Install

pip install selenium

Usage

Follow the instructions in Getting Started.

Note: For setting up the test driver for the class, see Setup

Sample

From http://pypi.python.org/pypi/selenium:

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
import time

browser = webdriver.Firefox() # Get local session of firefox
browser.get("http://www.yahoo.com") # Load page
assert "Yahoo!" in browser.title
elem = browser.find_element_by_name("p") # Find the query box
elem.send_keys("seleniumhq" + Keys.RETURN)
time.sleep(0.2) # Let the page load, will be added to the API
try:
    browser.find_element_by_xpath("//a[contains(@href,'http://seleniumhq.org')]")
except NoSuchElementException:
    assert 0, "can't find seleniumhq"
browser.close()

Chrome

To use the webdriver for Chrome:

Change the code from webdriver.Firefox() to webdriver.Chrome().
Download ChromeDriver server for linux from http://code.google.com/p/selenium/downloads/list (I downloaded chromedriver_linux64_13.0.775.0.zip).
Extract the contents of the archive to a folder on your PATH. I copied chromedriver to ~/bin/
Run your tests.

Issues

If you get the following error, it is probably because you are using remote control (RC) and the Selenium Server is not installed and running:

error: [Errno 111] Connection refused

To solve this issue, use Selenium 2 i.e. webdriver.Firefox (see sample above). You don’t need Selenium Server when using version 2.
