Selenium is a widely used tool for autoamting web browser interactions, enabling the creation of efficient testing frameworks. This guide covers setting up a basic framework using Python and Selenium.

Installation and Setup

Install Selenium using pip:

pip install selenium

Download and configure a browser driver, such as geckodriver for Firefox. Extract and move it to a directory in your system's PATH.

Basic Browser Operations

Create a Python script to perform common browser actions:

import time
from selenium import webdriver

# Initialize Firefox driver
browser = webdriver.Firefox()

# Navigate to a website
browser.get('https://www.example.com')

# Adjust window dimensions
browser.set_window_size(1024, 768)

# Wait for 2 seconds
time.sleep(2)

# Refresh the page
browser.refresh()

# Maximize the window
browser.maximize_window()

# Close the browser
browser.quit()

Element Interaction and Testing

Automate interactions with web elements, such as input fields and buttons:

import time
from selenium import webdriver

# Start browser session
driver = webdriver.Firefox()
driver.get('https://www.testforum.com/login')

# Wait for page load
time.sleep(3)

# Locate and fill username field using ID
username_field = driver.find_element_by_id('username_input')
username_field.send_keys('test_user')

# Locate and fill password field using ID
password_field = driver.find_element_by_id('password_input')
password_field.send_keys('secure_pass')

# Locate login button using XPath and click
login_button = driver.find_element_by_xpath('//button[@type="submit"]')
login_button.click()

# Retrieve and print button text
button_text = login_button.text
print(f'Button text: {button_text}')

# Get attribute value
type_attr = login_button.get_attribute('type')
print(f'Button type attribute: {type_attr}')

# Close the session
driver.quit()

This framework supports regression testing by automating repetitive tasks, reducing manual effort and improving test coevrage.
