Travis CI

Applies to CrossBrowserTesting SaaS, last modified on January 19, 2022

For this document, we provide example tests located in our Travis CI GitHub Repository.

Travis CI is a continuous integration tool that lets you automate your development process quickly, safely, and at scale. Through Travis CI's integration with GitHub, every time you commit code, a build is created and automatically run, allowing you to test every commit.

In this guide we will use Travis CI with GitHub for testing using the Selenium WebDriver and Python programming language.

Set up Travis CI

  1. Navigate to your GitHub account and create a new repository.

    Create repository

  2. Add file tests/


    from import expected_conditions as EC
    from import WebDriverWait
    from import By
    from selenium import webdriver
    import unittest
    import requests
    import os

    class LoginForm(unittest.TestCase):
        def setUp(self):

            # Put your username and authkey below
            # You can find your authkey at
            self.username = os.environ.get('CBT_USERNAME')
            self.authkey = os.environ.get('CBT_AUTHKEY')

            self.api_session = requests.Session()
            self.api_session.auth = (self.username,self.authkey)

            self.test_result = None

            caps = {}

            caps['name'] = 'Travis CI Example'
            caps['browserName'] = 'Chrome'
            caps['version'] = '75'
            caps['platform'] = 'Windows 10'
            caps['screenResolution'] = '1366x768'
            caps['username'] = self.username
            caps['password'] = self.authkey

            self.driver = webdriver.Remote(


        def test_CBT(self):

                self.driver.find_element_by_css_selector('body > div > div > div > div > form > div.form-actions > button').click()

                elem = WebDriverWait(self.driver, 10).until(
                    EC.presence_of_element_located((By.XPATH, '//*[@id=\"logged-in-message\"]/h2'))

                welcomeText = elem.text
                self.assertEqual("Welcome", welcomeText)

                print("Taking snapshot")
                snapshot_hash ='' + self.driver.session_id + '/snapshots').json()['hash']

                self.test_result = 'pass'

            except AssertionError as e:
                # log the error message, and set the score to "during tearDown()".
                self.api_session.put('' + self.driver.session_id + '/snapshots/' + snapshot_hash,
                    data={'description':"AssertionError: " + str(e)})
                self.test_result = 'fail'

        def tearDown(self):
            print("Done with session %s" % self.driver.session_id)
            # Here we make the api call to set the test's score.
            # Pass it it passes, fail if an assertion fails, unset if the test didn't finish
            if self.test_result is not None:
                self.api_session.put('' + self.driver.session_id,
                    data={'action':'set_score', 'score':self.test_result})

    if __name__ == '__main__':

  3. Add file .travis.yml to the new repository.


    sudo: false
    language: python
    # command to run tests
    script: pytest
          - pip install selenium
          - pip install requests
