Answer 1

我通过这种方式解决了它:

// Create instance of Javascript executor
JavascriptExecutor je = (JavascriptExecutor) driver;
//Identify the WebElement which will appear after scrolling down
WebElement element = driver.findElement(By.tagName("...."));
// now execute query which actually will scroll until that element is not appeared on page.
je.executeScript("arguments[0].scrollIntoView(true);",element);
