Question

我有一个包含可重用方法的密钥类。我试图在两种方法中使用WebElement。他们的关心紧密相连。我知道这是我们失败的因素，因为我可以在不使用两种方法的情况下对其进行编码而且工作正常。当调用包含webelement的方法时，如何在没有失败的情况下正确执行此操作？（没有这样的元素例外）

公共类密钥{

WebElement webElement = null;

public void hoover(String path) throws InterruptedException{

    webElement= driver.findElement(By.xpath(path));
    Actions act = new Actions(driver);
    act.moveToElement(webElement).perform();
    Thread.sleep(5000); 
}


public void click(String path) throws InterruptedException{

    webElement = driver.findElement(By.xpath(path));
    webElement.click();//This opens menu list
    Thread.sleep(5000);
}

另一个类使用如下：

    session.navigate("url");
session.hoover("someTab");
Assert.assertTrue(session.isElementPresent("otherSub"), "Element not present");
session.click("otherSub");

Answer 1

问题可能在于您不等待元素可见。这可能是因为您在可用之前（在将其加载到页面之前）请求它。 Selenium充当用户，因此您需要告诉它等待元素可见然后获取它，而不是立即获取它

public void clickElementWhenReady(By locator, int timeout) {
    WebDriverWait wait = new WebDriverWait(driver, timeout);
    WebElement element = wait.until(ExpectedConditions.elementToBeClickable(locator));
    element.click();
}

你可以实现类似的东西，以便在一段时间内为元素汇集并在之后抛出错误

Answer 2

缺少OR.getProperty（）

webElement = driver.findElement(By.xpath(OR.getProperty(path)));
webElement.click();//This opens menu list
Thread.sleep(5000);

调用时，两种方法中的Selenium Webelement失败
