WebDriver Wait Commands

Wait commands in WebDriver

Listing out the different WebDriver Wait statements that can be useful for an effective scripting and can avoid using the Thread.sleep() comamnds

After few searches and digging into the WebDriver Java doc, I managed to design a mindmap of the different WebDriver commands available

webdriver mindmap

WebDriver.manage().timeouts()

implicitlyWait

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("http://somedomain/url_that_delays_loading");
WebElement myDynamicElement = driver.findElement(By.id("myDynamicElement"));


The ImplicitWait will tell the webDriver to poll the DOM for a certain duration when trying to find the element, this will be useful when certain elements on the webpage will not be available immediately and needs some time to load.
By default it ill take the value to 0, for the life of the WebDriver object instance through out the test script.

pageLoadTimeout

driver.manage().timeouts().pageLoadTimeout(100, SECONDS);

Sets the amount of time to wait for a page load to complete before throwing an error. If the timeout is negative, page loads can be indefinite.

setScriptTimeout

driver.manage().timeouts().setScriptTimeout(100,SECONDS);

Sets the amount of time to wait for an asynchronous script to finish execution before throwing an error. If the timeout is negative, then the script will be allowed to run indefinitely.

FluentWait

// Waiting 30 seconds for an element to be present on the page, checking
   // for its presence once every 5 seconds.
   Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
       .withTimeout(30, SECONDS)
       .pollingEvery(5, SECONDS)
       .ignoring(NoSuchElementException.class);

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

Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page.

ExpectedConditions

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("someid")));

Models a condition that might reasonably be expected to eventually evaluate to something that is neither null nor false.
Examples : Would include determining if a web page has loaded or that an element is visible.
Note that it is expected that ExpectedConditions are idempotent. They will be called in a loop by the WebDriverWait and any modification of the state of the application under test may have unexpected side-effects.


WebDriverWait will be used as we used in the Expected conditions code snippet as above.


sleeper is something same as the Thread.sleep() method, but this with an Abstraction around the thread.sleep() for better testability

    I truly appreciate this post. I’ve been looking all over for this! Thank goodness I found it on Bing. You’ve made my day! Thanks again!

    Awesome post

  3. Hi!
    I would like to recommend you Selenide – a library providing much easier way to wait for events.

    With Selenide you just need to write one line:
    $(“#myDynamicElement”).shouldBe(visible);

    More examples in Wiki: https://github.com/codeborne/selenide/wiki/Selenide-vs-Selenium#5-ajax-support-waiting-for-some-event-to-happen

    How to wait till a new window is displayed.

    My scenario is like this

    I have 3 IE windows opened(not in tabs).
    In the third window I have a submit button.
    If I click that submit button a new window i.e 4th one opens.

    Right now I am using Thread.sleep() to wait after clicking submit button which is not a good practice.

    Is there a way to wait using WebDriver wait.

    Thanks in adavance
