PyUnit Automated Testing

Let's start with making sure Python is available on your system

For Windows


For Linux/Mac:
  • Run python --version to see which python version is currently installed, make sure it is 2.5.X or above.
  • OS X, Ubuntu and most other Linux distro's come with Python pre-installed.

Set up your first Python test with PyUnit

First, make sure you have installed the correct Python Packages: 

sudo easy_install pip
sudo pip install selenium
sudo pip install testingbotclient


You are now ready to start testing with our Selenium grid.
More information + source code is available in our GitHub repository.


Example Code

import unittest
import sys

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from testingbotclient import TestingBotClient

class Selenium2TestingBot(unittest.TestCase):

	def setUp(self):
		desired_capabilities = webdriver.DesiredCapabilities.FIREFOX
		desired_capabilities['version'] = 'latest'
		desired_capabilities['platform'] = 'WINDOWS'
		desired_capabilities['name'] = 'Testing Selenium with Python'

		self.driver = webdriver.Remote(
			desired_capabilities=desired_capabilities,
			command_executor="http://key:[email protected]/wd/hub"
		)
		self.driver.implicitly_wait(30)

	def test_google(self):
		self.driver.get('http://www.google.com')
		assert "Google" in self.driver.title

	def tearDown(self):
		self.driver.quit()
		status = sys.exc_info() == (None, None, None)
		tb_client = TestingBotClient('key', 'secret')
		tb_client.tests.update_test(self.driver.session_id, self._testMethodName, status)

if __name__ == '__main__':
	unittest.main()

Configuring capabilities

To let TestingBot know on which browser/platform you want to run your test on, you need to specify the browsername, version, OS and other optional options in the capabilities field.



Before 
driver = webdriver.Firefox()

After 
driver = webdriver.Remote(
  command_executor='http://key:[email protected]/wd/hub',
  desired_capabilities=desired_caps)

To see how to do this, please select a combination of browser, version and platform in the drop-down menus below:


1. Select a Platform
2. Select a Browser


Testing Internal/Staged Websites

We've built TestingBot Tunnel, to provide you with a secure way to run tests against your staged/internal webapps.
Please see our TestingBot Tunnel documentation for more information about this easy to use tunneling solution.


The example below shows how to easily run a PyUnit WebDriver test with our Tunnel:


1. Download our tunnel and start the tunnel:

java -jar testingbot-tunnel.jar key secret

2. Adjust your test: instead of pointing to 'hub.testingbot.com/wd/hub' like the example above - change it to point to your tunnel's IP address.
Assuming you run the tunnel on the same machine you run your tests, change to 'localhost:4445/wd/hub'. localhost is the machine running the tunnel, 4445 is the default port of the tunnel.


This way your test will go securely through the tunnel to TestingBot and back:


import unittest
import sys

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from testingbotclient import TestingBotClient

class Selenium2TestingBot(unittest.TestCase):

	def setUp(self):
		desired_capabilities = webdriver.DesiredCapabilities.FIREFOX
		desired_capabilities['version'] = 'latest'
		desired_capabilities['platform'] = 'WINDOWS'
		desired_capabilities['name'] = 'Testing Selenium with Python'

		self.driver = webdriver.Remote(
			desired_capabilities=desired_capabilities,
			command_executor="http://key:[email protected]:4445/wd/hub"
		)
		self.driver.implicitly_wait(30)

	def test_google(self):
		self.driver.get('http://www.google.com')
		assert "Google" in self.driver.title

	def tearDown(self):
		self.driver.quit()
		status = sys.exc_info() == (None, None, None)
		tb_client = TestingBotClient('key', 'secret')
		tb_client.tests.update_test(self.driver.session_id, self._testMethodName, status)

if __name__ == '__main__':
	unittest.main()

Other Options

We offer many other test options, for example: disable video recording, specifying a custom Firefox Profile, loading Chrome/Firefox/Safari extensions, running an executable before your test starts, uploading files, ...
See our list of test options for a full list of options to customize your tests.

Parallel Testing

Parallel Testing means running the same test, or multiple tests, simultaneously. This greatly reduces your total testing time.

You can run the same tests on all different browser configurations or run different tests all on the same browser configuration.
TestingBot has a large grid of machines and browsers, which means you can use our service to do efficient parallel testing. It is one of the key features we provide to greatly cut down on your total testing time.


Queueing

Every plan we provide comes with a limit of concurrent VMs (how many tests you can run in parallel).
For example: if you have a plan with 5 concurrent VMs, it is possible to start more tests. TestingBot will queue the additional tests and run the tests as soon as slots become available.


Example code (Selenium WebDriver Parallel testing)

from threading import Thread
from selenium import webdriver
import time

API_KEY = "KEY"
API_SECRET = "SECRET"

def get_browser(caps):
	return webdriver.Remote(
			desired_capabilities=caps,
			command_executor="http://%s:%[email protected]/wd/hub" % (API_KEY, API_SECRET)
		)

browsers = [
  { "platform":"WINDOWS", "browserName" : "firefox", "version" : "latest-2", "name" : "FF" },
  { "platform":"WINDOWS", "browserName" : "firefox", "version" : "latest", "name" : "FF" },
  { "platform":"LINUX", "browserName" : "chrome", "name" : "Chrome" },
  { "platform":"MAC", "browserName" : "safari", "version" : "latest", "name" : "Safari" }
]
browsers_waiting = []

def get_browser_and_wait(browser_data):
	print "starting %s" % browser_data["name"]
	browser = get_browser(browser_data)
	browser.get("https://testingbot.com")
	browsers_waiting.append({ "data" : browser_data, "driver" : browser })
	print "%s ready" % browser_data["name"]
	while len(browsers_waiting) < len(browsers):
		print "browser %s sending heartbeat while waiting" % browser_data["name"]
		browser.get("https://testingbot.com")
		time.sleep(3)

thread_list = []
for i, browser in enumerate(browsers):
	t = Thread(target=get_browser_and_wait, args=[browser])
	thread_list.append(t)
	t.start()

for t in thread_list:
	t.join()

print "all browsers ready"
for i, b in enumerate(browsers_waiting):
	print "browser %s's title: %s" % (b["data"]["name"], b["driver"].title)
	b["driver"].quit()
