You can check that everything works by launching the test suite:

grunt

If you want to launch tests from a single test, you can specify the file as command line argument. For example, you can launch the backend tests on the test/unit-backend/webserver/index.js file like this:

grunt test-unit-backend --test=test/unit-backend/webserver/index.js

Note: This works for backend and midway tests.

Some specialized Grunt tasks are also available, check the Gruntfile.js file for more:

grunt linters # launch hinter and linter against the codebase
grunt test-frontend # only run the fontend unit tests
grunt test-unit-backend # only run the unit backend tests
grunt test-midway-backend # only run the midway backend tests
grunt test # launch all the testsuite
