How to write integration tests
Integration tests are initiated from the client side, and test to ensure that client-server interactions work as intended. Currently, integration tests only check that Meteor method implementations function correctly.
Each collection class contains its tests in a "sibling" file. Integration tests for the CourseCollection class are located in CourseCollection.app-test.js.
The test file names are important: Meteor wants integration tests to be in files with the suffix app-test.js.
Many tests require the database to be initialized with test values. RadGrad provides "database fixture" files for this purpose. See the DB fixture chapter for more details.
Running all integration tests
To run all the integration tests, run this command:
$ meteor npm run test-integration
This will run the integration tests (i.e. those files with a test-app.js suffix). Here's a sample invocation, again with some lines elided:
$ meteor npm run test-integration
> radgrad@ test-integration /Users/philipjohnson/github/radgrad/radgrad/app
> METEOR_NO_RELEASE_CHECK=1 TEST_BROWSER_DRIVER=nightmare meteor test --full-app --once --driver-package dispatch:mocha --port 3100

As you can see, in contrast to unit tests, no server-only tests were invoked.
Run a subset of integration tests
To run a subset of the tests you can set the environment variable MOCHA_GREP. If MOCHA_GREP matches the name of the test as defined in the describe statement those tests will run.
MacOS and Linux
For example:
$ export MOCHA_GREP="CourseCollection"
$ meteor npm run test-integration
> radgrad2@ test-integration /Users/philipjohnson/github/radgrad/radgrad2/app
> cross-env TEST_BROWSER_DRIVER=puppeteer meteor test --no-release-check --exclude-archs web.browser.legacy,web.cordova --full-app --once --driver-package meteortesting:mocha --port 3300
