Selenium Webdriver code example

Example 1: chromedriver selenium python

# For Linux, but it is similar for Windows
# First make sure first that you have chrome browser installed on your system.

# a simple way to get the driver is: 
sudo apt-get install chromium-chromedriver
# this will download 75MB of files.

# another way is:
1. Download the lastest version of driver from:
  https://sites.google.com/a/chromium.org/chromedriver/ # only 5-7MB
2. Unzip the file.
3. Paste the file in /usr/local/bin using this command:
  sudo mv chromedriver /usr/local/bin # this makes sure that the directory is in your PATH variable.
4. Make your file executable:
  sudo chmod +x /usr/local/bin/chromedriver

Now you can use this in python:
  >>from selenium import webdriver
  >>browser = webdriver.Chrome()
  # it will work fine

Example 2: selenium webdriver python

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()
