome.driver", "C:\\Users\\aadityn\\Downloads\\chromedriver_win32\\chromedriver.exe");
        driver= new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://demoqa.com/resizable");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        TC025_Interactions_Resizable tt=new TC025_Interactions_Resizable();

        //scroll down to the desired element
        tt.Scroll();

        //clicking on tabs 
        WebElement resizeableElement = driver.findElement(By.xpath("//div[@id='resizableBoxWithRestriction']/span"));
        resizable(resizeableElement, 200, 100);

        Thread.sleep(2000L);

        //closing the session
    //  driver.quit();

    }

    public static void resizable(WebElement elementToResize, int xOffset, int yOffset) 
    {
                try
                {
                    Actions act= new Actions(driver);
                    act.clickAndHold(elementToResize).moveByOffset(xOffset, yOffset).release().build().perform();
                }
                catch (StaleElementReferenceException e)

                } 
                catch (Exception e) 
                {
                        System.out.println("Unable to resize" + elementToResize + " - " + e.getStackTrace());
                }

    }

    public void Scroll()
    {
        JavascriptExecutor jse= (JavascriptExecutor)driver;
        jse.executeScript("window.scrollBy(0,300)", "");
    }
}

我发现了以下几点：

• 在Selify中拖放工作正常
• selenium 中元素没有调整大小的方法
• 如果一个元素是可调整大小的，在我的例子中是一个框架，那么在HTML站点中有一个元素可以调整大小(该元素可能是不可见的，但如果你移动到它上面，鼠标光标就会改变)
• 您只需识别此元素并在其上执行拖放操作
