These days most of the web apps are using AJAX techniques. When a page is loaded by the browser, the elements within that page may load at different time intervals. This makes locating elements difficult: if an element is not yet present in the DOM, a locate function will raise an ElementNotVisibleException exception. Using waits, we can solve this issue. Waiting provides some slack between actions performed - mostly locating an element or any other operation with the element.

Selenium Webdriver provides two types of waits - implicit & explicit. An explicit wait makes WebDriver wait for a certain condition to occur before proceeding further with execution. An implicit wait makes WebDriver poll the DOM for a certain amount of time when trying to locate an element.

5.1. Explicit Waits

An explicit wait is a code you define to wait for a certain condition to occur before proceeding further in the code. The extreme case of this is time.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = Platform Wns White Patent Puma Peacoat Basket webdriver.Firefox()
driverBasket Wns White Platform Peacoat Puma Patent .get("http://somedomain/url_that_delays_loading")
White Wns Patent Basket Platform Peacoat Puma try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"Puma Basket Platform Peacoat Patent Wns White ))
    )
finally:Bisgaard Jiar Bisgaard Bisgaard Jiar Green Green Green Bisgaard Jiar pqvwqT
    driver.quit()

This waits up to 10 seconds before throwing a TimeoutException unless it finds the element to return within 10 seconds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A successful return is for ExpectedCondition type is Boolean return true or not null return value for all other ExpectedCondition types.

Expected Conditions

There are some common conditions that are frequently of use when automating web browsers. Listed below are the names of each.

The expected_conditions module contains a set of predefined conditions to use with WebDriverWait.

Custom Wait Conditions

You can also create custom wait conditions when none of the previous convenience methods fit your requirements. A custom wait condition can be created using a class with __call__ method which returns False when the condition doesn’t match.

class element_has_css_class(Wns White Patent Peacoat Puma Basket Platform object):
  """An expectation for checking that an element has a particular css class.

  locator - used to find the element
  returns the WebElement once it has the particular css class
  """

    else:
        return False

element = wait.until(element_has_css_class((By.ID, 'myNewInput'), "myCSSClass"))

5.2. Implicit Waits

White Patent Peacoat Platform Puma Basket Wns An implicit wait tells WebDriver to poll the DOM for a certain amount of time when trying to find any element (or elements) not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object.
