Selenium and Webdriver waits

Here, I have listed all waits methods which is used in selenium web driver. It's helpful to eliminate  the random failures from your test suites.

Implicit waits

Selenium execution will wait for a specified time period to load the DOM elements.After that it will check the presence of web elements in the DOM, if not then throw errors. 

 Example: driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS)

Explicit waits:

Selenium execution will wait for a specified time period to load the locator and it will check the condition every 500ms.

Wait  wait = new WebDriverWait(driver, 30);

WebElement element= wait.until(visibilityOfElementLocated(By.id(“locator")));

Web driver waits 

There is a default web driver waits to check the presence, visibility, clickable and invisible and it will check the condition every 500ms.

Wait  wait = new WebDriverWait(driver, 20);

wait.until(ExpectedConditions.invisibilityOfElementLocated(locator));

wait.until(ExpectedConditions.presenceOfElementLocated(locator));

wait.until(ExpectedConditions.elementToBeClickable(locator));

wait.until(ExpectedConditions.visibilityOfElementLocated(locator));

Fluent wait:

If you want to check the presence of the web element in a specific time interval for maximum limit.

  For Example: it waits until the element with id “100" is found. If the element is not found, retry every 5 seconds. But wait only up to a maximum of 60 seconds.

Wait wait = new FluentWait(driver) .withTimeout(60, SECONDS) .pollingEvery(5, SECONDS) .ignoring(NoSuchElementException.class); WebElement foo = wait.until(new Function() { public WebElement apply(WebDriver driver) { return driver.findElement(By.id("id100")); }

Wait for Ajax calls in capybara. This will helpful to wait until all ajax calls completion.

def wait_for_ajax count = Capybara.default_wait_time * 10 actual_count = 0 count.times do break if page.evaluate_script 'window._ajax_sent == window._ajax_completed' actual_count += 1 sleep 0.1 end fail 'wait_for_ajax timed out! Please check for javascript errors in the context of the test!' if actual_count>= count end
