Automating Form Filling Using Selenium and Python
🤖 Automating Form Filling Using Selenium and Python (English)
Selenium is a powerful tool for automating web browsers. With Python, you can use Selenium to automatically fill out and submit forms on websites—useful for testing, data entry, scraping, and automation tasks.
✅ 1. Setup: Install Selenium
bash
Copy
Edit
pip install selenium
Also, download a WebDriver for your browser (e.g., ChromeDriver for Chrome):
👉 https://chromedriver.chromium.org/downloads
Place the driver in your system PATH or in your project folder.
🧱 2. Basic Form Automation Example
Suppose you want to fill out a simple form with name, email, and message.
🧪 Example Form HTML
html
Copy
Edit
<form id="contact-form">
<input type="text" name="name" />
<input type="email" name="email" />
<textarea name="message"></textarea>
<button type="submit">Send</button>
</form>
🐍 Python Code Using Selenium
python
Copy
Edit
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
import time
# Set up the browser (Chrome in this case)
driver = webdriver.Chrome()
# Go to the form page
driver.get("https://example.com/contact")
# Fill in the fields
driver.find_element(By.NAME, "name").send_keys("John Doe")
driver.find_element(By.NAME, "email").send_keys("john@example.com")
driver.find_element(By.NAME, "message").send_keys("Hello, this is a test message.")
# Optionally wait or scroll
time.sleep(1)
# Submit the form
driver.find_element(By.XPATH, "//button[@type='submit']").click()
# Wait and close browser
time.sleep(3)
driver.quit()
🧠 3. Common Ways to Locate Elements
Locator Method Example
By.ID By.ID, "username"
By.NAME By.NAME, "email"
By.CLASS_NAME By.CLASS_NAME, "form-input"
By.TAG_NAME By.TAG_NAME, "input"
By.XPATH By.XPATH, "//input[@name='name']"
By.CSS_SELECTOR By.CSS_SELECTOR, "input[name='email']"
⚠️ 4. Tips for Reliable Automation
Use time.sleep() or WebDriverWait to wait for elements to load.
Always handle exceptions using try/except to catch issues like missing elements.
Headless mode (for running without a UI):
python
Copy
Edit
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
driver = webdriver.Chrome(options=options)
🔐 5. Security Note
Don’t use Selenium to automate login or fill secure forms (like banking or CAPTCHAs) unless it's for testing your own application.
🧪 Optional: Wait for Elements
Use explicit waits for better reliability than time.sleep():
python
Copy
Edit
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 10)
name_input = wait.until(EC.presence_of_element_located((By.NAME, "name")))
🏁 Summary
Step Description
Install Selenium pip install selenium
Set up driver ChromeDriver/FirefoxDriver
Locate fields Use By.NAME, By.ID, By.XPATH, etc.
Fill and submit send_keys(), .click()
Wait & cleanup time.sleep() or WebDriverWait + driver.quit()
