@Test
/**
 * Function to perform a scroll down for the page with a time delay of 50ms
 * window.scrollBy(0,500) - Horizontal and vertical scroll increments
 * setTimeout('pageScroll()',50) - scrolls every 50 milliseconds

public void pageScroll() {
    driver.get("http://someURl.com");
    // invoke javascript executor
    JavascriptExecutor executor = (JavascriptExecutor) driver;
    executor.executeScript("window.scrollBy(0,500);scrolldelay = setTimeout('pageScroll()',50);");
}
