Selenium testing without browser

I use Selenium RC for testing. Now to perform a load test, I want to run parallel test cases. Is there any way to run them without opening a browser?

To set up on Centos (do all installation as root)

Install pip Download https://bootstrap.pypa.io/get-pip.py

python get-pip.py

Installing selenium If you have pip on your system, you can simply install or upgrade the Python bindings:

pip install -U selenium

Alternately, you can download the source distribution from PyPI (e.g. selenium-2.53.1.tar.gz), unarchive it, and run:

python setup.py install

install the program: pyvirtualdisplay

pip install pyvirtualdisplay

yum install Xvfb libXfont Xorg

Then modify your script and get this.

from pyvirtualdisplay import Display
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import NoAlertPresentException
import unittest, time, re

class SeleniumDemo(unittest.TestCase):

    def setUp(self):
        self.display = Display(visible=0, size=(800, 600))
        self.display.start()
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://www.soastastore.com/"
        self.verificationErrors = []
        self.accept_next_alert = True


    def tearDown(self):
        self.driver.quit()
        self.display.stop()
        self.assertEqual([], self.verificationErrors)

You can simply pass an argument "headless" to test selenium without opening the browser.

op = webdriver.ChromeOptions()
op.add_argument('headless')
driver = webdriver.Chrome(options=op)

This code snippet will provide you exactly what you want.

requirements:

sudo apt-get install xvfb
pip install selenium
pip install PyVirtualDisplay

download chrome driver binary from below link and paste into drivers directory: https://sites.google.com/a/chromium.org/chromedriver/downloads

code:

from selenium import webdriver
from pyvirtualdisplay import Display

with Display(visible=False, size=(800, 600)):
    browser = webdriver.Chrome('drivers/chromedriver')
    browser.get('https://www.example.com')
    print(browser.page_source)
    browser.quit()

Chrome now has a headless mode:

op = webdriver.ChromeOptions()
op.add_argument('headless')
driver = webdriver.Chrome(options=op)

Try this code:

op = webdriver.ChromeOptions()
op.add_argument('headless')
driver = webdriver.Chrome(options=op)

Since PhantomJS has been deprecated, using headless versions of Firefox would be a viable option.

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get('https://www.google.com/')

You can import Options if you don't want to open a web browser.

from selenium import webdriver   # for webdriver
from selenium.webdriver.support.ui import WebDriverWait  # for implicit and explict waits
from selenium.webdriver.chrome.options import Options  # for suppressing the browser

Then in the code:

option = webdriver.ChromeOptions()
option.add_argument('headless')
driver = webdriver.Chrome(options=option)

And continue with the rest of the program.

It is possible, but not with the standard firefox driver / chrome / etc.

You would need to install PhantomJS. Just assign your WebDriver to an instance of phantomJS driver:

driver = webdriver.PhantomJS()

If you run your code now, no browser window will be opened.

Always follow the Documentation. Here is what selenium doc says. It provide a standalone jar.

  • Download the standalone jar. And run it with command 

    java -jar selenium-server-standalone.jar

  • Now you will see a stanalone server started.

  • Now set up your webdriver like below and rest part will be as it is.

    driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities={'browserName': 'htmlunit', 'version': '2', 'javascriptEnabled': True})

  • Summary code will be like.

    from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common.keys import Keys
driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', 
desired_capabilities={'browserName': 'htmlunit', 'version': '2', 
'javascriptEnabled': True})
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()

You can run Selenium headless, take a look at this question/answer: Is it possible to hide the browser in Selenium RC?

Especially for performance load tests, you should have a look at Apache JMeter.
