I am trying to execute the built in until test provided in the metacoin example. I installed Mocha into my project.

I then execute this command: npm test from my console.

I am getting the following error:

C:\Dev\Blockchain\TruffleDemo\test\metacoin.js:1 (function (exports, require, module, __filename, __dirname) { var MetaCoin = artifacts.require("./MetaCoin.sol"); ^ ReferenceError: artifacts is not defined

Any ideas on what I might be missing? Thank you for the assistance!
