There is a testbox run command available that will run your unit or integration tests from the command line. All you need is to have your server running (it doesn't have to be a CommandBox server).
Run your test suite like so (modify the runner URL to match your site).
This will hit your runner URL and output a CLI-formatted report of your test results. If your test suite failed, the command will also return a failing status code when being run from your native shell. This makes integrations with CI tools like Jenkins or Travis-CI very easy since a failing test will fail your build automatically.
You can also set up the default runner URL in your box.json and it will be used for you. Setting the URL is a one-time operation.
You can also use a relative path and CommandBox will look up the host and port from your server settings.
The default runner URL of the testbox run command is /tests/runner.cfm so there's actually no need to even configure it if you're using the default convention location for your runner.
There are a number of settings you can provide to the testbox run command to control exactly what tests run and how much output is included. Each of these can also be set in your box.json. Run this for more information.
Here is an example of the non-verbose output.
If you run tests on a server with FusionReactor installed and you are using TestBox 2.9 or greater, you will have code coverage reported in the CLI output as a percentage as well as the LOC (lines of code) that were tracked.
