OP asked about running from node not from mocha  This is a very common use case  see Using Mocha Programatically  This is what injected describe and it into my tests   mocha ui  bdd   run function  failures        process on  exit   function            process exit failures                   I tried tdd like in the docs  but that didn t work  bdd worked though

To run tests with node npm without installing Mocha globally  you can do this       Install Mocha locally to your project  npm install mocha --save-dev       Optionally install an assertion library  npm install chai --save-dev       In your package json  add a section for scripts and target the mocha binary   scripts        test    node   node modules mocha bin mocha          Put your spec files in a directory named  test in your root directory      In your spec files  import the assertion library  var expect   require  chai   expect        You don t need to import mocha  run mocha setup  or call mocha run        Then run the script from your project root   npm test

if you are using vscode  want to debug your files  I used tdd before  it throw ReferenceError  describe is not defined  But  when I use bdd  it works   waste half day to solve it                   type    node          request    launch          name    Mocha Tests          program      workspaceFolder  node modules mocha bin  mocha          args              -u            bdd     set to bdd  not tdd          --timeout            999999            --colors              workspaceFolder  test      js                  internalConsoleOptions    openOnSessionStart

Assuming you are testing via mocha  you have to run your tests using the mocha command instead of the node executable   So if you haven t already  make sure you do npm install mocha -g  Then just run mocha in your project s root directory
