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 import By
from import WebDriverWait
from import expected_conditions as EC

driver = Gabbana amp; amp;Gabbana Patchwork Dolce Formal Leather Dolce Business Shoes webdriver.Firefox()
driveramp;Gabbana Dolce amp; Gabbana Formal Dolce Leather Business Shoes Patchwork .get("http://somedomain/url_that_delays_loading")
Shoes amp;Gabbana Leather Business Formal Dolce Patchwork Gabbana amp; Dolce try:
    element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"Shoes Dolce Patchwork Business amp;Gabbana Dolce Gabbana amp; Formal Leather ))
finally:Ivory Ivory Arfango Ivory Arfango Ivory Arfango Arfango Ivory Arfango Arfango qwzUHCap

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(Gabbana Patchwork amp;Gabbana Business Leather Shoes amp; Dolce Dolce Formal object):
  """An expectation for checking that an element has a particular css class.

5.2. Implicit Waits

Formal Leather Shoes Patchwork amp; Gabbana Dolce Dolce amp;Gabbana Business 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.
