 How to Perform Testing in selenium-

1. First import web driver in selenium.

1. We have multiple browsers so we can download its extension and use it.

1. driver. get method will navigate to a page, For whatever application you want to test, enter the URL of that application.

1. To access the HTML code, utilise the.page_source attribute.

1. Selenium Python follows different locating strategies for elements (ID, NAME, CLASS)

Command line - 

We are using this command line to perform selenium testing

• from selenium import webdriver
• from selenium.webdriver.common.by import By
• from selenium.webdriver.common.keys import Keys
• from selenium.webdriver.support.ui import WebDriverWait
• from selenium.webdriver.support.expected_conditions import presence_of_element_located

send_keys()-Inserts data into the input field through send_keys.

Click()-click is used to click any button

Locating Strategies - Locators Strategies are methods used to locate elements from the page and perform an operation on the same and attribute value matching the location will be returned. Selenium Python uses a variety of element finding techniques.

1. find_element_by_id

1. find_element_by_name

1. find_element_by_class

1. find_element_by_link_text

1. find_element_by_partial_link_text

Create a project and go to the python file and add the following code:
