implicitly-wait : 브라우져 전체 요소가 로드될 때 까지 기다린다.
explicitly-wait : 특정 요소가 로드될 때 까지 기다린다.

Fluent wait

Wait wait = new FluentWait(WebDriver reference)
.withTimeout(timeout, SECONDS)
.pollingEvery(timeout, SECONDS)
.ignoring(Exception.class);

WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
 public WebElement applyy(WebDriver driver) {
 return driver.findElement(By.id("foo"));
}});
