  • Innovative way to make MongoDB relational
  • Blends in with Apollo GraphQL making it highly performant
  • Reactive data graphs for high availability
  • Incredible performance

You can create test directory and configure dependencies (working directory is the root of this repo):

# create meteor app for testing
# you can add a specific release with --release flag, this will just create the app with the latest release
meteor create --bare test 
cd test
# install npm dependencies used for testing
meteor npm i --save selenium-webdriver@3.6.0 chromedriver@2.36.0 simpl-schema@1.13.1 chai

# Running tests (always from ./test directory)
METEOR_PACKAGE_DIRS="../" TEST_BROWSER_DRIVER=chrome meteor test-packages --once --driver-package meteortesting:mocha ../

If you use TEST_BROWSER_DRIVER=chrome you have to have chrome installed in the test environment. Otherwise, you can just run tests in your browser.

Another option is to use puppeteer as a driver. You'll have to install it with meteor npm i puppeteer@10. Note that the latest versions don't work with Node 14.

With --port=X you can run tests on port X.

Omit --once and mocha will run in watch mode.
