BigBlueButton Puppeteer Tests

Tests for BigBlueButton using Puppeteer, Chromium and Jest.

Get BBB URL and Secret and configure .env file

To run these tests with an existing BigBlueButton server, make sure you have a server set up, and that you have the server's URL and secret. These will be the same URL and secret you would use to make API calls to the server. If you do not have these, you can find them by running bbb-conf --secret from the terminal in the server.

Copy the .env-template file to a new file, and name it .env. In the .env file, add your BigBlueButton server URL and secret, so the tests will know which server to connect to.

Setup

To run these tests, you will need the following:

• Ubuntu 16.04 or later
• Node.js 8.11.4 or later
• Docker

These instructions assume you have the BigBlueButton repository cloned into a directory named bigbluebutton.

First, you need to have the dependencies installed with meteor npm install, from the bigbluebutton-html5 directory. When Puppeteer installs, it will automatically install the Chromium browser in which the tests will run.

To run individual tests, you can also optionally install Jest globally with sudo npm install jest -g.

$ cd ../bigbluebutton-tests/puppeteer
$ npm install

Running the tests with an existing BigBlueButton server (All in one)

To run all the tests at once, run npm test.

Running a single test with an existing BigBlueButton server (Specific test)

To run a specific test from bash:

$ bash ../bigbluebutton-tests/puppeteer/run.sh -t testcase

Test cases list: webcamlayout/whiteboard/webcam/virtualizedlist/user/sharednotes/screenshare/presentation/notifications/customparameters/chat/breakout/audio.

If you have Jest installed globally, you can run individual tests with jest TEST [TEST...]. The tests are found in the .test.js files, but you may choose to omit file extensions when running the tests.

Debugging, Recording, Metrics and Evidences

Debugging

To debug the tests, you will need to set DEBUG=true; if DEBUG receives true, the logs will show in the console from which we start the tests.

Debugging output will look like below:

  console.log

Recording

To record the tests, you will need to set WITH_RECORD=true; if WITH_RECORD receives true, all tests will be recorded to .mp4 files, to keep track on what's going on and to have a good approach to catch problems or to have a proof that there are no problems.

Recording output will be saved under data/test-date-testName/recording; for example: data/test-19-01-2021-pollResultsChatMessage/recording.

PS: Recordings are just for manual testing.

Getting Metrics

To run the tests and get their metrics, you will need to set BBB_COLLECT_METRICS=true; if BBB_COLLECT_METRICS receives true, the metrics will be generated at the end of the test inside /data/test-date-testName/metrics folder; for example: data/test-19-01-2021-pollResultsChatMessage/metrics.

Getting Evidences

Generating evidences is about to take screenshots of the client during testing. And to realize this, assigning GENERATE_EVIDENCES in .env to true. This will take screenshots and save them in data/test-date-testName/screenshots; for example: data/test-19-01-2021-pollResultsChatMessage/screenshots.

Visual Regression

Our test suite includes visual regression specs that can be execute separately with npm run test-visual-regression (desktop only). It will take screenshots of various views and components of the client, save them inside the tests/puppeteer/__image_snapshots__ folder and put the failed cases into tests/puppeteer/__image_snapshots__/__diff_output__.
