Python-Selenium framework module
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): @tagger('Home') 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:
- PSCORE_BROWSER - Specifies the browser. Accepted values:
androidoptions can be used on local development)
- PSCORE_HOMEPAGE - Specifies the homepage. e.g. http://www.google.com
- 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
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
caps = dict( browserName='chrome', platform='Windows 8', version='47.0', screenResolution='1280x1024' ) class SimpleSauceCapsTest(WebDriverTestCase): def setUp(self): # You must assign custom_caps self.custom_caps = caps # Then call super super(SimpleSauceCapsTest, self).setUp() @tagger('dbg') def test_customCaps(self): self.driver.get("http://www.google.com") self.assertTrue(False)
- Fixed a bug where pscore was not passing testname while creating driver.
- Changed logger method to exclude the params name when creating log files.
- Fixed a bug in pscore which was failing to upload logs to reporting service when using params
- Added Applitools support for use with Saucelabs
- Selenium 2.52.0 bindings
- Make test fail and teardown gracefully if an uncaught exception is thrown from an overridden tearDown implementation
- Prevent setup logic from attempting to maximise window when using custom mobile capabilities
- Support for Custom Desired Capabilities (see examples above)
- New flag PSCORE_HTML_DUMP_ON_FAILURE will place driver.page_source into log file if a test fails.
- Sanitize log file names when running parameterized tests.
- Selenium 2.50.0 bindings
- Sauce Android caps updated to support 5.1
- Compatible with Python 3.5.*
- Update Selenium version to 2.49.2
- Fixed an issue where a logger instantiation error caused tests not to execute
- Teardown URL logged for all PSCORE_ENVIRONMENT s
- Update Selenium version to 2.48.0
- Added driver.wait.until_visible2 and driver.wait.until_not_visible2. Example usage above
Fix for displaying sauce reports when there is a timeout on sauce side
Updated Sauce caps to use the latest keys and added support for safari 9
Minor fix for handling exceptions when artefact service was down
Bumped the selenium version to use 2.47.3
Added the capability to log the grid node ip
Fixed the bug which was not downloading the chromedriver and iedriver when trying to run the tests locally
Missing changelog file was causing setup.py to crash
Minor fixes in the way error messages are captured
