Acceptance Testing in HTML Client. Getting Started

    The test suite for HTML5 client is currently under active development. The following instructions will help you install all the necessary tools and libraries to run the exiting specs and start writing your own tests.

    Run Selenium Server

    Assuming that you installed HTML5 client already, you should have all npm packages including webdriver-manager installed at this stage. We use webdriver-manager tool to keep track of the latest Selenium Server and Chrome / Firefox WebDrivers.

    From the bigbluebutton/bigbluebutton-html5 run:

    ./node_modules/.bin/webdriver-manager update
    

    This command will download the latest versions of the WebDrivers and Selenium.

    Along with the Selenium and WebDrivers, you need to install the browsers itself.

    How to install Chrome:

    wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
    sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
    sudo apt-get update
    sudo apt-get install google-chrome-stable
    

    How to install Firefox:

    sudo apt-get install firefox
    

    There are 3 browsers currently used in the test specs (multiremote mode): Chrome Stable/Mobile, Firefox Stable.

    In order to run headless browser, we will use Xvfb display server:

    sudo apt-get install xvfb
    

    At this point, you can run the Selenium server (from under bigbluebutton/bigbluebutton-html5):

    xvfb-run ./node_modules/.bin/webdriver-manager start
    

    If you get an error Xvfb failed to start, run it with an -a option (Xvfb will use another display if the current one is already in use):

    xvfb-run -a ./node_modules/.bin/webdriver-manager start
    

    Congratulations! You have Selenium server up and running. It is ready to handle your test cases. Now, keep the xvfb-run process running and continue in a new terminal session.

    Run the test specs

    We use WebdriverIO interface to write the acceptance test cases. In order to execute the existing tests, you need to use wdio test runner. By default, it will look into any *.spec.js file inside the /home/firstuser/dev/bigbluebutton/bigbluebutton-html5/tests/webdriverio/specs directory. You can change the location of the test specs by modifying the wdio config file: wdio.conf.js (inside the webdriverio directory).

    Before proceeding any further, make sure HTML5 client is up and running. Node.js installation is also required:

    sudo apt-get install nodejs-legacy
    

    You can run all of the existing test specs with a single npm command:

    cd /home/firstuser/dev/bigbluebutton/bigbluebutton-html5
    npm test
    

    Test suites

    To make it easier to run a single specific set of tests, we group the specs into test suits. All the suits are defined in wdio.conf.js.

    To run a single test suite, you need to pass its name to the npm script:

    npm test -- --suite login
    

    If you want to run a single spec (test file), --spec option can be used:

    npm test -- --spec ./tests/webdriverio/specs/login.spec.js
