如何通过 Java 使用 Selenium 调整元素的大小？

Question

我正在尝试通过链接 - http://jqueryui.com/resizable/自动化 Selenium 中的“可实现概念”（拖放）。我收到错误消息：invalid selector: Unable to locate an element with the xpath expression //div[contains(@class.'demo-frame')].您能否让我知道是否有任何其他方式来表示 XPATH？下面是我的代码。提前致谢。public class ResizeExample {    WebDriver driver;    @Test    public void testToResizeElement() {        driver = new FirefoxDriver();        driver.manage().window().maximize();        driver.navigate().to("http://jqueryui.com/resizable/");        WebDriverWait wait = new WebDriverWait(driver, 5);        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector(".demo-frame")));        WebElement resizeableElement = driver.findElement(By.cssSelector(".ui-resizable-handle.ui-resizable-se.ui-icon.ui-icon-gripsmall-diagonal-se"));        resize(resizeableElement, 50, 50);    }    public void resize(WebElement elementToResize, int xOffset, int yOffset) {        try {            if (elementToResize.isDisplayed()) {                Actions action = new Actions(driver);                action.clickAndHold(elementToResize).moveByOffset(xOffset, yOffset).release().build().perform();            } else {                System.out.println("Element was not displayed to drag");            }        } catch (StaleElementReferenceException e) {            System.out.println("Element with " + elementToResize + "is not attached to the page document "  + e.getStackTrace());        } catch (NoSuchElementException e) {            System.out.println("Element " + elementToResize + " was not found in DOM " + e.getStackTrace());        } catch (Exception e) {            System.out.println("Unable to resize" + elementToResize + " - " + e.getStackTrace());        }    }}

要通过Selenium在网页http://jqueryui.com/resizable/中自动实现可实现的概念（拖放） ，您可以使用以下解决方案：

代码块：

System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");

WebDriver driver=new FirefoxDriver();

driver.get("http://jqueryui.com/resizable/");

driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@class='demo-frame']")));

WebElement  target = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//div[@class='ui-resizable-handle ui-resizable-se ui-icon ui-icon-gripsmall-diagonal-se']")));

//dragAndDropBy(WebElement source, int xOffset, int yOffset) //status: WORKS

new Actions(driver).dragAndDropBy(target, 50, 50).build().perform();

System.out.println("Resizing of element Completed");

控制台输出：

Resizing of element Completed
