Python-Selenium framework module

Project description

pscore provides a range of selenium webdrivers for local, grid and saucelabs execution, including test setup and teardown. It has been tested and used with the nose2 test runner which enables multi-threaded test execution. pscore offers up a WebDriverTestCase which can be sub-classed in your automation test cases and will provide access to a webdriver object via self.driver

An example test looks like this:

from pscore.core.wd_testcase import WebDriverTestCase
from pscore.nose2.tags import tagger
from the_internet_model.pages.home import Home

class TestTheInternet(WebDriverTestCase):

 def test_can_load_homepage(self):
     home = Home(self.driver).load()
     self.assertTrue(home.is_loaded(), "Error loading homepage")

And is run like this:

nose2 -c nose2.cfg -A tags=Home

Test configuration is managed by reading environment variables.

Required environment variables

  • PSCORE_ENVIRONMENT - Specifies the execution environment. Accepted values: grid, local, saucelabs, sauce, amazon
  • PSCORE_BROWSER - Specifies the browser. Accepted values: ie, chrome, firefox, iphone, ipad, android, safari (ie, chrome, firefox, android options can be used on local development)
  • PSCORE_HOMEPAGE - Specifies the homepage. e.g.


  • PSCORE_BROWSER_VERSION (e.g. if using saucelabs) - specify browser version
  • PSCORE_SCREENSHOT_DIR - Specifies the directory to write screenshots to
  • PSCORE_AGENT_ID- (optional) name to set the environment of your test run e.g. "MyTeamIntReview"
  • PSCORE_SELENIUM_HUB_URL - Specifies the URL of a standard selenium hub instance e.g. http://gridhub:4444/wd/hub
  • PSCORE_HTML_DUMP_ON_FAILURE - when True, a failing test will add page source to log files during teardown.


  • PSCORE_SAUCE_USERNAME - The username to use for Saucelabs authentication
  • PSCORE_SAUCE_KEY - The access key to use for Saucelabs authentication
  • PSCORE_SAUCE_TUNNEL_ID - in order to see internal test environments, we need to use a sauce connect tunnel - use the tunnel ID name
  • PSCORE_SAUCE_PARENT_ACCOUNT - if you are a sub-account of someone else, put that username here

Driver Extensions

pscore offers some extensions to the webdriver API


There are some wait helpers:

a_findable_element = By.XPATH, "//div[@id='start']/button"
some_spinner = By.ID, "alert_spinner"
how_long_to_wait = 10 #seconds
# We can wait until something appears
element_found = self.driver.wait.until_visible2(a_findable_element, how_long_to_wait)
# or wait until something has gone away
element_gone = self.driver.wait.until_not_visible2(some_spinner, how_long_to_wait)
# Exceptions are suppressed so these methods always return true or false

Using Custom Capabilities

Usually, we would suggest using the environment variables above for test configuration. There will be times when you may want to use custom capabilities. Here is an example of how you can do that. We still set the PSCORE_ENVIRONMENT to either sauce, local or grid.

caps = dict(
    platform='Windows 8',

class SimpleSauceCapsTest(WebDriverTestCase):
    def setUp(self):
        # You must assign custom_caps
        self.custom_caps = caps
        # Then call super
        super(SimpleSauceCapsTest, self).setUp()

    def test_customCaps(self):
