 The new files will contain the necessary boilerplate, they will go in the right place, and the CLI will make sure that file naming conventions are followed. For example, components must always have a dash in their names. Creating files by hand is not recommended because mistakes can lead to confusing error messages.

 ### What it does

+<!--alex disable failed-->
 `ember test` runs all of the tests found in the `tests` folder of the app. By default, it runs all the tests once and displays the results. We'll see things like syntax errors, linting problems, deprecations, and failed assertions in the command line output. By default, these tests are run in Headless Chrome. What headless means is, we won't see the visual output of the browser, but it's running them in a Chrome environment. This makes the test suite faster. To watch tests in the browser as they run, visit `http://localhost:4200/tests` while the local server is running.

 There were always two major issues with running Node.js on Windows: first and
 foremost, the operating system maintains a maximum length for path names, which
 clashes with Node's traditional way of nesting modules in `node_modules`. The
