  # ng test
  
  ## Overview
  `ng test` compiles the application into an output directory
  
  ### Running unit tests
  
  ```bash
  ng test
  ```
  
  Tests will execute after a build is executed via [Karma](http://karma-runner.github.io/0.13/index.html), and it will automatically watch your files for changes. You can run tests a single time via `--watch=false` or `--single-run`.
  
  You can run tests with coverage via `--code-coverage`. The coverage report will be in the `coverage/` directory.
