The best way to run the Code tests is from within VS Code. Simply press CMD+Shift+T (Ctrl+Shift+T on Windows) to launch the tests.

If you wish to run the tests from a terminal, from the vscode folder run:

cd vscode
mocha

Alternatively, you can run them from any browser. Simply open the URL provided by the following command:

cd vscode
mocha --browser

You can use VS Code to debug your tests. Switch to the Debug viewlet, pick the Unit Tests debug target and press Play.

The following command will create a coverage folder at the root of the workspace:

mocha --coverage
