How to wait until an element is present in Selenium

Question

I m trying to make Selenium wait for an element that is dynamically added to the DOM after page load  Tried this   fluentWait until ExpectedConditions presenceOfElement By id  elementId       In case it helps  here is fluentWait   FluentWait fluentWait   new FluentWait lt  gt  webDriver         withTimeout 30  TimeUnit SECONDS       pollingEvery 200  TimeUnit MILLISECONDS       But it throws a NoSuchElementException - looks like presenceOfElement expects the element to be there so this is flawed  This must be bread and butter to Selenium and don t want to reinvent the wheel    could anyone suggest an alternative  ideally without rolling my own Predicate

FluentWait throws a NoSuchElementException is case of the confusion

org.openqa.selenium.NoSuchElementException;

with

java.util.NoSuchElementException

in

.ignoring(NoSuchElementException.class)

You need to call ignoring with exception to ignore while the WebDriver will wait    FluentWait lt WebDriver gt  fluentWait   new FluentWait lt  gt  driver           withTimeout 30  TimeUnit SECONDS           pollingEvery 200  TimeUnit MILLISECONDS           ignoring NoSuchElementException class     See the documentation of FluentWait for more info  But beware that this condition is already implemented in ExpectedConditions so you should use  WebElement element    new WebDriverWait driver  10       until ExpectedConditions elementToBeClickable By id  someid         Update for newer versions of Selenium   withTimeout long  TimeUnit  has become withTimeout Duration  pollingEvery long  TimeUnit  has become pollingEvery Duration    So the code will look as such   FluentWait lt WebDriver gt  fluentWait   new FluentWait lt  gt  driver           withTimeout Duration ofSeconds 30           pollingEvery Duration ofMillis 200           ignoring NoSuchElementException class     Basic tutorial for waiting can be found here

Let me recommend you using Selenide library   It allows writing much more concise and readable tests  It can wait for presence of elements with much shorter syntax       elementId   shouldBe visible     Here is a sample project for testing Google search  https   github com selenide-examples google
